Cake overlap on wooden beams Cold attic. Warming of the attic overlap on wooden beams and the reinforced concrete plate

If you are detaining the house, almost the finish work has already been done and you do not know whether it will be waiting for the attic or this case will wait, and in general it is necessary at this stage - this article will help you. Here we will look at the insulation of the attic overlap with materials of different types, with step-by-step illustrations, advice of experts and useful videos.

And also reveal many important moments why insulation is so necessary and how in fact there should be a cake of the attic overlap on wooden beams and on a reinforced concrete plate - step by step.

What insulation are suitable for the attic?

It is necessary to warm the attic overlap when the attic space does not plan to use for housing. Those. We are talking about a cold attic, whose roof rods are not warmed at all. And for the overlap, not all the same materials are already suitable, then they are selected for the skates.

Mineral wool: without harmful dust

So, when insulation of the attic overlap of mineral wool, the so-called tension method is correctly applied. Its essence is that the insulation material first is stacked - and so that it is prescribed between the beams.

After that, it is littered into three layers of a slab or rolled insulation from mineral wool, a total thickness of about 150 millimeters, and it is covered with a vapor insulating film from above. After that, already plywood, which should not be thinner than 18 millimeters.

Polystyrene foam and foam: simplicity of laying

The insulation of the attic overlap with the help of polystyrene foam, the main advantage of which is that there is no need for vapor barrier, and all the gaps are easily compacted by the mounting foam.

Injustful insulation: Fashion and rationality

Recently, the insulation of the attic overlap by the method of strangling has become particularly popular.

The main advantage of the intelligent insulation is that it fills all the emptiness by itself, which is, and create a smooth continuous layer. In which there are no joints, there are no seams and there is no adjustment, and for which there is no need to cut the individual small pieces of barbed insulation to shut something.

Today, two types of insulation of the insulation are predominantly used for the insulation of cold attics in Russia: Eco-eyewit and stiff wool.

Equata up to 80% consists of cellulose fibers, which are produced from ordinary waste paper, and by 20% of such additives, like a buran as an antipyrene and boric acid as an antiseptic. This insulation is high thermal conductivity.

But the stuffing cotton wool is obtained when grinding ordinary mineral materials for thermal insulation, which for some reason did not pass the acceptance of products.

For example, there were no sufficient density or proper structure of the fibers. And such a material is crushed and pack under heavy pressure, and therefore it is easy to transport it to the place of the object, where on arrival everything is breaking again.

But still most often used as an eco-engine material. The insulation itself in the process looks like this: one person must stay next to the installation and monitor its normal operation, at the same time loading the material. And the second person climbs into the attic along with the hose, makes a cross-shaped incision (just between beams) in charge of the hose in this incision, and fills the cavity with the material.

Plus, for insulation of a cold attic applied relatively inexpensive bulk materials:

What parameters of the insulation should pay attention to?

In no case we urge you to acquire the most expensive heat-insulating materials for the insulation of your attic overlap. But note that the larger the longer any known company produces materials for this purpose, the more it pays attention to the quality, changing their volumetric weight, improving its products and increasing thermal insulation coefficients. And this is already talking about something.

Otherwise, always pay attention to such parameters of insulation, which are important for wooden overlap, and have no for concrete - and vice versa.

Parameter number 1. Biostost

It is about such a insulation that often remains open, bugs did not start or what other animals. This is especially true of mice, which like to live on warm and dry (and, most importantly, deserted) attic.

Another important requirement for an attic insulation is a water resistance. The rainy drops or simply moisture in it do not have to lead to the process of rotting.

One of the most persistent insulation is recognized glass gamble:

Parameter number 2. Thermal conductivity

The main requirements for insulation for the attic ceiling is the ability to maintain thermal insulation properties for a long time.

When buying a insulation, pay attention also to such an interesting point: Modern manufacturers of thermal insulation materials always indicate in the technical characteristics of the three thermal conductivity coefficient of the material: in a dry state, at a temperature of 10 ° and 25 °, and the humidity of the category A and B.

You need to look at the thermal conductivity coefficient in a dry state, or at a temperature of 10 degrees, because it is the normal climate situation in the attic. For more accurate and detailed thermal calculations you will need a SNiP table.

And now we note that moment. You will certainly be selected when buying a heater advise to take a heater with as much as possible in thermal conductivity. But in fact, it makes sense only for residential attics, because when you have to warm the roofs, then too thick materials between the rafters do not pave. Therefore, we need materials that will be warm as worse as worse, but at the same time have a small thickness.

But for the attic overlap just the thickness of the insulation is not a critical factor, and you can save on it. Just take the insulation of the cheaper, but thoroughly, even with high thermal conductivity. You are all compensated by the height of the warming itself.

Parameter number 3. Weight

Depending on the chemical composition, each insulation has its own bulk mass. Thus, such materials such as basalt, glass and any other inorganic and organic compounds are most often used as a basis for fibers. From their type, the heat insulating material itself becomes either light or heavy. And the form of all these materials is ensured by the elasticity of the fibers: how much they are straightened between the beams of the overlap.

Note that heavy insulation form holds better due to the rigidity of its fibers. And the best stability for insulation of the attic overlap has foam insulation, which in this parameter are equated with rigid stone watts. But there is a point: the same mineral wool insulation, which inserted between the beams of overlapping, is easy to deal with and tightly cut to the wood, and the foam will not do it, and emptiness is formed - the bridges are cold. Therefore, you will have to additionally use a foam can close all the gaps.

But if you make the insulation of the attic overlap over the reinforced concrete plate materials based on foam, then there will be only advantages. Not to mention that the concrete overlap itself is already a considerable weight and creates a serious burden on the walls and the foundation of the house, and the use of light insulation for him is only a big bonus.

And unlike concrete overlap, the attic can withstand sufficiently limited load. Therefore, the weight of the insulation in this regard is also not the last moment. After all, there are already many variations: the same cubic meter of thermal insulation can weigh both 11 kilograms, and all 350 is the norm.

One of the most severe insulation - basalt wool:

Parameter No. 4. Resistance to moisture

Rainly falling raindling moisture in the insulation or roofing leaks should not run the process of rotting. Bad, if after six months - a year a new insulation begins to decompose from the inside, making an unpleasant smell of dampness.

Therefore, the insulation of the attic overlap on wooden beams and in concrete is quite common with the help of foam or polystyrene foam, which are known for their almost zero hydrophobicity.

Parameter No. 5. Ecology

Another point: the attic insulation should not allocate any toxic and sharp smell in terms of substances, despite the fact that, perhaps, no one will walk in such an attic.

It's all about ventilation: Sooner or later, the insulation molecules are picked up by air and entered into residential premises, which is unsafe for tenants at home. Therefore, choose such a heater that corresponds to sanitary standards.

Parameter No. 6. Saving form

Another important point is the form stability of the selected insulation. Thus, special laboratory tests showed that with the time of heat loss through the slots between the plates or the matte heat insulator can reach 40%. And this is despite the fact that the material itself during the same time may not change its coefficient of thermal conductivity at all, if it remained dry.

And therefore, the stability of the shape and size of the material with time is very important. For concrete overlap, the attic such gaps will not be critical, because here the overlap itself is quite thermally insulating, which cannot be said about the attic overlap.

But the problem is that in technical information on modern thermal insulators such a parameter as a form or stability, not found.

Parameter number 7. Fire safety

And the last moment: the attic insulation must comply with all the requirements of fire safety. Take the same popular EcoWhat, which is not just made of ordinary waste paper and pieces of newspapers. It would seem that everything is simple and ingenious, why don't you chop papers either, and just not fall asleep by the attic? Will it be worse? After all, it also involves the principle of loosenness, like animal wool, when the air molecules are stuck between small elements.

Let's just say: yes, the insulation of this method will not be worse, but it is the old dry paper and wood most often leads to an unexpected fire. That is why modern cellulosic insulation is necessarily processed by special chemicals against fire.

If we are talking about the flammability of materials, it is important that the insulation does not only burn, but also attenu. Just remember that everything is burning in the epicenter of fire, and iron and concrete, but if a spark falls on the attic overlap, then the insulation should not light up. That's what we are talking about.

This is how the insulation cake should look like the attic:

Various issues: how, on which side and is it necessary?

For insulation of roofing overlap made of wood and concrete, the vapor permeability of the insulation is of great importance. So, all insulation that are manufactured today in the form of plates and rolls can be divided into "cotton" and "foam", as construction contractors like it.

We will draw the heat-insulating materials from organic and mineral fibers - this is mineral wool, stone wool and glass wool insulation. All these materials are formed by solidifying the plastic mass of various chemical origin. And all these materials are about the same thermal conductivity coefficient: in the range of 0.04.

All these materials consist of fibers that are intertwined with each other. They do not form any closed pores, and the water vapor easily penetrates and removes through them. Therefore, all cotton heaters are vapor-permeable materials. For which their fibers in production conditions are additionally covered with a special water repellent substance, and insulation are also hydrophobic: water molecule from water vapor is not allowed to penetrate inside and soak the insulation. It can only be attached to its surface, and when the critical mass accumulates, it is transformed into a drop and roll down. It turns out that hydrophobized cotton insulation is not a wetral vapor-permeable material.

Therefore, so far, scientists from all over the world can not come to an unequivocal conclusion: the vapor permeability of building insulation is good or bad. Let's just say that if you equip the attic overlap on wooden beams, you'd better put vapor-permeable materials on it so that wooden rafters that took moisture from the lower residential premises (and the water vapors are always up), they could pass it easily into the insulation . And from the insulation, they will easily come out outside - enough through end-to-end ventilation. But in terms of insulation overlap over concrete, there is no special difference. But there is such a point: when using vapor-permeable insulation, it is important that the insight into such a attic is organized by all the rules, and it does not prevent a separate ventilation system.

Note that there are no fibers in foam insulation, since such material is literally from the air. All foam insulation consist of a cellular structure, with closed bubbles and not closed, like a kitchen sponge. Therefore, such thermal insulators can be both vapor-permeable and non-param. For example, extrusion polystyrene foam, which is more known as a foam, passes water pairs between the balls, but the extrusion polystyrene foam is no longer.

What is interesting, you can use not only one type of insulation, and at once two to compensate for the shortcomings of each other. But at the same time, thermal insulation material with less vapor permeability must necessarily lie in front of the insulation with high vapor permeability. That is, first polystyrene foam, then wool. Otherwise, in the opposite case, the material with less vapor permeability will be a specific parobarrier for another material, he will simply start rotting and moisture will now go out.

How to insulate concrete overlap attic

If we are talking about the insulation of the attic overlap of concrete, then thermal insulation must be necessarily in the form of two or three layers with overlapping of the joints of each bottom layer. Moreover, it is very important that the entire surface is aligned so that anywhere there is no irregularities more than 5 millimeters - this is not difficult to achieve with modern leveling mixtures.

For concrete attic floors, the plates of extruded polystyrene is ideally suited as thermal insulation. They do not need vapor barrier, but if you put a foam - this is not extruded polystyrene foam, and then, of course, needed.

Additionally, if you need to walk later by this overlap, you can make a cement-sand tie up to 4 centimeters and put two layers of plasterboard sheets. Just be sure to do for such a screed path from the masonry grid, for which you will walk. Be sure to cross the joints between the plates of polystyrene foam scotch, so that cement milk proceeds between the plates.

The attic overlap itself is permissible to insulate both at the stage of manufacture and in almost any time of operation of the house itself. Of course, for the attic much more correctly insulate the overlap before you come to your new home.

In more detail about the process itself:

How to insulate wooden overlap attic

So, there are two main ways of insulation of the attic overlap: laying the thermal insulating layer inside the design of the attic overlap, and laying the insulation on top of it. For a cold and non-residential attic to cover something over the insulation and build a full-fledged floor is not necessary. But then, be sure to leave the running gearboxes - separate paths from the rarefied flooring throughout the attic area, it is necessary to maintain the roof.

Under the insulation you need to put vapor barrier, and in the form of a trough, so that it can protect the insulation from water vapor, which comes from the lower residential premises. But from this rule there is an exception: if the insulation was laid with good resistance, for example, this is a foam or extruded polystyrene foam, then vaporizolation is not needed here. But if we are talking about the attic with a particularly wet regime, for example, above the kitchen or sauna, the vaporizolation layer here needs to be installed serious.

Another method is tensioned when vaporizolation is just running between the beams. The disadvantage of this method is that the insulation between the beams turns out to be inserted insufficiently tightly.

And if the overlap is also made of ready-made firms, then this option is not suitable at all, because such emptiness quickly become so-called cold bridges. Therefore, a method in Russia is more popular in which the insulation is first stacked, then it is covered with vaporizolation, and only then - the finish line.

So, here's what the whole process of insulation looks like:

• Step 1. A vaporizolation is fixed between beams with a construction stapler.
• Step 2. Next cutting plates of mineral wool so that their width respectively the beam steps.
• Step 3. These plates are neatly inserted into the gap between the beams.
• Step 4. For a while, while the ceiling is not yet ready, so that the insulation does not fall out between the beams, it is supported by draft bars or stretched specifically for this durable thread.
• Step 5. Next, the diffuse membrane on top of the insulation is quickly mounted - so that the steam through it easily went out, and the droplets from the tube did not penetrate inside.

But we note about the last step also such a moment. Many experts believe that for the insulation, no diffuse membranes or windproof films are not needed, because in a cold attic heat insulation will be dried due to the natural ventilation of convection air flows, which easily penetrate through the holes and auditory windows.

How to leave running ladders in insulation

If you use soft thermal insulation materials for insulation of the attic overlap, you need to make running ladders over them - but only so that the cold bridges do not get. Therefore, it is better to take either tough materials, or insert the legs of the lads directly into the insulation.

That's all the tricks of insulation of the attic overlap of different types!

There are two types of attic space - a cold attic and a combined attic or attic. In a cold attic, the insulation is laid horizontally on the semi attack, and the temperature inside the cold attic is about the same as on the street.

The temperature inside the cold attic should not exceed 4 ° from the outdoor air temperature (the rules and norms of the technical operation of the residential foundation, the decision of September 27, 2003 No. 170, paragraph 3.3.2), i.e. If the temperature is on -15 ° C, then in the attic it should be no more than -11 ° C. If this difference is greater, then, for example, at an outdoor air temperature -5 ° C, the slope will be heated, the snow on the roof will be lifted and flushing on the cornice. There will be no cornice, because There is no warm premises under it, and water on it will turn into a lot, forming icicles. The more ice to form on the cornice, the greater the chance of leakage, above the load on the roof and above the danger of ice breakdown, which can lead to tragic consequences. All this reduces the service life, both roofing and roofs in general.

Fig. 1 Ventilation of a cold attic.

To ensure a normal temperature regime on a cold attic, first of all, it is necessary to warm the overlap between the attic and the residential room. The thickness of the insulation is calculated, based on several parameters, the main of which is the location of the house. The second most important criterion for compliance with the temperature mode of the attic space is the undercase ventilation.

In addition to insulation and ventilation on the temperature of the attic space, influence: the laughing covers of the exit to the attic, the output into the attic space of the ventilation pipes of the premises (kitchen, bathroom), an uninsulated hot water supply located in the attic and so on.

Roofing cake for a cold attic can be divided into two parts. The first part is to overlap between the attic and residential premises. The second part is on Skate.

The first part of the roofing cake depending on the type of overlap looks like this:

Fig. 2 Pie on concrete overlap.

Fig. 3 Pie on wooden overlap.

Parosolation serves to prevent wet air from entering the insulation. On a concrete basis, a bituminous rolled material is best used, with flustering. The lags use film vapor barrier with the obligatory scholars with sealing ribbons. As a vaporizolation, you need to use vaporizolation films D-FOLIE B, D-FOLIE B 90 or D-FOLIE BR.

The insulation is placed in a few layers with the dispersion of the joints to eliminate the cold bridges.

The hydraulic recreation membrane protects against weathering and moisture. The moisture can be formed due to condensate, due to the snow being thought out into the attic space, as well as due to possible leaks. The superdiffusion membranes D-FOLIE A 150 or D-FOLIE A 100 should be used as hydraulic protection.

In any case, regardless of the type of overlap, the insulation is not recommended to be covered on top completely plywood or boards. If it is necessary to occasionally walk through the attic space, it is better to provide tracks from the boards without closing the entire insulation.

The second part of the roofing cake using flexible tile on the cold attic looks like this:

During the construction of a private house to the arrangement of the attic, the case renders last. Since there is always enough free space, this room is usually used to organize seasonal storage, living attic arrangement or installation of the necessary equipment.

Depending on the nature of the use of space and the device of the attic overlap is selected, the material from which it is assembled, also carrying the ability. In this article we will tell how the attic of a private house is equipped correctly.

Device attic

The attic is a room, limited to the roofs and ceiling of the residential floor. This room can be used as a place of seasonal storage or in order to organize additional residential space. Depending on the nature of the use of the attic of residential buildings, divided into the following types:

• Residential. The residential attic of the house is called an attic, it can serve as an extra bedroom, living room, a bedroom or a cabinet. To use the attic as a residential premises, it should have a ceiling height of at least 2.2 meters, natural lighting, ventilation, heat insulation of the skates.
• Non-residential. Non-residential attic can be used to install any technical equipment, organization storage. In this case, the height of the attic room can be less than 2 meters, natural lighting may be absent, and the thermal insulation of the skate is replaced with an insulation of an attic floor.

Important! Performing repair or renovation of the house, it is important to immediately decide how the attic will be used to correctly calculate and design attic floors. This will depend on the form, material, the distance between the beams, which will ensure sufficient strength and the carrying ability of the structure.

Thermal insulation attic

Functions

The design of the attic overlap depends on the size of the house and the nature of the use of the undercase. The attic is a kind of aerial layer separating the heated space of the first floor and the roof and thermally insioning it. Its floor performs the following functions:

1. Carriage. The overlap between the upper floor and the attic is carried out by carrying function, so they must be quite strong, reliable, because people move on it, equipment, storage locations are installed.
2. Isolating. The premises of the unheated attic has a temperature not much higher than street. Therefore, overlaps perform a thermal insulating function, preventing the heating of heated residential floor. In order to maintain heat into their composition enters the layer of insulation.

Remember that the temperature regime, comfort, security of accommodation in the house depends on the correctness and quality of work on arrangement. Therefore, it is better to entrust the design, installation or repair of overlaps to professional craftsmen.

The diagram of the attic overlap

Overlapping device

Since the attic overlap combines an insulating and carrying function, it has a multilayer structure. Its components, complementing each other, are connected into a single system, ensuring the strength that carry the ability and durability. If you list all the layers of the attic ceiling, starting on the side of the attic, then it looks like this:

• Picture floor. Clean flooring is called a decorative floor covering, which is covered by the draft floor of the attic. If the underfloor room is dwelling, then laminate, treated wood, linoleum, parquet, are used to arrange the finishing floor. In the non-residential attic of the piston can not be at all.
• Rough floor. Cherno floor is called flooring from the board, which is attacked by lags. For its installation, use a cutting board with a thickness of 4-5 cm, in order to save it, it can be replaced with an unedged one.
• Lags. Lagas are called durable, smooth boards or bars, which are stacked perpendicular to the beams of flooring for floor mounting. Between the lags, the thermal insulation material is usually protected from below the layer of vapor barrier, and on top of the waterproofing layer.
• Beams. The framework of overlappings consists of durable, thick beams that are installed on the protrusions in the walls or fit into them. The beams carry all the cumulative weight of the structures, so they should have a greater carrying ability.
• Ceiling trim. Bottom overlap is trimmed with finishing material, for example, tree or drywall, to give an aesthetic appearance of the ceiling of the residential floor.

Note! Thermal insulation and vaporizolation are the same important components of the design as beams of overlaps or lags, as they protect wood and insulation from spraying, wetting and condensate. If you forget about insulating layers, the overlap will not last long and after 2-3 years it will need to repair.

Device of the attic overlap

Views

For the construction of attic floors, it is possible to use various weight, supporting ability, durability and, of course, the price of materials. The choice of the type of construction depends on the nature of the use of a subsecutive room, the total weight of overlapping and equipment, which will be installed in the attic. Distinguish the following types of attic floors:

Note that in most cases the attic overlap of wooden beams is the best option for a private house, cottage and a small cottage. It has the best value for money and quality, and with the right calculation and compliance with the installation technology, the repair does not need soon.

Construction requirements

Installation, repair and reconstruction of attic floors require a well-thought-out approach, because the safety of home use depends on them. To determine the maximum possible load, which the design may be subject to, the engineering calculation is performed, and then, based on the calculations, the project is drawn up. A number of requirements are presented to attractive overlaps:

• Load bearing capacity. This indicator depends on the material from which the beams are manufactured, as well as from the distance between them.
• Distance between beams. The maximum allowable distance between wooden beams allowed by the construction standards is 4 meters.
• Resistance to temperature drops. The beams should well withstand temperature fluctuations, since the difference between air temperature in the attic and residential premises exceeds 4 degrees.
• Madness. The overlap must protect against the penetration of cold air and moisture from the attic.

When designing it is important to take into account all requirements for the beams of the attic cessation so that the design is strong enough, reliable and durable. The distance between the carrier elements of overlapping should be calculated in accordance with the loads bold on it.

Montaja technology

In the presence of a certain construction experience, it is quite possible to install and repair the attic floors with your own hands. This operation is performed at the final stage of roofing work. Installation of attic overlaps is performed in the following sequence:

1. Installing beams. For a small private house, wooden floors are used, made from timber secting 150x150 mm or 200x200 mm. They are placed on the brick or concrete masonry of the walls.
2. Installation of lag. Perpendicular to the beams on the edge are set by lags from boards with a cross section of 150x50 mm in 60 cm increments.
3. Laying of thermal insulating material. Between the lags laid the insulation to prevent the penetration of cold air from the attic.
4. Laying draft and finishing gender.
5. Beam sheat from below for ceiling.

Consider to increase the service life of the attic floor, you can use the wood treated with an antiseptic. In addition, if you insulate the sex of the attic, then you need to provide waterproofing and vapor barrier.

cold attic cake on wooden beams, design, heat insulation, how to warm

The room in the attic of private home ownership is used for different purposes: storing temporarily unnecessary things, equipment installations or living room arrangements. Depending on what is the free space under the roof, choose the method of the attic ceiling.

What is a attic

The attic room limit the roofs and the ceiling of the residential floor. This place is often used to arrange an additional living area.

The attic of private households is two types:

1. Housing. It is called an attic. It can also equip the living room, office, bedroom, library, etc. The height of the room in this case should be at least 220 centimeters. In addition, it needs ventilation, natural lighting, carry out the insulation of the skates.
2. Non-residents. Such an attic space is usually used to accommodate technical equipment, storing old or unnecessary things. At the same time there will be enough 2-meter height, and natural lighting is not necessary. Instead of insulation, the skates make thermal insulation of the attic overlap.

When making a decision on repair or restructuring at home, you need to decide in advance, for what purposes the attic will be involved in making the calculation and the project of overlapping. The list of necessary materials and the gap between the beams depends on this. They must provide the required strength and carrying ability.

An attic overlap on wooden beams with their own hands: how to make yourself

When building the roof, there is always special attention to the design of the attic. After all, it is important that its overlap to be done technologically correctly, did not have excessive pressure on the walls and was able to carry out a load from the roof stored under the roof and sometimes a whole set of furniture.

Therefore, in this article we will deal with you in detail how the thoughtful overlap of wooden beams should be arranged: the features of its installation, the calculation of loads and fastening. And to help you will be our detailed illustration.

To begin with, we suggest you to watch a small video review of the device of the attic overlap on wooden beams, and then we will already disassemble the details:

The overlap is horizontal power structures that separate the residential floor from the attic room, and perceives the load on the weight of everything that is under the roof.

The overlap itself is the necessary element of rigidity, which also ensures the stability of the entire structure. Among all others, we will highlight the attic overlap, namely, its concrete appearance. Note that the general rules applies to all species, but some technical features in the arrangement of the attic overlap on the beams are still there.

The first one is rigidity and strength. Those. The overlap must be:

• Able to withstand the calculated loads and at the same time not to bend, it will not collapse. For example, the permissible magnitude of the deflection is only 1 to 250 from the length of the span.
• Secondly, the attic overlap should not be flip, and in no case should not hesitate when moving items on it or movement of people.
• And finally, noisely insulated to avoid unpleasant creaks when someone rises to the attic.

In private construction, two types of overlaps are predominantly used: wooden and reinforced concrete. The first are built on durable wooden beams, and the second - on beams, stoves and in the monolithic version. Also, the beams themselves can be steel, if you have to overlap quite large spans. But it is precisely in private house building to choose from the overlap material, it is most often affected by the economic factor.

The cost of the ceiling device is usually up to 20% of the estimates of the entire construction of the house, and labor costs are as much as 25%. Therefore, it is quite popular after all the construction of a wooden church of the attic - all due to its high operational characteristics and good noise insulation.

And one more important point: in the manufacture of wooden attic floors, you will not need a heavy lifting machinery, especially concrete pump.

The whole design consists of beams and boards, which are called black. The beams themselves may be carriers, they simply are located near or are fixed in a special way that much more reliable. Standard sizes of beams - 20-40 centimeters in height and 15 meters long, plus 8-20 centimeters width.

Unlike reinforced concrete blackscape, wooden mounted dry. By weight it is much easier, therefore, it is better to use exactly the overlap. On the other hand, the wooden floors are the most sound-proof, so you will have to spend on additional measures.

Beams are located at a distance of 60 centimeters to 1.5 meters. Of course, the more often you install them, the greater the load will be able to withstand in the future the attic, but also a greater load will have to endure the foundation at home.

On wooden attic ceiling, light partitions are usually mounted - most often framework, to which attic rafters are attached directly. It is necessary to install them perpendicular to beams or edges.

But if the inner walls of the attic for some reason have to be put in parallel to ribs or beams, which is not at all according to the rules, then the designs in these places need to be reinforced. Most often, fragments of boards are used as such elements, which are attached perpendicular to overlapping edges.

Many are wondering: And where to properly install wooden beams of overlapping? In the walls, on the walls or even to bring them out a little? It depends on what kind you will have a attic and whether you will use it in the future as a residential premises. Mansard today is very popular!

So, here is an economy version that allows in the future without any problems to redo the attic into the attic. True, very close:

And therefore, if you have such plans and you are not even sure now, whether there will be another place under the personal account or billiard room in the project, then make the walls higher to install the beams of overlapping down.

What will it give? In such an attic there will be much more useful space, fewer sharp corners and it will be much warmer:

But if at your project, the attic was originally planned as a separate and spacious room, as if sucking on the house, then the attic beams need to be installed as strong as in the inter-storey overlap, and they also attach them to anchors in Aropoyase:

Here is a great step-by-step example, as such attic and how strong such a flood should be:

There are several types of attic overlap on wooden beams. Each of them is their destination and its pros and cons.

Platform: for a cold attic

As for the frame houses, the overlap in them is recommended on the "platform" system. That is, after installing the walls, beams are stacked and a platform is created, and a workforce for the future floor of the attic at the same time. It is important here not to have excessive pressure on fragile walls, so the attic coating will not be calculated on the piano in the corner.

In this case, the beams are installed on the strapping bar, which is used as Maurolat:

Hard shield: for uniform shrinkage

But in the house with walls from a log or bar as an attic overlap according to the rules, a hard shield is equipped, which, when shrinking the walls, will smoothly descend along with them, and be surely evenly.

Economy Flooring: to save time

As a separate type of ingredial overlaps, prefabricated wooden floors should be allocated. The main chip is in the use of special fasteners that are made of galvanized steel. Their thickness and quality is calculated depending on the level of future loads on the overlap.

Standard attic floors on beams with a timber and wooden lags appeared at the end of the 20th century, and after them became more fashionable overlaps from a wide board.

Ready farms: for residential attic

Today, in fashion, special ready-made firms for the arrangement of the attic overlap. In fact, this is not a new building market, such firms appeared at the end of the XVI century and found their second birth at the end of the twentieth. Canadian companies that have been engaged in construction developed special programs for calculating such firms and their exact form with assembly lines.

Ribbed beam overlap: for private house-building

In our country, new types of wooden floors begin to appear, which until that time were popular only abroad. It is light wooden floors. They are relevant for private construction, when the system uses a fairly light wooden frame as a system.

The essence of the overlap is that "ribs" are installed every 30-60 centimeters, and they are covered with a trim. As the "ribs", wooden beams are taken by a height of about 20 and 28 centimeters, and 45 centimeters thick, and up to 5 meters thick. They are made of natural wood and are combined with special bundles from the boards, covering the skin with a chipboard or fiberboard.

Therefore, we highlight from the main advantages of the ribbed attic overlap of fast and easy installation. Of the minuses: the need to process with flame retardant, less strength and low sound insulation properties. And, of course, such boards are more sensitive to harsh fluctuations in humidity and temperature. And also, if the fungus or some insect decides to eat such overlapping over a few years, he will eat it much faster than thick beams.

Below this design is sewn with suspended ceiling of plasterboard plates. Mineral wool is stacked between the edges on top. It is she who will provide fireproofiness and sound insulation of the whole wooden overlap.

Ribbed shots of the attic cost much cheaper than beam - it is quite reasonable and rationally, if you are a non-residential room you will not warm and make a living attorney. Then you may not worry about the supportive ability of such a base. The only negative is that the beams are more familiar to Russian homes, and the ribbed overlap is almost no different in appearance from the monolithic. Therefore, ribor-beamy attic overlaps are more common in Russian homes.

The bar for the device of such a attic overlap you need to take a rectangular shape, and strictly, and not a rhombus. And must, when buying such a bar, take with you the most ordinary school line, because it often happens that many are going to build a 18x15 cm overlap, and as a result, they are built from a bar 14x14 cm. And then, on its plot, be sure to prepare a storage space Such a bar and its processing.

By the way, today many put even an ordinary bar in the wooden overlap on the edge. The fact is that even a ruler, from what kind of material it was not, it is easily bends along the entire length, but if you put it by an edge, it will be impossible to bend it almost impossible:

And on the draft floor from the boards, the clean floor is already installed, and then mounted the suspended ceiling. But often the wooden overlap of the attic is left without additional finishes specifically, due to the concept of interior design, but then all parts of it are performed very neatly and even with a decorative slope:

A certain rigid ribbed overlap gives the suspended ceiling itself.

Today there are several ways to attach attic beams. It is mainly necessary to install a perpendicular support beam, which is equal to the maximum length of the ceiling beams. If the project does not provide additional stiffebeals, then the beams of the attic overlap must lie along the axes of the racks of the bearing walls. According to standards, the beams of overlappings should be based on the upper strapping of the walls and is attached to it by two nails 3.5x100 millimeters on each side.

But often in construction it is necessary to apply special fastening methods, and in order to have better deal with them, we have prepared high-quality master classes for you.

Design a wooden attic overlap must be based on the loads that will affect it. But consider such a moment. Quite often, residential buildings are built with the calculation that they will be enough for the whole family. And such loads are divided into distributed and focused.

When designing a thoughtful overlap you need to consider precisely distributed loads, and you can learn more about them from modern SNiPs. Concentrated loads need to be taken into account only if you are exactly going to install some objects with a large mass in the attic.

For example, today it has become fashionable to arrange under the roof SPA salons, billiards, dance sites and rooms for music training. But in practice it is often it turns out that 10 rooms in the house are not enough. And under the roof - wonderful ventilation, beautiful space and quiet to equip your personal account there.

The need to use special fasteners depends on which technology of the arrangement of the attic overlap you chose at all. So the most reliable way is to drink beams on the bearing surfaces of the walls or on the beams of overlapping. Then there is no need and makes no sense to use metal elements - beams are mounted with self-draws or nails. In all other cases, it is necessary to secure the attic floor.

Therefore, we advise you to initially make such a strong attic overlap, so that in a couple of years with a calm conscience, rebuild it into the attic. And special calculations will help you to make our special tables and computer programs. Your task is to correctly select the optimal section of the beams and their step. Everything else - already the details.

Is the reinforced belt required?

First of all, decide whether you need Armopoyas to set the caustic overlap beams. Armopoyas is a reinforced belt, which is a closed design over the entire contour of the building. The task of such an element is the distribution of loads.

When installing wooden beams of the attic overlap, it is necessary to establish Armopoyas only if:

1. The walls of your home are built from a gas block or foam block. After all, such a material has a rather fragile structure, and the wooden beam overlap at the same time has a considerable weight. In view of its design, it always creates point pressure on blocks. And our task is to distribute this pressure and make it linear. So that Mauerlat takes over all load.
2. Also, whether prefabricated FBS blocks are followed as a foundation for your home, or the base is finely breeded, it is also important to correctly distribute the load from the attic over the entire base of the house.

In all other cases, you can safely do without Armopoyasa.

Fastening beams to bars or cut

When the beams of overlapping are attached to a cut or rounded logs, it is easiest to use frying technology. In simple language, simply insert the beams into the walls as part of the designer.

Please note that overlapping beams are fastened with metal brackets:

Fastening to a metal heated beam

If you have to break the beams of overlapping in length, then their parts should be connected to the flashes or with the help of special linings, and the struts are also needed between the beams themselves.

And if we are talking about the layout of a large area, then as a support for beams, it is better to use a steel 2-way beam or a particularly strong out of glued wood. In this case, there is a clearance of 10 millimeters between the attic beams and the steel dial beam. At the same time, it is important that the steel beam does not touch the ceiling lifting. And so that in the future the beams of the overlap did not creak, put additional soundproofing material or make the ceiling lamp quite dense:

If you use auxiliary beams, they are not at all necessary to place inside the overlap. Such can be easily embedded in the wall or even use yourself. And the beams themselves should be attached to the so-called beam shoes:

First of all for such beams you need to make a strapping. And at all, it is not necessarily the strapping itself to fasten to the walls of the first floor, as many people think.

The main thing is to properly prepare such beams to install. And for this, they should be treated with an antiseptic (and at a temperature not lower than 5 degrees of heat). Next, leave them to be soaked for a day. Now cut and lay such boards and supporting beam on a wooden mauelalat, pre-impregnated with flame-friendly. It remains only to consolidate all the beams of overlapping on the shoes.

And when the overlap from the beams will be ready, make a draft floor, at least in order for it to be comfortable to move.

Mounting to brick walls

If we are talking about fastening a wooden beam onto a brick wall, then you need to create a nest, and at the stage of the construction of the walls themselves. The socket must be 160 mm located inside the wall (this is at least), and on a special board.

By inserting the beam into the wall, you need to pour it with cement mortar or leave open - everything here depends on the thickness of the wall:

• So, the closed option is necessary with the thickness of the wall in two bricks.
• Outdoor - with a wall thickness in two and a half bricks.

In addition, the beam overlap of the attic when brick walls need to be increased by anchors, in each third beam. Anchor should cover it from below and on the sides, and in the wall themselves to go for 30 50 millimeters. An option is also possible to connect beams with each other and on the interior walls.

Fastening the beams to the brick wall follows this technology:

Fastening to fragile walls from blocks

If you are creating wooden beams in a block wall, then you need to build a reinforced concrete jumper. This is the same reinforced belt that we spoke before. It is necessary to arrange it under the beam, specifically under a wooden box that enters the wall. The beam itself will need to be installed on the reinforced belt in the wall, too, at the minimum 160 mm. And do not forget also about such an important point as the insulation from the block side and the gap from the beam, which will provide moisture output.

Therefore, that modern light blocks sustain the wooden beams of the attic overlap, follow this scheme:

If the blocks are quite durable and in their physical qualities is close to brick, then use such installation scheme:

If you smoothly approached the question of the devices of the attic overlap, the first problem with which you have to face is to search for good quality boards. It is very important that neither the beams, no sexual flooring had any flaw, were not weakened and certainly did not hurt any mold. Otherwise, such overlaps are dangerous for life for the life of households.

Option # 1 - Beams from ordinary boards

Let's separately note which beams need to be used when the attractive overlap device. Best option - boards 20-30 centimeters width. Pine or larch is taken as the material, which work well on the deflection. It is such a wood that is durable in terms of deformation and is less susceptible to cracks. According to official estimates, when applying such a material, it turns out to reduce the consumption of all wood by as much as 20%.

Option # 2 - Boxes of glued timber

The glued bar is also often used as beams, the strength of which is several times higher than the strength of ordinary wood. The thing is that any glued wooden products are stronger. The whole secret is that glue, which is used, falls into the pores of two glued parts and forms many strong threads between them - much stronger than the fibers of the wood itself. And therefore, the glued bar as the beams is quite normal.

In appearance, they do not differ from massive wood, especially when for aesthetics in the outer layers they use the best grade wood. Such beams are made of boards-lamellae, which is cleaned of defects and glued together. The main advantage of this method is that the total length of the beams can now reach 12 meters, and it will be much stronger, just with a wooden beam with the same parameters.

Option # 3 - beams from OSB

To make strong beams from OSB plates, they are cut into stripes of different widths and milling. Next, the billets glue with each other, and they form a long infinite strip from which templates of a certain length are made. The main advantage of using such beams for the devices of the attic cessation is a small mass and excellent indicators of strength and resistance of bending.

Option # 4 - I-beam beams

Another view in Russia, the type of beams is foreign. It is one of the most durable types of beams, and any flooring can be arranged on top of them, and not just Faneru. And the drywall is mounted below. These beams are so durable that they are more appropriately installed as a seating overlap for fully residential rooms, not only for attic and especially for a cold attic.

Also popular is also the so-called Canadian 2-way beams. They are manufactured in the factory conditions from wooden bars, OSB plates, special moisture-proof plates, glued timber or coniferous wood.

Option # 5 - Boxes of finished farms

For example, one of the most recent developments is ready attic farms. Their height is 350 millimeters. They are made of dry wood with a cross section of 100x50 mm. In the factory conditions on a special press with metal plates, such elements are connected in one design. Moreover, in the process of manufacturing such farms inside them, they even place engineering communications.

Option # 6 - LVL beams

Separately, it is worth noting that relatively new material on the domestic market - LVL beams. These are high-strength homogeneous materials that are manufactured by gluing under special pressure. Several layers of veneer are taken into consumption, and in the process of manufacturing bars, the fibers are located strictly in parallel.

Characteristics of such beams are special. The main advantage is that which beams have a large size of the sizes. The material itself is perfectly handling practically any cutting tools. But given the price on the LVL timber, we advise you to acquire it only if your attic overlap is located above the large span and for you in priority - quality and safety.

Option # 7 - HTS-beams

Another new kind of attic beams is German HTS. They also constitute a foreign one, where the upper and lower layer is from wood, but the middle layer is made from the OSB plate.

Between these layers, a sheet profiled steel with a thickness of 0.5 millimeters with a special polymer coating can also be inserted. At the same time, the steel itself has a wavy shape, so that the beam has high supporting characteristics. And there may be even one such walls, but two, which is even better for resistance to bend. And so that the hts-beam does not bend and not twisted, there are hidden transverse links between layers with a certain step.

In order not to dig a cold attic in the winter, you need to insulate the attic floor overlap. Do not warm the attic if it is not used for its intended purpose.

In order to solve this issue, you need to think about how to insulate the attic with the help of modern building materials. The process can occur both from the inside of the room and from the outside. Insulation is performed in the process of complex repair before final finish.

Even if the attic was not insulated during construction, you can always do this issue, and to carry out additional work.

Features

Most of the warm air masses go through the roof. Therefore, when the house is erected with a laptile attic, you need to carefully approach the topic of insulation of the attic ceiling with wooden beams. After all, it creates a certain barrier between warm rooms and a cold attic room.

Consider the special criteria of thermal insulation attic that affect the preservation of temperature in the house:

• Purpose of the room. The attic is a kind of buffer between the environment and the lodged rooms. Its task is to adjust the temperature difference between the external environment and the house.
• Temperature mode. In any season and any day, the temperature of the air masses in the attic will always be higher than outside the window. That is why in winter in the attic very cold, and in the summer it is unbearably hot and stuffy.
• Heat loss in winter.The more the substance heats up, the less dense it becomes. This is a physical phenomenon. That is why in residential areas with a heating system warm air from home appliances, focuses in the ceiling area. That is, if you do not insulate the ceiling, then in the winter period, all warm air will warm the attic.

• Excessive heat in summer.In summer, you can observe the reverse process. The roof rays of the sun, will warm up the attic air, which, in turn, will penetrate into the room through attic floors.
• Reverse aircraft cycle.Contact with the ceiling without thermal insulation, warm air becomes cold, more dense and, as a result, lowered to the floor. This is reflected in the residential premises in the form of walking drafts, which cause harm to human health.

• The appearance of excess moisture. In contact with a laptile attic, the wet roast air turns into condensate. The overall level of humidity in the house increases, which leads to the emergence of mold foci in the corners.
• Saving. The heat that went through the roof without insulation is about 30%. This means that with the correct insulation of the attic overlap, you can save 30% of the fuel used. The use of air conditioner in summer will also be associated with less costs.

The ingress of warm air masses on the technical attic (non-residential) leads to negative consequences:

• Due to the mixing of warm and cold masses in the attic room, condensate may appear. Water falling on the surface can lead to the process of rotting wood on the beams.
• If in the attic heat, then the snow gathered on the roof will begin to melt. Water dripping, starts to turn into icicles. Forming on the drainage system.

Materials

In order to correctly pick up the appearance of the insulation for the ceiling, you need to know several factors. The heat insulator should not only have a low thermal conductivity coefficient, but also have defined properties:

• Resistance to moisture and mechanical effects. The sealer should not change its form in mechanical loads. His qualities should remain unchanged, even in the case of wetting.
• Hemonslessness. The material should not burn and maintain burning. High temperatures should not have destructive influence on it.
• Low weight. To create a protective thermal frame, you need to select materials with a slight weight. Then the attic floors will not be subject to mechanical load.

• Ability to skip steam. In residential premises should be an acceptable temperature and normal level of humidity. To ensure this, you need to choose only vapor-permeable finishing materials.
• Environmental factors. The heat insulator is obliged to comply with all sanitary and hygienic standards. Hypoallergenicity and chemical neutrality are the basic requirements for the material. And it should not contain toxic substances and volatile connections.
• Mineral base.Insulation should not contain organic compounds, their base must be made of polymers. This will prevent the appearance of mold, and they will not bite the mouse.

Based on the foregoing, to insulate the attic wooden structures, there are several popular types of insulation:

Mineral insulation

Mineral wool is manufactured in two types - rolled and matte. It is performed by melting rocks at a very high temperature. Basalt wool is the most suitable for insulation the attic. It combines all the properties of the heat insulator. Mineral wool is pretty light and fragile. To protect it from mechanical exposure (to sell, strip), wooden flooring is stacked over the insulation.

The best view of the insulation for these purposes will be a hard mat of a large density, on the one hand reinforced foil. It stacked foil down. At the same time, it provides a reflection of heat and possess vaporizolation.

Glasswater

Material production technology is very similar to the production of basalt wool. But molten glass is taken as the main component. It has good spring properties. But in this case there is a fragility. In terms of mechanical exposure, it breaks. Glasswater is cheaper than mineral insulation, so it will suit those who are limited in the budget.

But it is necessary to take into account that when moisture gets into moisture, its thermal insulation properties deteriorate. It is harmful to humans, since small windows wound out the skin and can cause irritation.

Bulk insulation

Ceramzit is rounded brown pebbles. They are made of certain types of red clay, which sinters at a very high temperature. Ceramzite has a very low thermal conductivity coefficient, since its structure consists of closed areas. Each pebbles are protected from moisture from entering the fact that there is a dense clay layer on its surface. Small pebbles of the ceramzite are able to fill out hard to reach places, hidden cavities in carrying wooden elements.

This natural mineral heat insulator is not susceptible to burning, there are no harmful substances in it, the mold does not start, and he does not like rodents.

Foam sheets

The thermal insulator with the polymer structure is made by sintering small spherical granules. Its standard size is 100x100 cm. Thickness ranges from 1 to 15 cm. Polyfoam is one of the available and cheap insulation. But at the same time possesses the lowest thermal conductivity coefficient. Since it consists of polymers, there is no organic organ in its composition. This means that it is moisture-proof, not subject to rotting, and mold is not formed in it. The heat insulator is not affected by fire, but in the conditions of high temperature, it begins to exhibit toxic selection and the risk of high smoke appears. By the cons of the foam can be attributed to the fact that, due to its closed structure, it does not miss the water vapor.

Polystyrene foam plates obtained by extrusion

According to the composition of the substances, they are the same as the foam, but the methods of their manufacture are differ fundamentally. Polystyrene foam is obtained by a hot extrusion method, when a prepared polymer mixture is passed through a special apparatus. The specific density of the material is higher than that of the polyfoam, its structure is porous and homogeneous. This leads to higher thermal conductivity. The insulation is strong and withstands a large weight load.

Polyentenylene with reflective foil

Construction title of material Penofol. This is a heater in the shape of a roll, made of foamed polyethylene, covered with foil. It can be combined with other types of thermal insulators, since it itself has a limited scope of application. The structure of closed pores gives a low thermal conductivity coefficient. Through polyethylene does not pass air, liquid, water vapor. Therefore, the foam is a good waterproofer. Foil plays the role of the reflector, that is, it returns warmly back to the living room. Its thickness from 3 to 15 mm.

Wood-chip sawdust for reinforced concrete slabs

This is, first of all, accessibility and low cost. They go as insulation for ceiling floors in the sheds, baths, household buildings. The method of application is the delabcing of wooden attic designs with a mixture of clay and sawdust. The method is though primitive but effective. Sawdles can be bought on the sawmill. Clay is also available in an accessible amount. To knead the solution is not difficult. With a small specific weight, the mixture is very solid, especially after complete drying. Therefore, the wooden floors do not load. The material is vapor-permeable, but due to sawdust can develop mold bacteria, and also this type of insulation love to spoil rodents.

Most often, the insulation of the concrete structure occurs at the minilate, minvata, chopped straw and opium concrete.

Scheme of work

First you need to prepare heat-insulating materials and tools:

• a hammer;
• hacksaw;
• plancock, chisels;
• drill and screwdriver;
• construction stapler;

• rule, roulette;
• ladder;
• wooden bars and boards;
• parobarrier;
• finishing material.

Decide which insulation will be used:

• mineral wool;
• polystyrene foam;
• sawdust;
• penophol;

• glass gaming;
• styrofoam;
• ceramzit.

Then you should hold installation work.

Montaja technology

Depending on the selection of the insulation, the laying method is different.

Mineral insulation

Vata is placed in three ways: cells, furrows and a solid layer. The choice depends on the degree of load. The best design is obtained from a solid layer. First you need to put the film of vaporizolation. It assigns water vapor, which is directed from the room into an attic room. The film is strictly strictly in accordance with the marking, the brass. Wooden structures should be tightly covered with a film, otherwise they will be charged.

In the second stage, wata stacked. This is a simple procedure, the insulation is cutting into stripes. When laying, you need to ensure that the insulation does not flip, and there were no gaps between the sheets.

Attic overlaps need to be hydroizing. Then put the draft coating, which will later be the base for the finishing finish.

Polyfoam or extruded polystyrene foam

Stop rigid insulation are quite simple. First you need to align the base, remove the irregularities, the differences on the floor. Put the cement-sand tie. Sheets are stacked between bars. If no one will live in the attic, then the insulation must be closed with a polyethylene film. And if the floor is operated, it is necessary to put OSB plates on the foam or pour the cement mortar with a screed.

When insulation, the house must necessarily pay attention to the laws of physics. According to them, the air heated in the premises will rise to the ceiling. If the attic is not insufficient enough, then the heat will be disturbed outward, and the whole process can be called heat loss.

In order not to damn the street and save more heat in the house, it is necessary to carry out the heat insulation of the overlap. If you still do not know whether to do these works, it should be taken into account that through the roof and leaves in a volume of 25 to 40%. These data are particularly relevant for houses with a cold roof.

The heat insulation of the overlap will be performed immediately three functions that are needed to create a comfortable microclimate. The material will sound insulating, which will allow you to preserve the silence of the house during the wind and rain. In winter, the insulation will exclude heat loss and through which the heated air freely comes out. The thermal insulation is needed in the summer heat, because with its help you can create a barrier on the way of heated air. Even in the hottest weather inside the house will be saved.

Selection of material

If you plan to engage in the insulation of overlapping a cold attic, then you need to understand the variety of materials. The option of the insulation that you choose should be able to undergo a wide range of temperatures ranging from -30 to +30 ° C. It should not be wrapped under reduced temperatures and highlight harmful substances when heated. It is important to purchase fire-resistant heat insulation. This is true for electrical wiring.

It is better if the insulation is moisture-resistant, so as not to lose its properties during wetting. It should not be quickly lifted to fulfill its destination as long as possible. The insulation of the overlapping of a cold attic can be carried out rolled, slab or it is true for the floor of wooden beams. Whereas if you have to work with concrete slabs, you should purchase bulk or slab materials.

As mats and plates today are issued:

• styrofoam;
• seaweed;
• mineral wool;
• extruded polystyrene foam;
• straw.

As for rolled insulation, they are offered for sale in the following varieties:

• stone wool;
• mineral wool;
• glass gaming;
• frames from algae.

Choosing bulk materials for insulation overlapping a cold attic, you may prefer:

• ceramzit;
• reed;
• straw;
• buckwheat tyrsa;
• ecoWhat;
• sawdust;
• slag;
• peluons of foam.

Features of insulation mineral wool

Using basalt wool

The basalt insulation is made of gabbro-basalt rocks and acts as an optimal option for the heat insulation of the ceiling by the attic. The fibers of this material are more plastic, so they are not so stronger. They are well pronounced in mats that have sufficient strength.

Solving the insulation of the overlapping of a cold attic basalt cotton car, you receive a material that perfectly copes with the effects of external factors, therefore it can be laid on the side of the unheated room. The insulation is implemented in plates or rolls that may have different density. Sometimes one of the sides is a foil layer, which is capable of strengthening the insulation effect, because the heat will be reflected in the room.

About the harmfulness of mineral wat

In all mineral wats there is one common drawback, which is expressed in a binder consisting of phenol formaldehyde resins. During operation, they are constantly standing out into the air, which can be dangerous to human health. Therefore, it is impossible to consider this thermal insulation completely environmentally friendly. Basalt wool is stacked on the same principle as mineral.

Use of extruded polystyrene foam

Polystyrene foam, which is also called foam, is not very dense material. It can be used in the case when the floor is performed from beams and lag. The extruded polystyrene foam is stronger and dense than the usual foam. Before it laying the surface is aligned.

From the warm side of the floor, steam barrier to lay no need, because concrete slabs almost do not have the ability to vapor permeation. The insulation of concrete overlapping of a cold attic involves laying a vapor barrier film. The following layer becomes insulation plates, which are located in a checker order. Shakes are filled with mounting foam. As soon as it dry and hardens, the canvas are flooded with a concrete solution with a thickness of 6 cm. After drying, it can be used as a floor. On the surface you can lay outdoor coating.

Using Polymplats

If you insulate the attic room, it will not only increase the duration of the operation of the rafting system, but also roofing, and will also increase the level of thermal protection of residential premises under the attic. The insulation of overlapping a cold attic to the penplex came to replace other technologies that were used in construction quite widely. In this case, we are talking about the use of glass gambles, ceramisit and sea grass.

Modern selection - "Penoplex panel"

In the conditions of the countryside, the floor of the unheated attic is still insulated with clay and wood chips. Today, the "Pesoplex-Panel" is presented today, which is specifically designed for cold attics. If we neglect the work on the insulation of the room above the residential space, then this can cause the wetting of the insulation, which is due to condensate. Sometimes under the appropriate conditions, the construction of the roof and is at all starting to collapse, which is especially important with constant dampness.

Is it worth using a metal fastener

When the sex of the attic is not insulated, the icicles are constantly formed and flooded. It was mentioned above for large heat lines, they are caused by a weak level of heat shields. Developing a cold attic overlapping warming scheme with a fastener, you must take into account the features of how the flooring nodes with thermal insulation will be shown. The manufacturer does not recommend using metal fasteners, because they contribute to the formation of cold bridges, which reduces the level of heat shields.

To create a heat insulating cake on the overlap, the leveling screed is placed. Next covers vapor barrier in the form of polyethylene. The next layer will be the penplex. We should not forget about the presence of a separation layer in the form of polyethylene. At the last stage, the cement-sand screed is poured.

The insulation of the overlapping of a cold attic may provide for work with a sheet material in the form of plywood or OSP. In this case, vaporizolation, wooden beams and insulation Painopyx are stacked on the surface. It can be covered with a leaf material in the form of a GVL or CSP.

Finally

The insulation of a cold attic of the software allows you to create the boundary between the cold and warmth. Due to the formation of condensate in the field of the pile of the attic arise appropriate conditions that can contribute to the impressive heat loss. Proper ceiling warming allows you to create a barrier with a low degree of thermal conductivity.
