Why and how to warm the roof from the inside: detailed instructions. Correspond's insulation, how to close the roof circuit and the walls are insulated by the roof

The insulation of the roof of a tree house is one of the key stages of construction. The roof is more than other structural elements are exposed to the environment, so without high-quality isolation about comfortable accommodation in the house you can forget.

The lack of high-quality insulation allows the cold to freely penetrate the living quarters, so the cost of heating in the winter period increases to incredible values. To avoid these problems, you need to know how to insulate the roof in a wooden house with your own hands and what materials to choose to perform work.

Why do you need to warm the roof?

Beginner masters of the target of the insulation of the roof are not entirely understood. At first glance, this is not a prerequisite at all, especially if the attic room is non-residential and used to store unnecessary things. In such cases, an air pocket is formed between the roof and rooms, which is capable of delaying cold air flows.

In addition, wood has relatively good thermal insulation properties, therefore, carry additional insulation costs optionally. This is a common delusion.

Note! The main reason for the warming of the roof is a decrease in heating costs in the winter.

Of course, the air pocket in the attic will not give the cold air to penetrate inside, but also does not create obstacles to the exit of heat from the residential premises.

Temperature differences lead to formation on the inner surfaces and condensate rafters. Permanent moisture and dampness - a favorable environment for the development of fungus and mold. These malicious microorganisms are capable of turning the reliable house in a short time in a dilapidated design. It is noteworthy that it is almost impossible to remove the fungus after its appearance on wooden surfaces.

The key step of the roof insulation is the selection of heat-insulating material. It is necessary to deal with what options for the purchase can offer a modern market.

Selection of insulation

It is noteworthy, but when choosing a suitable material, it is necessary to take into account not only the heat insulating ability. The insulation should not contain and highlight toxic and chemically active substances. He must keep the form well and not deliver problems when processing and laying. Moreover, thermal insulation should not create loads on the supporting structures. In private construction, several types of insulation are used.

Mineral wool

Minvata is one of the most affordable and common insulating materials of the Russian construction market. It is produced in stoves or rolls, has a fibrous structure that reliably isolates the inner space from the sounds of the street. The advantages of mineral wool are that the material is resistant to temperature differences, does not support combustion, does not attract rodents and other pests. For insulation, do it yourself the roof of a wooden house from the inside this is the best option.

From the disadvantages, dependence on the wet environment and the need to install the root. If the attic will be used as a residential attic, a part of the internal space is closed after the work.

Ceramzit

This is a porous stone of artificial origin, which has excellent thermal insulating properties. The material is convenient in the installation and does not create load on the bearing structures and the base. However, the clamzite is more suitable for the outer insulation of the roof or walls, is used for the floor. To create high-quality thermal insulation pie, it will take a rather thick layer, which increases costs.

Polyfoam and expanded polystyrene

Both materials are made of polystyrene granules and possess external similarity. The insulation is produced in the form of plates that attract the attention of developers with a small weight and simplicity of installation. The difference between the foam and expanded polystyrene is the production technology, which involves various characteristics and properties.

The foam is obtained by treating polystyrene polystyrene granules, which connects individual particles to each other, forming a porous structure. The polystyrene is created by extrusion method, which gives the material higher density.

Both variants are neutral to the effects of a wet environment, have specific low thermal conductivity. Having preferred foam or polystyrene foam, do not forget that the material is lit, attracts mice and rats, can turn over time, creating gaps in the thermal insulation of the roof.

Liquid polyurethane foam

This is a modern appearance of the insulation, which is stacked under pressure in liquid form. Due to such a structure, the polyurethane fill evenly fills the free space, forming a monolithic heat insulation of the roof or walls without cold bridges. The non-flamm material does not create additional loads on overlapping and neutral to a wet environment.

The disadvantages of liquid polyurethane foam can be called the impossibility of independent performance and the cost of the material. However, the last nuance is justified by the durability and quality of thermal insulation.

Technology

Contrary to popular view, insulation is better not to do in the construction process. After completion of the work, the house is exposed to shrinkage, which can provoke a minor deformation of all structural elements. As a result, ruptures appear on the surface of the heat-insulating cake, which adversely affects the quality of the work performed. Professional builders recommend waiting for about a year and only after that heating. The process can be divided into several stages that require detailed consideration.

Preparation

Independent warming of the roof of a wooden house begins with inspection of all structural elements. This is especially true for old buildings where the roof flowed. In the process of inspection, it is necessary to pay attention to the sent areas, which are noticeable traces of rotting or fungal disputes are observed. Such elements are cleaned and processed by special compositions, if necessary, a complete replacement is carried out.

Negregate this rule is impossible. With the mass of indisputable advantages, wood is very dependent on the wet medium, so if there are traces of rotes, it does not make sense to fully eliminate such phenomena to the thermal insulation. The dampness gradually destroys the rafters and overlap, which at least lead to a disruption of the thermal insulation layer.

Important! Ideally, with the insulation of a wooden roof, an antiseptic need to process all the surfaces, paying special attention to the plots, closely adjacent to engineering communications.

About the benefits of hydro and vaporizolation

It is no secret that high-quality thermal insulation is a multilayer pie, where each element performs a strictly defined function. In the standard version it looks like this:

• waterproofing;
• doom (as needed);
• insulation;
• vaporizoation;
• finish finish.

The first layer is stacked waterproofing. Here you can use an ordinary polyethylene film, which will be perfectly cope with its task - protects the insulation from the effects of dampness.

Note! With long-term contact with water, even neutral to the entire foam begins to absorb moisture.

Osasurement leads to the separation of compressed granules with the subsequent destruction of the insulation slab. Fasten waterproofing directly on the base, fixing the construction stapler brackets to the rafters. If the budget allows you to purchase a superdiffusion membrane with a reflective layer. This is an expensive material, but it decides at once 3 tasks: protects against moisture, reflects thermal energy, creates additional warming and sound insulation.

Thermal insulation is then stacked. The recommended thickness of the insulation layer varies within 10-25 mm depending on the climatic characteristics of the region. Ideally, the insulation is a dense layer fills the free space between the rafters. In the upper part of the roof, a small ventilation gap is usually left, which will ensure air circulation and prevent condensate inside the heat insulating cake. We add that if mineral wool is used as a heater for the roof, it cannot be closed with electrical wiring.

The final layer is stacked by vaporizolation. This film, which is intended for detention of warm, oversaturated air moisture, rising from residential premises. It is also possible to use polyethylene, whose joints are sampled by building tape. If the work is performed correctly, the insulation is in a kind of waterproof cocoon, while the remained ventilation holes do not prevent the natural circulation of air. The finish coating is stacked over vaporizolation.

Finishing stage

If the attic will be used as a residential or utility room, it is recommended to perform insulation of the floor. Works are performed according to such a scheme:

• close up all the cracks between the beams;
• parosolation is stacked;
• installation of insulation, usually minvat or foam;
• falling asleep layer of clay;
• poured a screed.

Outdoor coating, such as linoleum, boards or laminate, is placed on top of the base.

Secrets of outdoor insulation

The heat insulation can be placed from the inside or outside. Each of the options for holding work has its advantages and disadvantages.

For example, if the thermal insulation is placed on the outer surface of the roof, the dew point shifts towards the street, therefore, you can not be afraid of condensate. However, the execution of such works directly depends on weather conditions, and only high-quality and, consequently, expensive materials are used for insulation.

between the roof lags are placed sheets of insulation or clamzit falls asleep;

waterproofing is stacked;

installation of the finishing coating is performed.

If a flat roof is insulated, the sheets of the insulation are arranged at an angle of 5-7 degrees with two layers. As the attachment, only special self-tapping screws are used with wide hats, so as not to urge the insulation. As a waterproofing, it is recommended to use pholoisol or bitumen-polymer compositions.

The insulation of the roof from the inside is produced not only to arrange an extra room in an attic room, but also to maximize heat conservation throughout the house.

If the building has an attic roof, then the insulation is carried out directly the roof itself, which is for the future room not only the roof, but also with the walls. If the design or has one slope, then most often the thermal insulation is arranged in the attic overlap.

The third option of developing measures is used in regions with a harsh climate, where they are insulated and the roof itself from the inside, and the ceiling overlap.

Types of insulation used

The modern building materials market offers quite a lot. types of insulation, of which You can choose suitable for any thermal insulation work.

• Bulk materials are sawdust, crumples of different fractions, slag, dry leaves or needles. These insulation are used for filling in an attic overlap, and they perfectly protect the lower rooms at home from the penetration of cold, but do not be able to make the attic warmly.

• Mineral wool of various types, polystyrene foam, foam and polyurethane foam are suitable for insulation of both attic floors and.

All these materials are sufficiently light, so they do not lose the roof design and the whole house, but will make it much warmer. Technology installation of thermal insulation materials differ from each other, so it is worth considering some of them.

It should be noted that with the advent of auxiliary materials that facilitate the work process and are aimed at protecting the thermal insulation from external influences and the preservation of their operational qualities, it became easier to carry out the installation process.

Parosolation coatings

One of these materials is a vapor barrier film. It is designed to protect wooden structures and insulation from the effects of steams arising from temperature drops and leading to the formation of condensate. Excessive moisture provokes the appearance of a mold fungus, which destroys the structure of the tree, reduces the thermal insulation characteristics of the insulation and contributes to the appearance of an unpleasant odor in the room.

A vapor barrier membrane is fixed to the design of the roof or overlap before laying insulation materials.

When using a pair-protective film in a heated room, it is placed only under the finishing layer of walls.

To protect the structures on which there are high temperatures on one side, and on the other - low, vaporizolation must be located on both sides. Such structures include wooden attic floors and roofing when it is insulation. Concrete slabs do not require laying of vapor insulation materials.

The protective film may have different thickness and be different types - the usual of the nonwoven material or the foil membrane. In the case of using the latter on the design of the attic overlap, it is filling the foil down, as it reflects the heat-rising from the bottom to the ceiling, thereby not letting it go out. Between themselves, the sheets of the material are fastened with a foil scotch, which helps to create a tightness of the coating.

Insulating films

Insulation of the attic overlap

Any insulation events are best carried out in the process of building a house, but, unfortunately, it is very often done only when you feel the winter cold.

Before falling down or laying the insulation, you need to prepare work. This is especially important if the grainzit of the shallow fraction is used, the sawdust slag.

• Previously, when there were no modern auxiliary materials on sale, the adhesive cartridge was prepared as follows:

- Boards, fixed to the beams of overlapping, thoroughly laughed with a solution of clay or lime having an average consistency in thickness. These natural materials create good overlap tightness, but at the same time - allow you to "breathe" the entire design.

- After complete drying of clay or lime, insulating work was made. Previously, it was mainly used slag, sawdust, dry leaves or a mixture of these materials. They fell asleep between the beams on the prepared boards.

It should be noted that the old traditional method is quite reliable, and therefore some builders even prefer it to modern and to this day.

• In modern construction, a special vapor barrier film is used mainly for flooring under the insulation. Its canvases are fully laid on the entire area of \u200b\u200bthe attic on-20 cm, deepening between the beams of overlapping and fixing on the boards and beams. The canvas between themselves are recommended to glue the construction scotch.

The film will be an additional obstacle on the way out of the premises of the heat house through the ceiling, as the heated air, rising up, not finding the exit, will fall and stay inside the house.

• Next, the insulation material is poured onto the film, the minvat is stacked, the clay is falling asleep, or the openings between the beams are filled with an emotory. You can use the insulation used earlier - slag or sawdust.

• To avoid the occurrence of cold bridges through wooden beams, they also need to fasten the layer of thin insulation.

• On top of the insulation, another layer of vaporizolation is labeled, as well as earlier - the braziness. This film layer is fixed to the beams of overlapping with rails, which are more often called counterbashers.
• From above the coating of boards or thick plywood is laid.

Sometimes vaporizolation can be fixed and inside the room to the wooden ceiling, but in this case it will need to be separated, for example, plasterboard plates. They level the ceiling and become another additional insulating layer.

Warming of roofing rods

When insulation of the roof rods, as well as when the overlapping is insulated, apply mineral wool and expanded polystyrene but mineral wool In this case, it is preferable because it has practically zero flammable.

If still it is decided to use foam plastic, it is recommended to purchase an extruded version. Although it has a slightly higher thermal conductivity, but it is not a fuel, and this is very important for wooden structures.

For the insulation of the roofing rods use different systems, but they necessarily contain a layer of vapor barrier material, insulation, waterproofing and a counterclaim.

1. This diagram shows one of the variants of the insulation "cake". It is used when building a roof and roofing flooring.

• The rafter system is stimulated. Usually, polyethylene is used for this layer, having a high density (with a thickness of more than 200 microns) - it will protect the root not only from moisture, but from the penetration of wind. The film is laid in 20 ÷ 25 cm and fasten it to rafters using brackets and stapler.
• On the top of the film for each rafter, a counterbasket with a thickness of 5 ÷ 7 mm is fixed. It is necessary to ensure that the roofing material does not lie directly to the waterproofing film, and between them there was a small distance for air circulation.
• Further, if the roof rates will be covered with soft roofing material, it is necessary to elect the phaneer from above. In the case when slate or other rigid sheet material is used, instead of plywood it is suitable, the width between its rails is calculated along the length of the sheets of roofing material.
• When the fence is ready, the roof is covered with the selected coating.

After that, you can move to insulation measures, which are conducted from the inside, that is, from the indoors of the attic.

• Between the rafter, mats of mineral wool or other insulation are stacked. They should most closely enter the elements of the wooden structure. Matte installation is produced, starting from below, gradually climbing the skate. The insulation must have the thickness of the same as the width of the rafters or a little less her, about 10 ÷ 15 mm.
• The underlined insulation is tightened with a vapor barrier film, which is fixed to racks. The film also puts the brass and gluits a construction scotch.

Last stage - Decorative decoration of indoor walls

• Further, if the attic room will be equipped with a living room, then the whole surface is trimmed with plasterboard or clapboard. In addition, in this case, in addition to the walls and the ceiling, the floors are insulated, that is, the attic overlap.

2. Another option may be a thicker insulating "pie", which also stacked immediately when the roof device.

• In this case, a waterproofing windproof film is also put on the truck system.
• Over top of it is satisfied with the roofing material.
• Further on the part of the attic, between the rafter stacked the first layer insulation that Must have equal rafal width.
• Then the transverse rails are stuffed at a distance from each other, equal to the width of the insulation of the next layer. In this case, the insulation is already used thinner. Its thickness should be equal to the thickness of stuffed transverse speakers.
• After that, there is a vapor barrier film that is fixed to the slats with brackets.
• The internal finishing material is then attached to the reikas.

If the roof is insulated in the already constructed house, where the roofing coating is fixed, then vaporizolation is fixed to the rafters on the side of the attic brackets, and only after that the insulation is stacked. Next, the process goes the same as in previous versions.

Insulation of the roof from the inside polyurethane

The insulation of polyurethane foam passes otherwise than bulk materials or mats of mineral wool and foam.

This method of thermal insulation has recently become increasingly popular and is suitable for both ordinary attics and attic, which will later become an extra room.

If the attic is ventilated, and the residential premises will not be arranged, then only the attic overlap is insulated. For this board and the beams are recommended to moisten for better adhesion, and polyurethane foam is sprayed on the wet surface between the beams. After foaming it, increase in volume and frozen, if necessary, another layer is applied. Such insulation will be quite enough to preserve heat in the house, as the foam penetrates all the cracks and hermetically closed them.

If the attic allows you to arrange a room on it on it, or the attic is an attic superstructure to the house, except for the overlap of polyurethane foam, roofs are insulated.

Spraying starts from the bottom of the structure, gradually climbing to the skate. A foam is sprayed between the rafters, and its lower layers, lifting and frozen, will be supported for the following upper levels.

A similar or attic creates a completely sealed uninterrupted space. Polyurethane foam will be well delayed heat inside the premises in winter and will not allow the attic to overheat in hot summer days. However, ventilation is still worth it, since the room must necessarily get air flow.

This type of thermal insulation has the following advantages over other insulation:

• Polyurethane foam coating does not have joints and seams across the insulated area.
• A significant reduction in temperature differences in the attic room and rooms on the lower floors are achieved.
• The building receives reliable protection against low and high temperatures affecting the house outside.
• Such a method of insulation shows a high payback in a very short time, due to the reduction in heating costs due to the low thermal conductivity of the material sprayed.
• When spraying polyurethane foam directly on the roof it gets extra stiffness and strength, since to a density forms reliable Communication with the entire roof design. At the same time, the polyurethane foam layer does not lead to the essential weighting of the roof.
• Convenience application - Pen It closes all the hard-to-reach places of roofing and overlap, penetrating all the large and fine holes and gaps, expanding and sealing the walls and floors.
• Polyurethane foam has high resistance to moisture, to the appearance Any forms of biological life, high and low temperatures, prevents the emergence and development of wood rotting processes.
• Foam gives not only excellent thermal insulation of the premises, but also well isolates from outside noise from the outside.
• Polyurethane foam does not give a shrinkage, not crushing and does not soften.
• The insulation has enough long-term service life, which is about 30 years.
• The material does not secrete toxic substances and unpleasant odors for the human body.

The following factors should be attributed to the "minuses" of sprayed insulation:

• The toxicity of the material when it is applied, so it is necessary to work using protective agents.

Not frozen polyurethane foam - enough toxic, so all work is carried out with mandatory leather protection, eyes and respiratory organs

• Polyurethane foam is susceptible to the negative impact of ultraviolet rays, so after applying the insulation, it must be closed with a finishing material, for example, clapboard, plywood or plasterboard.
• For mounting work on insulation, polyurethane foam must have special expensive equipment. True, if there are skills to work with this material, then the equipment can be rented. But in the case when this work is unfamiliar, it is better not to risk, but to invite specialists to sputter with equipment.

Warming attic and roofs are necessary for buildings in most Russian regions, therefore it should not be postponed this process "for later", and it is necessary to carry out thermal insulation work at the stage of building at home. Excluding the method of spraying polyurethane, all other insulation measures can be carried out independently, observing the technology of work. If you enlist the help of a comrade, then the insulation of the roof can be performed in a few days.

It has long been in Russia problems with the insulation of the roof did not arise at all: straw knit or the reed was dried, and all the roof of the house was securely protected from the rain, and from the cold. But modern coatings do not fully have thermal insulating properties, and with all the development of progress through such a roofing up to 30% of all heat breaks.

Therefore, if you do not want to warm the atmosphere, study in detail the warming of the roof from the inside - in this article we will reveal all moments!

Conditionally, the roof insulation in the construction world is divided into the attic when the roofs are insulated, and the attic when the overlap is insulated.

Like this? It can be said that the attic also have their attic - this is a ventilation gap between the inner insulation and laid roofing. The fact is that heat in all the laws of physics always rises up and looking for its access to the atmosphere. It passes through the insulation, and through vapor barrier, and with water vapors. And here in the cornice plumbing the outer air is pulled up, which goes to the skate and simultaneously picks up with them and the pairs and is too much warm. Through the aerators or the same horse, all this is safely displayed and does not cause any problems.

Those. At the usual, not used roof, the attic occupies all the place from the skate to the attic overlap, and at the mansarda attic is just a small space under the skates between the insulation and roofing coating. And in the insulation of both kind of roof - their approach, which we now and study.

Technology of insulation "Cold" roof

If your roof is cold, then the heat insulating layer should not be on the rods, but on the floor of the attic room. It is here that it stops the thermal stream going from below, and does not give cold from the roof to go down to the lower residential premises. As a result, the temperature in the attic is held within + 1-2 degrees, the roofing material is not heated. In fact, such an attic serves as the necessary air layer between the residential rooms at home and the thin overlap of the roof.

For attic overlap, all rolled, slab and bulk insulation are suitable. Because The overlap of the slope does not have a special requirement for the heat-insulating material used by him: it will not turn anything and take off.

Please note that after insulation of the roof in it, it remains properly organized ventilation: there should be auditory windows that are opposite each other, ventilation skates and aerators, and in the eaves - round-the-clock access for the outer air suction. As a result, the temperature in the non-residential attic room should be as close as possible to the street, and it already separates the residential premises below - the literate heat insulation of the overlap.

Now let's look in more detail with the insulation of a cold roof.

Warming Minvata.

When insulating the floor, the attic mineral wool, first of all, pay attention to the distance between the slats or lags - it should be slightly smaller than the roll or mat of the insulation.

Usually the thermal insulation of the inner space of the roof is complicated by the uneven surface of the floor of the attic, the differences of its height, a large number of rails and bars, not to mention the ventilation pipes and wiring:

Eco-insulation

If you want the house to breathe, and the pair easily went up, then insulate the attic overlap of modern eco-art:

Insulation of strangal wool

Recently, the bloutwork - the insulation of the roof of the polar car is becoming increasingly popular. The Japanese "insulation" of Esbro-Vul II, which does not distinguish between dust, is applied here, and therefore does not create problems. And the blouting method itself is clear enough:

• Step 1. We put the vertical line on the floor and mark the necessary height of the mineral wool sputtering.
• Step 2. We apply the insulation with a uniform layer to the desired level.
• Step 3. We put the insulation so tight so that on one cubic meter it accounted for 25 kg of weight.

Note that this type of insulation in Japan is the most popular, and has already found many supporters in Russia.

Warming glass gamble

And finally, glass gamble - if the attic you will not use at all. The fact is that even a glass wool closed under the crate sometimes causes irritation of ENT organs. Why and you have to work with her to wear a respirator and glasses:

Warming sawdust

When insulating the roof with sawdust, follow such instructions:

• Step 1. First you need to protect the wooden structure. To do this, we first apply the antiseptic composition, then flaky-protected mixtures, and on top of the hydrophobizers.
• Step 2. The next step is putting the substrate (you can cardboard) and close the seams and cracks, if there are such, foam (large) or sealant (small). At the end, cut the outstanding foam and equalize it with beams.
• Step 3. Now we fall asleep sawders, in two layers: first a larger fraction, as well as chips, and then - small so that dust is not formed in the room.
• Step 4. And so that the attic does not start rodents on the floor, in addition to the layout, mix dry lime and fine broken glass.

Technology insulation "warm" roof

An attic roof is a special design. Here, too, there is a cold attic, only it is completely small, because The insulated attic ceiling is almost close to it with the help of an additional crate. In fact, only space for ventilation remains, and no more. And the ventilation serves to ensure that the heat from the attic does not concern the roofing coating, on which the snow should remain as the heat insulator, rather than faster.

Here is a bright example of the most standard situation of misunderstanding: set the cheapest rafters of 15 cm, put a fluffy mineral wool in two layers of 5 cm and close it all with roofing coating. Ventilation - just 5 cm, without tributary and output, because There was no specialist next to suggest. As a result, in the summer - unbearable heat, from which even air conditioners do not save, and in the winter - generous on the roof. And all because the overall air is heated in this scheme. In other words, the smallest attic, about which we talked, must be, and far from 5 cm.

And especially carefully in such a roof, you need to think over vapor barrier:

And further. Material manufacturing rafters is always designed for some specific weight. So, the roof of a soft tile can also be built from the profiles for drywall, only it is impossible to warm it with a heavy basalt cotton car. Also, a native roof is needed good forced ventilation so that the insulation does not reveal and have not spoiled. Therefore, carefully read all the items of the Master Classes prepared by us:

Mineral wool insulation

Follow this simple instruction:

• Step 1. Install the hydro and windproof. If possible, use modern membranes - they are more durable and durable. In any case, fasten the material of the mustache, and all the joints are punctured by construction scotch.
• Step 2. Now let's measure the distance between adjacent rafters.
• Step 3. With the help of an ordinary or stationery knife, it is easy to cut the insulation to the desired pieces and insert between the rafters.
• Step 4. Installing an additional crate of the membrane and internal facing.

Please note that mounting a vapor insulation membrane is needed by a smooth side to the insulation, and the darling - already inside the room.

If the distance between the beams is not more than 60 centimeters, it will be more convenient for you to use the square mats of the insulation:

• Step 1. Inside, under the rafter, it is advisable to finish a draft crate - so that the insulation was to rest on. Distance between Brucks make about 20-30 cm. For this purpose, the usual uncircumcised wood with nails of the average value is fully suitable, it is important only that the bars are the same thickness.
• Step 2. After installing the draft crate inside the design, remove all dust and dirt with the help of a building vacuum cleaner.
• Step 3. Next process all the wooden specialty from fungus, rot and mold. Just use for this purpose not a bullettor, which is less effective, but a conventional painting brush. With its help you can achieve deep penetration of the product in the wood, and this is important.
• Step 4. Let us finally absorb and dry the medium for two or three days.

As a result, you have all sheets must lie tightly - a little more dense than you need at first glance. Only so you can avoid the presence of cracks and the subsequent freezing of the roof.

And one more point: ordinary mineral wool slabs are not too meant for the insulation of rods, because It is bad to hold between the rafted, but you can warm the frontoths.

Warming glass gamble

For the insulation of the roof rods, it is best to get the best, from well-known manufacturers. Such a glass gamble practically does not contain a dangerous fiberglass, which most just annoys the workers. She also after laying does not emit harmful substances, which is even confirmed by the Finnish Institute of Health. After all, one thing to quit this "bar" to overlapping an unused attic, and another thing is to cover with the clapboard in the billiard room or personal office on the attic floor.

Combined insulation

If you wish and appropriate, you can warm the roof from the inside, two different types of insulation simultaneously. But it is necessary to consider one important point - vapor permeability. The fact is that selecting different insulation for an effective combination, we usually only summarize their heat insulating properties. But the paropropusk ability they have completely different!

And, if you, for example, put down when insulation first by the Minvatu, and on top of the foam, then the water vapors falling into the cotton will begin to strive for a colder part of the roof and burst into absolutely disturbing foam. As a result, all the insulation will simply fall and "delight" mold. But on the contrary - you can: first put the foam on the bottom of the rafter, and already mineral wool on it. If some steam passes through vapor barrier and cracks between foam plates, it will easily overcome the Minvatu and gets into the ventilation channel. Therefore, there is such a rule: the upper layer of insulation should always have greater vapor permeability and thermal conductivity.

And finally, if the warm roof will be used as a sauna or an extra bathroom, insulation and roofing pie should be thought out especially carefully.

The insulation of the roof from the inside is the optimal version of the work for several reasons.

The roof insulation is made only for residential attic rooms, due to this, thermal losses are significantly reduced and the comfort of accommodation increases. Today, companies produce a large range of materials for insulation, everyone has both positive and negative sides. During the choice of a particular insulation, it is important to know its features and take into account the characteristics of the rafter system of the building.

The names of materials for insulation are many, but they all are divided into two large groups.

Table. Insulation groups for roofs.

Name of insulation	Operational and physical characteristics
	This group includes mineral wool from basalt, glass gambler from secondary glass and eco-water from waste paper. Wool insulation can be pressed in the form of standard dimensions or rolled mats. There are options for spraying liquid eco-water. In terms of thermal conductivity and weight, these species are almost no different from each other. More than all mineral wool.
	Polyfoam, polystyrene foam, polyurethane foam, etc. All these insulation are manufactured on the basis of the same polymer, differ in production technology and some additives. Most often have the form of plates of various thickness and sizes, can differ significantly in terms of physical strength. Heat conductivity is almost the same, minor fluctuations in practice do not have any influence. Large price variation. Can be used in liquid form (sprayed) or as a stove.

For example, we will look at the two most common options for the roof insulation from the inside. Examples are not only budget, but also effective. The process is divided into several stages, the final quality of the work depends on the correct execution of each of them.

Inspection of the rafter system and roofing

Very important stage of preparation for insulation. Make the revision of all elements of the roofing system, check the condition of the roof coating. If you find problems, they must be eliminated immediately.

Measure the distance between rapid legs, it will help to navigate with the choice of insulation. The fact is that all insulation have standard size in width. At the expense of this, installation works are simplified and accelerated and the amount of waste is reduced. Width of heaters 60 cm, but, unfortunately, some manufacturers allow oscillations in one direction or another to several centimeters. The distance between the rapid legs should be within 56-57 cm. In practice, it is rare to find such regular roofs.

Look, whether it is installed between the roof and the attic room of the windproof, whether it has products for natural ventilation. This is very important in cases where insulation is planned to make mineral wool.

Choice and purchase of materials

The most commonly used materials for insulation of the roof - mineral wool and foam, it is on them that we will stop in detail. If you have a simple two-tie roof, then its insulation is not very difficult technologically. A completely different situation with a broken or four-sheet roof. These designs have many different stops, runs, screeds and other elements that enhance the solo system. During insulation, there are minvatu or foam foam, make various podgibs and bends. As a result, the complexity of the work increases and the amount of waste increases.

But this is not all problems. Complex roofs will never be able to hermetically close the vapor barrier layer, there will always be places, through which humid air in the insulation falls. For mineral wool, this is a very unpleasant phenomenon. Experienced builders recommend complex roofs to insulate foam, and not risking with minvata. Wet wool not only almost completely loses its heat-saving abilities, but also speeds up the penetrating processes of the wooden structures of the rafter system.

Roof warming work

The technology of work largely depends on the selected material, but for all cases there are general advice.

If there is an opportunity to work with an assistant - excellent, the process of insulation will go much faster. There is no such possibility - nothing terrible, all work can be done independently.

Not a simple knot, as a rule, we often ignore as the roofers and facade. They are often bad, because it is closed with a stitched material, if not visible, why try. Let's figure out.

I imagine the last crown of the house boxes, the ends of the rafter legs are lowered for the perimeter of the well of the house, the pockets are formed between them, for the plug of these pockets they will push, on the knee a drink, and everything, the fit of the board is bad, put so that it would be, but In the case of insulation on the rafters, this node is the end of the wall and the insulation circuit along the rafters. Meanwhile, in this place, the walls and roofs always occur the processes of increased risk for example from the outside during the winter period, warm air from the open windows and from the inner side, this node is a leakage of warm air from the room with a poorly made vapor insulating circuit, which is ultimately The result leads to the formation of icicles on the cornice. And for a number of reasons.

Poor thermal insulation ceiling overlaps. Bad ventilation of the attic space. A roofing pie is incorrectly made on a warm roof. Natural factors during thaws. Incorrect operation of the attic space.

What I am talking about in this article is only one of the steps that this would not have happened to your roofs.

In fact, especially difficult, there is nothing, you just do not need to hurry and do everything neatly, carefully. Material is crucial with which you work and accessories, usually all adjoining glue and seal and best use materials and accessories of one manufacturer It will be a guarantee of long-term exploitation of nodes data.
