How to insulate the ceiling with screwdrivers. How to insulate the ceiling in a private house - options and review of materials

In the cold season, any house loses heat due to looting in places of joints building structures, slots in windows and doors, as well as due to thermal radiation of walls, floors and ceilings in the surrounding space. At the same time, the stake of ceilings and roofs comes from 15 to 45% of all heat losses. Therefore, the ceiling must be insulated, excluding heat loss due to the output of heated air and due to heat transfer. Most of the methods of insulation do not require expensive equipment and special qualifications of workers. They are completely on the shoulder to perform work on the warming of the house with their own hands.

In addition to the most important task - heat conservation - work on thermal insulation solve and one more - maintaining optimal humidity. For this, except for insulation materials, steamer and waterproofing membranes are used, preventing condensate accumulation on ceilings and walls. Semi-permeable membrane films passed through themselves into one of the pair of water and do not let moisture in the opposite direction.

General scheme of ceiling and roof insulation

Ceiling and roof insulation schemes

From the point of view of insulation, all roofs are divided into two types:

• Warm. There are several layers under the roofing material: vapor barrier, insulation for ceiling and waterproofing. They hold the crates - spatial structures that are fastened to the rafters. The attic premises ceiling is insulated according to such a scheme.
• Cool. Have a layer of roofing material and carrying the structure and the layer of pair-hydro insulation substituted under them. Aerial layer In the attic is an additional barrier on the way of heat loss. The ceiling located under the so-called cold roofmust be insulated and waterproof.

Features of ceiling insulation

The main feature of the insulation of a flat ceiling is the inability to arrange the flow of condensate, as they do for inclined roofs. Therefore, almost all warming decisions are aimed at removing the water pairs up, providing them with unhindered passage through all layers.

Cold overlap

How to warm the ceiling under a cold attic? Over the cold or heat-conducting overlap (for example, concrete) leave air gaps. The first, auxiliary between the vapor barrier film and the insulation, comes into effect at large temperature differences and abundant condensation. It should be well ventilated. The main gap between the insulation and the waterproofing layer is easier to make ventilated - it is enough to leave a small slot around the perimeter. Cold overlap is preferably insulated both from above and below. The insulation used for the ceiling under the cold attic must be moisture-resistant.

Warm overlap

Warm is called the overlap made from low thermal conductivity materials, such as wood. Such floors, by themselves serving the heat insulator, can only be insulated from above. Even if the condensate is formed with the temperature differences, it is absorbed into wooden structures, without changing their properties, and will later evaporate. As a rule, this process is invisible for the inhabitants.

Steam barrier is laid on the overlap without the gap, then the insulation is laid. The air gap between the heat insulation layer and the hydrobaric membrane should also be left and will provide the possibility of ventilation.

Materials for insulation

To the question of which insulation is better, there is no definite answer. The choice is determined by several factors, such as:

• thermal insulation properties;
• features of the ceiling design;
• price;
• requirements for qualifications and equipment
• availability of materials.

Materials for insulation are divided into basic and auxiliary. The auxiliary includes barrier and membrane.

Barriers and membranes

PARBAPERs

Parosolation barriers are needed so that water pairs do not pass through them. For their manufacture, polypropylene films are used with a thickness of more than 55 microns.

Polyethylene as a vaporizolyator is unsuitable - over time, it is cracking over time from temperature fluctuations and starts to skip the couple. However, if you solder the layer of polyethylene and a foil layer - it turns out high-quality vaporizolation.

The pholoisoles also provide a layer of fibrous nonwoven material of the type of synthesis. This layer collects moisture from the insulation and the capillars takes it to the side. With its availability, an additional air gap over the cold overlap can not be done.

Membranes

Multilayer reinforced membrane materials skip pairs in one direction and delay moisture in the opposite. The reinforcing grid layer ensures the strength of the film, does not allow it to be saved and guarantees the constancy of the magnitude of the main air gap.

Membranes with reinforcing layer

Membranes for laying under the roof have metallized outside. It increases resistance to weather conditions - high humidity, wind loads and temperature differences.

Insulation

What is better to warm the cold ceiling? The main thermal insulation materials used to insulate the ceilings can be divided into the following categories:

• Solid. Such materials consist of foam plastics, are little exposed to moisture, conveniently mounted.
• Fibrous. Mates or rolls are formed from compressed fibers. Inexpensive, have good thermal insulation. Sensitive to moisture, with wets lose thermal insulation properties.
• Bulk. Traditional bulk materials -, ceramzit, etc. The cheapest, possess weak heat insulation. Separately, EcoWhat is allocated - not cheap, but extremely effective material.
• Sprayed. Modern coatings of foamed plastics. They are spared at the place, do not form joints and seams. The best thermal insulation, very expensive equipment.

How to insulate the ceiling, each decides itself, based on its needs and opportunities.

Mineral wool

Rolled Minvata.

The most popular type of fibrous materials. Produced from several types of raw materials:

• Basalt wool from volcanic rocks. High strength and density, short rigid fibers. High moisture resistance.
• Glasswater from secondary glass. Low strength, light and elastic, long elastic fibers.
• Slotted from damage waste. Low thermal insulation properties, low cost. For residential buildings does not apply.

For the insulation of the Minvata, special equipment is required, the process of laying is simple and quite fast. Available in rolls and stoves of the insulation thickness up to 150 mm.

Mineral wool is harmful to health, during styling it is necessary to use the respirator, protective gloves and glasses.

Attention! If the fibers hit the mucous membranes, in the respiratory organs, digestion should be consistently console to the doctor.

After laying during operation, the mineral wool is completely harmless for living in the house.

An important feature of the Minvati, which should be taken into account when designing and laying, is a large number of joints and adjoints. They need to be carried out so that the gap is minimal, stove laying to the guides and to each other. Polusantimeter slots between the plates can reduce the coating efficiency by a third.

Proper and incorrect laying of insulation

The heat-insulating properties of minvats are reduced up to their loss during the wetting of the material. Therefore, it is necessary to ensure the diversion of vapors and condensate.

Monolithic

The most suitable and popular material for thermal insulation of ceilings is a polystyrene foam. It is made in the form of panels 1200 * 600mm, equipped with sheets. This allows you to make high-quality joints when installing. In addition, the gaps and gaps are compacted by mounting foam. Material racks to moisture and temperature fluctuations. Perfectly manifests itself with the insulation of the ceiling both outside and from the inside

The disadvantage of it is low fastness to fire. With burning, it highlights substances harmful to health.

Insulation polyurethane foam

Polyfoam, or foamed polyurethane, is significantly cheaper than polystyrene foam, but has low strength and prone to choking. Suitable for insulation ceiling from the inside.

Sprayed and bulk materials

Sprayed materials are very effective, do not have joints and seams, almost do not burn. They can be effectively sprayed into hard to reach places and cavities, providing thermal insulation where other materials can be placed only with partial disassembly of building structures.

The main drawback is the extremely high cost of equipment and high qualification of the operator. This is holding back the widespread dissemination of the promising method.

Ekwata.

Very promising both bulk and sprayed insulation for roofs and ceiling. It occupies an intermediate position between sprayed and bulk materials. It is made from secondary paper, thermal conductivity coincides with the Minvata. Fibers with the addition of glue are fed to the surface or to the cavity under low pressure and are frozen there. When wetting partially loses its properties, but after drying, they are returned.

Supplements in the composition of EcoWhat make it little combustible, environmentally friendly and unattractive for rodents and mold. The material does not cause allergies and does not contribute to the development of cancer.

Methods of installing EcoWati

Applying eco-art does not require special qualifications, and the installation is slightly complicated by a vacuum cleaner. One of the few drawbacks is the requirement for applying: not lower than +23 o

Ceramzit and crumb foam glass (Penolrochka)

When dripping with clay and foamin, it is necessary to take into account that its thermal insulation properties are small compared to more modern materials. Therefore, the layer will need significantly thicker.

Ceramzit - traditional bulk insulation

Few merits of the material - its cheapness, moisture resistance and non-causing.

Ceramzite is used in budget solutions, as an external layer, internal thermal insulation is performed. mineral Vata.

Scheme of two-layer insulation with clay and minor

Sawdust and chips

These materials can attract their cheapness, sawdust and chips on woodworking industries can be free. The chips possesses high fire hazard, sawdust is lit much worse.

Heat ceiling

Consider the process of insulation ceiling the attic of the Minvata. Technology differs based on specific designs and selected schemes.

Outside

The easiest I. fast way Thermal insulation is inter bat. If the ceiling is made of massive boards, vaporizolation need to circle around the beams or make the films of the film on them. If the ceiling is dialed out of thin lining or slats, the foil vapor insulation film is fixed below the beams, on the ceiling.

Methods of insulation wooden ceiling with attic

The complete insulation scheme requires significantly more labor, materials and time, but it is much more efficient. A scribal double layer of plates is added to the inter-bull layer from rolls or mats. Stop layers are needed with overlapping.

How to insulate cold ceiling from the inside

choosing a method of thermal insulation ceiling from the inside, you need to understand that any of them will reduce the height of the room. Minimum height loss will be in case of installation stretch ceiling or suspended ceiling of plasterboard. In this case, thermal insulation slabs can be laid between guide metal products.

Fastening basalt wool on plate dowels

If the suspension ceiling is not planned, the insulation plates can be fixed in various ways:

• Still making guides from wooden rails or metal profiles.
• Secure the panel with special plate dowels. On one mat size 1200 * 600 mm you need at least 4-5 dowels
• Printed to overlapping mastic.

The reinforced grid is glued to the lower part of the insulation, and the leveling soil and paint layers are applied to it.

Without attic

In case of insulation of buildings without a attic, in addition to solving the problem of actually conservation of heat, it is necessary to provide an overview of excessive moisture, as contained in the air in the form of vapors and condensing on cold surfaces.

Scheme for buildings without a attic

Parobarrier is laid under a slight ceiling, a layer of thermal insulation of the material is stacked on it. It is necessary to provide two ventilated gaps - between thermal insulation and waterproofing and between waterproofing and roofing material. Along the skate you need to arrange a product or just lift the lining of the skate so that the air can go out free.

Special cases

Consider a few special cases.

In an apartment building

Apartments on the last floors of apartment buildings are known as cold. Especially if the builders performed thermal insulation overlap with violation of technology. Any independent work In the attic of an apartment building is illegal, it is better to spend time on claims to a construction or operating organization and force them to fulfill their obligations to ensure normal temperature. But the complaint process is not a quick thing, and it is cold in the rooms today.

However, warming the ceiling quickly and inexpensively can be from the inside and cope with its own. We will have to "please" by the neighbors drilling numerous holes in the ceiling under the dowel, but the result is worth it.

Ceiling insulation in an apartment building

Another disadvantage will be a decrease in the height of the rooms by 4-5 cm, and around the perimeter of the ceiling - and up to 40 cm. But heat is more expensive.

On the warm ceiling A system of guides from wooden rails or a metal profile height is 4 cm. Between them lay foam sheets with a thickness of 30 mm and are attached to the ceiling on the plate dowels.

After that, on the lower edges of the guides, foil vapor barrier is attached. On the perimeter, the slope is performed by a radius of 40-40 cm, which provides a smooth pairing of the planes of the lines of the rash-brake and walls. At the last stage, the sheets of moisture-resistant plasterboard are attached. The curvilinear slopes fall asleep with a crumb of foam, starting with short sides of the room. Suitable for this and Eco.

Attic

The residential attic should necessarily be inspired. It will not hurt insulation and non-residential attic - it will be an additional barrier on the way of cold in residential floors. How to reliably insulate the ceiling on the residential attic? The most common scheme is insulation with minvati plates or polyurethane foam with styling between rafters. For vertical walls, you will need to take a special cotton wool with a low shrinkage rate.

Scheme of thermal insulation of mansardes

Special attention will need to pay vaporizolation. In the already built house, the steering space is not always available. In this case, it can be avoided - it can be blown through the temporary technological holes, which are further compressed by the mounting foam.

Garage and Banya

The roof of the garage is often kept on the metal beams of the 2-way profile. When installing the guides for the insulation, drilling holes from the bottom up in the steel beam is inconvenient, therefore the method shown in the figure is used. The insulation plates are placed in two layers with overlapping. Instead of fibrous materials, you can try EcoWhat. In this case, it is possible to do without folgic, and instead of it for a false-brace, sash kraft paper.

Mounting Schemes for Bath and Garage

A standard thermal insulation scheme is used for the bath. Increased humidity The premises require the use of basalt wool - the insulation of the ceiling of the glass container is not recommended. Special attention should be paid to the quality of the ventilation of the gaps. EcoWhat must be made with glue. If the bath ceiling is insulated by working on the side of the attic, often apply and bulk materials, such as sawdust and chips.

Employee skills and tools

Popular insulation methods do not require expensive equipment and high qualifications. For insulation homemade Master There will be enough general construction skills and conventional tools:

• a hammer
• screwdriver
• hacksaw
• step
• roulette

When installing guides, it is best to call an assistant. It does not prevent help and with stripping and laying rolled materials.

Before starting work and procurement of materials, it is necessary to make a sketchy drawing. This will help not be mistaken with sizes and correctly calculate the number of purchased materials.

Typically, the ceiling and the roof consume up to forty percent of the entire heat exchange house. The insulation of the ceiling is a question of a topical question for many families. For such work, we need certain knowledge and skills of the builder. As in any building process, here there are features and difficulties. Currently, thanks to modern technologies, any novice builder and a simple man will work such work.

Features

The so-called cold roof is built in several other principles. When it is erected, the usual types of layering of materials do not use. A similar species exists in those houses where the room under the roof is not residential and not heated in winter.

Due to such a structure of the roof, it has lightweight weight and minimal expenditures.The installation itself is much easier to perform than when building a roof with a warm design. It used to be thought that it was perfect and inexpensive option During the construction of a simple country house.

It is important to know that due to the absence of heating in the upper room, the air there performs the role of a buffer that helps to avoid unnecessary heat losses.

By increasing the tariffs for heating, many people began to think about the insulation of the ceilings. A large amount of heat evaporates from the house due to the presence of slots in the ceiling floors. This is due to poor-quality construction and bad building materials.

The ceiling insulation and the presence of a cold roof is a topical problem for residents of the last floors. This is especially true for the old housing stock. This problem is relevant for the owners who live in a private house. The attic is a neutral territory, and the management company may not allow the layer of the insulation there. Therefore, the option with the ceiling insulation is in its own apartment.

A feature of such a solution will serve that several useful centimeters will lose from the height of the ceiling. But due to the possibilities of plasterboard and various lighting devices, you can get an updated and trendy interior. To keep warm and pay for heating is not too much, it is worth thinking about the ceiling warming.

The thermal insulation of the ceiling in a private house has its own characteristics.Work is customary to start from the second or extreme floor. It may be an attic room, the last floor or attic area. Laying special material with thermal insulation properties It occurs on top of the overlap or in empty gaps and helps retention of heat in the room.

No need to think about the extra ceiling finish. The master will not need to be mounted insulation on the ceiling itself. Thanks to the placement of the insulation, condensate will not be formed in the overlap.

You need to know that it is impossible to insulate the rod of the roof. This will contribute to the melting of snow and the formation of icicles. In addition, the warmed attic on construction standards is already an attic. It is important to know about such a feature that the next layer directed from the room should be more parreroping than the previous one.

Another feature is that the condensate is impossible. This rule applies to the inclined ceiling. There are drained walls. It is very expensive and complicated pleasure for owners of a private house. Cool and hot side of the ceiling in an apartment building can change places. It depends on the time of year.

It is worth knowing that the modern technology of ceiling insulation is focused on the absence of condensate in the material itself.

And if he was still formed, he should have the opportunity to go out.

Another feature is the process of laying in cold overlap. When using loose material, it is necessary to leave the gaps. Another gap remains between the insulator and the insulation layer. This technique is a safety in the event of condensate.

In a private house or cottage, insulation the next floor ceiling is possible using a special material that is laying on top of the overlap or in existing emptiness. The features of the overlap depends on its type. It can be made of wood or concrete.

To put insulation on beams, which are a wooden floor, it is worth using lightweight and falling materials. Materials will fit well and in the form of a roll. In order to insulate the concrete, it is worth using not very loose mats and dense materials.

If the question of insulation was not resolved at the construction stage or we are talking On the last floor of a residential building, it is quite justified to start insulation as needed.

If we are talking about the insulation of the roof of a private lady out of wood, then in this case there are a number of advantages. Insulation will create additional sound isolation. This is especially important in moments of heavy rain and wind on the street. In the heat, the insulation will retain hot air from the street. Due to this, a pleasant climate will remain indoors.

In winter, the warmed roof will help to significantly save electricity and will be prevented from the outlet of the heat out of the room.

Warm the ceiling in a private house from a tree can be independently. It is important to prepare well. It is necessary to know the properties different materials, their pros and cons, own specific technology for ceiling warming, explore the video instruction.

It became fashionable to warm the attic and turn them into the attic. A feature of such a room is the criteria of ventilation area, which are located between the room and the outer construction. The size of such ventilation usually varies within fifteen - twenty centimeters. But the usual roof has an attic with auditory windows. Therefore, to create a warm climate there, it is important to take care of sufficient air circulation.

When heating good ventilation Reduces the heating degree of roof and prevents the formation of ice blocks on the roof.

For residents multi-storey houses Or private in the absence of the possibility of the roof insulation from the top floor you can consider another option. We are talking about insulation from below. This type of work is possible if the reconstruction of the premises with good overlapping In the attic, when there is no possibility to get into the attic room. This is especially true for residents of apartment buildings and non-promotional managers. In this case, the construction of a frame-based framework from wooden plates will be carried out or metal elements. Insulation can be in the form of plates.

With this form of insulation there is a big minus. As mentioned earlier, the height of the room and precious centimeters is lost at the expense of such a reception.

In addition, such works require more experience and time on their execution.

It must be remembered that good and durable isolation will turn out to be a comprehensive approach. In addition, indoors with a cold roof additionally need to insulate the door, window openings and in the mandatory floor. With the help of a thermal imager, you can easily calculate the sections through which the largest amount of heat leaves. Usually they are red and yellow.

Materials

Currently, building stores contain a large selection of insulation. To choose optional optionsIt is worth carefully examining the samples presented and their main characteristics. They must comply with all the necessary requirements.

There are several nuances, on the basis of which it is worth choosing materials.It is important to know that the means with a small thermal conductivity are suitable for this best. The material must be moisture resistant. it important criterion When choosing a heater for outdoor And with a rather worn roof.

Insulation and other materials are required to serve for quite a long time, so there must be durable. Don't forget about environmental safety. To work, you need to choose non-combustible or low-minded funds.

For a private house best insulation - This is a ceramzite.

Frequently use chips or sawdust, often use stone or mineral wool, eco-art, foam, penplex, aerated concrete. Polyurethan is a sprayed type of material.

For roof insulation in wooden house It is worth using certain types of insulation. Select the material must be strictly in accordance with the type of overlap. It happens two types - from concrete or tree. For concrete it is worth using insulation heat. They are in the form of a mat or stove. As a rule, they are a falling type.

Often builders use and insulation of natural origin. These include sawdust, hay, coniferous needles, last year's leaves, algae or reed. However, it is worth remembering that all natural materials except sawdust are subject to severe rotting.

It is important to approach the issue of the selection of the material is extremely responsible.

Which to choose?

The insulation in the form of chips or sawdust is considered the most ancient material. In areas where woodworking production is strongly developed, this material is very cheap. It is perfectly suitable when creating a layer of isolation from above wooden overlap. The essential minus of this type of insulation is its high flammability.

In the construction industry there are three types of mineral wool:stone, slag and glass. Stone wool is made from rocks with the addition of clay, limestone and formaldehyde.

The significant disadvantage of such a material is that in its composition it contains harmful substances. When heated, they turn into phenols and fall into the air. More securely believes balzat wool, in it harmful substances far less.

The slag wool is obtained as a result of the use of domain slags and other waste of the metallurgical industry. Due to the average thermal conductivity and ability to absorb a large volume of moisture, it is not suitable for cold ceiling insulation.

Glasswater is the most suitable material, besides, it has an extremely low cost.

An explicit minus is that when a piece of material on the skin or mucous membranes of a person, it can harm health. In this case, experts advise when working with this type of insulation to use gloves and special means protection.

The explicit advantage of the cotton as the insulation of the house is the simplicity of its transportation and installation. This is possible due to low weight. Wat has a small combustion and at high temperatures can only swing. For the owners of country houses and cottages it is important to know that glass gamble is not the most favorite material for the habitat of insects, various rodents and mold.

Polyeneetylene is a foamed PVC, which is applied by a foil layer. Manufacturer Releases this insulation In rolls width to one meter. You can warm the ceiling and with the help of foam. But it is important to know that in this case an additional installation of suspended structures will be required. In a private house, it is also good to use polystyrene foam. It fits tightly and at the expense of a good density is often used in the attic, as the basis for further putty.

Ceramzit has great popularity. Better if it is made of light alloy clay. Due to this, the material is an easy and rather porous structure. Production modern insulation Allows you to choose foam. Many builders are considered an avoard as insulation. This material on many characteristics is similar to mineral wool. But it is more elastic and stable to load.

Another worthy option is Penophol. His a distinctive feature is a property to reflect thermal radiation. This material is well suited in the role of the insulation inside and outside the house. This means it is quite possible to insulate the entire country house, and not just the ceiling.

Do not forget about polyurethane foam. It is a convenient and good material in quality, meets all the necessary characteristics as a heater. Represents a mounting foam that you only need to spray to get desired result. He not only insulates, but also contributes to the sound insulation of the room.

For the tenants of an apartment building, it is best to achieve permission from management company And insulate the sex of the attic.

An excellent option in this case will be the use of clay. This material is fireproof and perfectly protects against moisture.

Inside the apartment often applied vapor-permeable insulation.In the process of holding repair work The master uses special materials that fill the entire area of \u200b\u200bthe ceiling. After that, you can proceed to finishing work with the help of drywall.

Application area

As noted earlier, the materials can be used indoors, and above the ceiling. To eliminate the defects of wooden overlap perfectly silk and clay. The floor is worked with clay, then sprinkled with a thin layer of sand and sawdust is spread from above.

In order for the sawdusts, the mouse does not start, it is worth using carbide ahead with a haired lime. In the old house from the bar, the height of such insulation can reach thirty centimeters. When using the attic on economic purposes from above, such a insulation is enough to put wooden boards.

Experienced masters are used special film With waterproofing.

She skips pair particles from residential premises. For a residential building, you can use a mixture of clay with sawdust. Excellent option in a chopped or frame house.

On the concrete overlap of an apartment building in any case will go.This will happen in the process of repair work or preventive. In this case, it is worth choosing a dense foam or mineral wool. On the insulation, it is necessary to put a plywood or board.

These two types of insulation and less dense layer can be used. Due to this, the material will be released much cheaper. In this case, on the plate you need to make a tree crate. It is better if it is on the stands, because the altitude mounted can reach twenty or more centimeters. The insulation is stacked under such a crate and a clearance is made for ventilation.

For insulation reinforced concrete overlap In a brick house you can use foam. In this case, it is not about the release of poisonous substances during fire. Residential apartments are separated from it with a special overlap that does not burn.

In the presence of overlapping from a tree, the foam is undesirable.

This applies to the norms of fire safety. The most common view of the floors between the floors is a tree. In this case, your choice is to stop on the eco-button. This type of material is put in the mound, it can fill any space.

Eco-plates are placed in several layers. It is important that the seams of the layers are blocked. After insulation, the attic is already turning into an attic, but it concerns private houses and cottages.

Recently, the question of warming in the basement has become recently.

IN modern houses This room can be equipped with a real living room.It can be a cabinet, a gym or workshop. In any case, it is possible to use this room only if there is a comfortable temperature for a person in it. The insulation of the basement is the right step towards saving energy and heat throughout the house. Even if the basement is unsuitable for equipment in it useful space, it still needs to be inspired.

This can be done internal, external or combined way. The selection of heat heaters is quite wide. The main thing is to choose suitable option For specific purposes.

Technology of work

It is very important that the roof of the house was warm. It is expensive, but subsequently saves the budget. After all, electricity costs are significantly reduced.

When the ceiling insulation works, the weight of the material itself is of great importance. Due to the weight of the cerazyt, it cannot be used in the presence of floors of wood. Due to the severity of the material, the flooring can completely fail. Ceramzit should be applied if available concrete overlaps. The ceiling and roof insulation scheme can vary somewhat.

Preparing the attic begins with clearing the entire area from the rubble and garbage.

If there is an old insulation, then it is also better to remove it. It can create an excess load on overlap.

The next step should be thoroughly insulated. It is necessary that in the spring it is not necessary to remove the effects of flooding. This uses a special membrane. It is laid between the lag so that about four centimeters it is screwed into the Boca Lag.

The insulator must be pressed to lags very tight. It is usually fixed using a stapler or glue.

Wooden overlap There must be oxygen tolerance at least on both sides.

After that, laying of the first layer of the insulation begins. It is put to the level of lag. Then the insulation is covered with a membrane that has a small throughput oxygen. Then the flooring is stacked. Leave special gaps for ventilation.

It is necessary to competently pick up the thickness of the insulation.

It should be considered a layer of waterproofing. Often builders use a thickness of about fifty millimeters thick.

When conducting warming with polyurethane foam, you will need to call the wizard. The spraying process occurs under high pressure. Due to this, all the cracks are filling. The layer thickness ranges from ten to twelve centimeters.

Mineral wool as a heater has a different thickness. Indicators depend on the scope of work. The wool layer used as the insulation can be from two to twenty centimeters.

Polyenethylene is foamed polyethylene.

The thickness of such a material is from one millimeter to two centimeters. Polyfoam is placed by plates. The thickness of one plate varies from two to ten centimeters. This is obtained due to the fact that the material needs to be imposed on each other.

When insulation, attic is used various materials For insulation. But the average varies from fifteen to twenty centimeters. The layer of clay and straw is approximately ten centimeters. In order for everything to be exactly, it is worth using a special ruler or a stick.

Thermal insulation options

Cold ceiling and roof insulation options There are only two, or the ceiling indoors is insulated or insulated outside. Both of these options will greatly help maintain heat and electricity in the house. Each of these options has its own set. essential materials and installation technology.

Materials for thermal insulation are divided into two classes - these are vapor-permeable and steamproof.These readings indicate the ability to absorb moisture. It is for them that one or another type of material is chosen to perform work on the insulation of the ceiling or roof. For work on external insulation, a countertile material is used, and for internal work - vapor-permeable.

Inside use most often mineral insulation. Works can be done using rolled glass. Complete with plasterboard ceiling, hot air buffer will be obtained. The process of insulation is carried out at the time of installation of the suspended ceiling.

It will be right if the framework of the profiles will be made first, in which the insulation will be placed.

If the work is carried out with your own hands and on your own, do not forget about safety technique.

Glasswater is a rather dangerous material. Methods of fastening glass gambles to the ceiling are quite simple. The material is glued with glue for tiles. It is important that the glue drove as fast as possible. After the entire insulation is dry, it is sewn with plasterboard.

It is worth remembering that the cotton can not be traaming and pressing.

Due to such features, it is attached to glue, and not on the self-tapping screw. The whole thermal effect of mineral wool lies in the abundant amount of interlayers that are placed inside the wool.

The ceiling insulation in a private house is a procedure that the owners are often neglecting, focusing on the walls. And in vain - a lot of heat is consumed through the roof. After all, warm air is easier, and therefore rises up. If the ceiling is not insulated, then heat does not meet barriers and freely comes out. Understanding how to warm the ceiling correctly, it is possible to significantly reduce heat losses - the house does not have to heat up for a long time using expensive energy.

Methods

The ceiling insulation in a private house can be carried out in three ways. The first option is the ceiling insulation from the inside of the room. It is possible if the features of the building architecture do not allow the external (attic) heat insulation.

Consequently, the second method is the insulation of the ceiling in the attic, outside. This is the most popular way of thermal insulation, which is not only easier and faster, but also the cheapest. The third method is combined, which provides insulation, both outdoor and internal. Basically, it is used for large heat lines of the room.

Materials

For thermal insulation ceiling, the following materials will be required:

• insulating material (mineral wool and foam);
• material for waterproofing (pergar);
• edged board, nails and wooden rails;
• mounting foam for sealing.

To cut off the rails desired sizeIt will take hacksaw and electric jigsaw. Foam plates can be chopped with a knife.

The insulation of the ceiling from the inside with their own hands can be carried out with tiled mineral and polymer incomplete materials, which include polystyrene foam, foam, mineral wool. For external heat insulation, clamzit, sawdust, insulation of bulk components based on polymer mixtures are suitable.

Working with the roof

Before heating the ceiling in a private house, the roof thermal insulation should be carried out. Most of the residential buildings are equipped with a double roof and insulating them from the inside after the completion of construction. One of the insulation options:

• it is covered with the roof of the roof of the waterproofing layer;
• mounted wooden doom for installing insulation;
• plates of the insulation between the crates of the crates are stacked;
• all gaps and cracks are stirred by mounting foam;
• the boards are nailed, which will fix the plates of the insulation.

It is important that a space for ventilation remains between the waterproofing film and the insulation, the air will pick up water vapor, and carry it out of the room. If there is no ventilation, the humidity will increase and condensate will appear.

Mineral wool

In private houses, the ceiling is insulated by the attic. It makes it easier to install with your own hands and does not reduce the space of the residential premises. Consider how to insulate the ceiling of the Ministry of Service. First of all, it is necessary to prepare the area of \u200b\u200bthe attic overlap for insulation according to the following scheme:

• paul attic covers with a steampossed film;
• wooden rails are attached at such a distance so that Mineral Wool blocks can fit between them;
• if the heat loss is significant, the insulation is placed in several layers;
• the last layer of the insulation must cover beams, otherwise the tree can become a "cold bridge;
• the remaining voids are filled with slices of foam or bleed by construction foam;
• the second layer of the film for vaporizolation is mounted.

Increased attention to moisture insulation is due to the fact that minvat, falling into a wet environment, loses heat insulating characteristics.

Film for moisture insulation is better spread with a margin. The edges of the film using a stapler are attached to walls or side beams. After insulation, in the attic you can arrange residential or utility rooms.

If a frequent use of the attic space is planned, then the floor of the boards should be used on top of the heat insulation. If the attic will not be used, it is enough to nail a few boards to move around them, like along the tracks.

Ceramzit

If mineral wool does not like the insulation, you can insulate the ceiling with a clay. Ceramzite has many advantages:

• it does not damage rodents;
• ceramzite - bulk insulation, so they can fill any space;
• thermal insulation using clay will serve for a long time

But it must be remembered that the ceramisite has a relatively small thermal insulation characteristics, so the insulation may need a lot. This will increase the pressure on the overlap of the house. As a conclusion: clamzite is used to insulate the ceiling in case of insignificant heat loss when you can do with a small number of this material. Ceramzite does not respond to a wet environment, so it does not need to be protected by waterproofing materials.

Work with foam

Polyfoam is a very popular insulation. It is released in the form of plates. For insulation of premises, you can purchase a bulk foam. Deciding on the choice of insulation, many stop on the foam. And not in vain - it has very advantageous characteristics:

• polyfoam - lightweight material, so pressure on bearing structures will be minimal;
• installation of plates can be performed independently;
• polyfoam plates can always be cut with a knife so that they are fed inside the crate;
• modern foam is not afraid of fire and has a low cost.

Stages of mounting

The insulation of the ceiling by foam consists of the following procedures:

• the ceiling overlap is covered with waterproofing (pergamine) - pergamine is cut into the strip so that the material fits between the beams;
• from the side of the beams, it is left for 5 cm of material, and then parchment is attached wooden rails to the ends of the beams;
• the plates of foam are cut with a knife so that they are placed between the ceiling beams;
• all the cracks blew by mounting foam;
• the second layer of pergamine is laid over the design.

The amount of insulation is calculated, based on the heat loss of the building. Sometimes the foam layer has to lay several layers of mineral wool. The insulation design is mounted so that the upper edges of the ceiling beams close the insulation.

Even with the insulation of the ceiling with their own hands, it is worth seeking a consultation to a specialist to know for sure the required amount of material and choose the correct insulation.

If you compare with urban apartments in high-rise buildings, private houses have large square Contact S. external environmentTherefore, the question of high-quality thermal insulation here is much more relevant. About 35% of heat goes into the surrounding air through a dishepsed ceiling if the roofing and attic room is not insulated with a thermal barrier. Losing so much heat is wasted - non-disabilities, so we will consider optimal options Thermal insulation ceiling floors.

Warming from the inside or on the side of the attic - what is preferable?

Modern building technologies provide for the device heat insulating layers Simultaneously with the construction of the construction. In this case, the most convenient and effective installation schemes of the insulation are also selected at the design stage, taking into account the type of overlap, the total load on building structures, the need for heat saving in this climatic belt. This happens ideally, if it is erected new house With compliance with the construction requirements and rules.

If a private building was built a long time ago, or recently, but on its own, it is quite aware of the option that high-quality thermal insulation, including ceiling floors, may not be in the house. In such a situation, homeowners have to independently solve the problem of insulation, selecting the methods that meet the needs for heat saving, the peculiarities of the construction in general and the type of overlaps in particular. The first question that arises on the way to solve the designated problem is the side of ceiling floors with which it is more convenient and more expedient to arrange a thermal insulation barrier.

You can warm overlaps from each side, and in any case it will be correct. But when choosing a method of insulation, some nuances should be taken into account. The first one is the height of the ceiling floors. If the ceilings are low, and then there is no useful space of desire, it is unambiguously asked for insulation on the side of the attic, because the layer of insulation (at least 5-6 cm) plus the finish (2-3 cm) will make the ceilings even lower. Another situation - the rooms have already made the finish, the interior is decorated, and it is quite satisfied with households. The ceiling insulation will be needed to make repairs again, which is inappropriate in all respects. Here, also in preference, laying the heat-insulating barrier on top of overlappings.

Insulation the ceilings from the inside makes sense only in a situation where the house is held overhaul. In this case, the embodiment of one of the methods of internal thermal insulation of ceiling floors, which is carried out during the repair finishing work. Although recently homeowners are increasingly preferred to warm the ceiling on the side of the attic. So much more convenient, less expensive and, moreover, is easy. And this is a strong factor if the device of the heat-insulating barrier is assumed with his own hands.

There is a variant of the insulation of overlaps on both sides. So make those who want to turn housing into an impregnable fortress for winter jellows and summer heatIn order to continue to save money for energy resources.

We are looking for a suitable material - polymers or fiber?

Now there is a sufficient choice that you can apply for our purposes. Along with the use of modern thermal insulation materials, traditional insulation often apply, which serve for this not one century. These include wood chips and sawdust, as well as materials based on them (opilk concrete, a mixture of woodworking waste with clay). Some fall asleep sex as a layer of dry leaves or legs coniferous trees. Such ways of insulation of overlaps used our great-grandparents, but nothing prevents the use of such absolutely natural and often free materials in our time. Although modern technologies and materials in consumers in preference, therefore, briefly consider their diversity and main characteristics.

Classifying materials applicable to the insulation of ceiling floors can be disselected to several groups:

• polymer thermal insulators;
• fibrous insulation;
• sprayed materials;
• bulk substances.

Polymers include the well-known foam and rapidly gaining popularity extruded polystyrene, known to many under the commercial name "Penoplex". Polyfoam applies very widely for thermal insulation purposes in construction. Popularity The material provides two factors - very affordable cost and good thermal insulation properties. High-quality material with a density of at least 35 kg / m 3 also has sufficient hydrophobicity, so that the need for a device of hydro and vapor barriers during the installation of the insulation layer has disappeared. All would be good, but there is a main one of which is a flammable accompanied by extreme toxicity. The smoke allocated during the burning of this polymer is able to send anyone to the forefers, who will breathe it 2-3 times. For this reason, in many developed countries, this insulation is prohibited for heat-insulating work In residential buildings.

Penoplex is deprived of many of the disadvantages of foam. It refers to the class of materials that do not support combustion or self-fighting, so its use in residential construction is not limited. In addition, polystyrene is absolutely not susceptible to the effects of moisture, is not affected by the bacterial and fungal microflora. Polystrax strength is one of the highest, if compared with other heat insulators, so polystyrene is often used where the strength characteristics play an important role (under the tie, thermal insulation of building grounds, basement). According to the thermal insulation properties, the polystyrene is approximately the same as the foam - to create a reliable thermal barrier, a sufficient layer of insulation is 5-10 cm (depending on the geography of the region).

Fibrous materials for thermal insulation works in construction include varieties of mineral wool. The material varies in the nature of the raw material, which is applied to the manufacture of material. All types of minvati are produced by melting minerals and forming fibers fastening with organic adhesive. If the fibers are formed from molten glass, the fiber optic is obtained. Shelotte is made in the same way of domain slags and other mineral waste of metallurgical production. Basalt wool considered the most qualitative material From this category, it is formed with thermal impact on some types of rocks.

All fibrous insulation are made of different densities. The tallest specific gravity They have mats used primarily for facade heat insulation under shuttering. Such thermal insulator is durable and hard, therefore forms a solid surface for conducting finishing works. The midwate of the average density is also made in the form of mats, but the material is more loose and does not differ in high strength. Mineral wool with the lowest specific weighing on sale enters the rolled rolled. For the insulation of the ceiling in the house, you can apply an average and low density minor and low density, and the first will be more appropriate in thermal insulation on the side of the attic room with a cold roof, the second is for the thermal barrier device from the inside.

Sprayed and bulk options - there is from what to choose

The last word in the technology of insulation of construction surfaces is sprayed heat insulators. These include polyurethane foam foam and eco. The first material is a polymer, the second is made from natural raw materials (cellulose). Both heat-insulators are applied to insulated surfaces by spraying, although in some cases the eco-water is falling asleep in the existing gaps in a dry form with the subsequent tamper.

Polyurethane foam in chemical nature, the method of applying and the structure of finished thermal insulation is very close to the usual mounting foam. To prepare a foamed material having excellent adhesive properties, two components are used, which are dismounted and then applied using special equipment. The advantage of a sprayed insulation is in its seven, which warns the formation of cold bridges. Polyurethane foam in a polymerized (frozen) state is not a fuel and has 1.3 times the best thermal insulation characteristics than foam. The lack of thermal insulator - in gradual destruction under the influence of ultraviolet (need to be protected) and the impossibility of working with it with it (equipment is expensive and purchased it for one-time use).

The most applied bulk thermal insulator is clayzit - porous granules of various fractions. The raw material for the production of clay is the usual clay, so this insulation refers to environmentally friendly and natural. This insulation does not burn, has moderate hygroscopicity and good thermal insulation properties. The ability to resist heat loss depends on the magnitude of the granules - the less fraction, the higher the thermal conductivity.

For insulation of the attic floor, it is advisable to use a clamzite of the fraction 5-10 mm.

Thermal insulation ceiling by residential rooms

Heat overlap from the inside can be in two ways. The first provides installation heat insulating plates Or mats directly on the surface of the overlap with glue and additional fixation with special dowels. This method is better to use if a reinforced concrete plate is used as the overlap. The second technology provides for the device of the crate under the subsequent sheathing sheets of plasterboard sheets, plastic panels or clapboard. In this case, the insulation is laid between the carrier elements of the frame. This method will be carried out with any type of ceiling floors. Both methods give a good thermal insulation effect, although the thickness of the layer is often limited, due to the desire to maintain the maximum of the useful space.

An extruded polystyrene is often used to implement the insulation of the insulation on the slabs, although mineral wool mats with high specific weight can be used. Preference is given to polystyrene for several reasons:

• the material is easier, more convenient in operation when installing it;
• the thermal conductivity of the polystyrene of the same thickness is approximately one and a half times lower than the same indicator of high density minvats;
• to form a finishing layer on the surface of mineral wool, you need to have skills of such activities, while plastering the polystyrene is not more complicated than on plasterboard.

In general, the installation of these insulation differs little. The difference is only used by polymer cement mixtures for gluing thermal insulation sheets. The sequence of actions with this method of insulation is as follows:

• plate of overlapping processing the grinding mixture;
• we are preparing polymer cement glue (according to the instructions on the package);
• the adhesive mixture is applied to a sheet of insulation (around the perimeter and in the center), after which the polystyrene slab is pressed to the concrete surface and exhibit in a horizontal plane;
• after setting the glue (approximately after a day), the insulation sheets additionally fix "umbrellas" - special dowels with a wide circular hat.

It remains to plaster the insulation using the reinforcing mesh and apply finishing layers. If the second method applies to lay the insulation to the intervals between the rails or profiles, the mining or low density minor or low density. The thermal insulation is placed between the elements of the frame and slightly fixed by the rented straightfight of the direct suspensions, which the profiles are attached to the overlap, after which the lamp closes with the trim.

Device of the heat barrier by half the attic - available methods

For the device of the thermal barrier on the side of the attic room, all of the materials mentioned above are applicable. If it is necessary to hire specialized brigades for insulating eco-art or polyurethane foam, to form heat-insulating layers with claying, mineral wool or polymer sheet insulation Will not be difficult to any home master.

If the overlap is executed reinforced concrete slabMore expedient to apply clamzit, falling asleep with a layer of up to 15 cm, or to lay a penplex, filing the seams between the sheets of the polymer insulation by mounting foam. With it is better to use Minvatu, because by the ability to skip water vapor it is similar to wood. Laying the fibrous insulation is carried out in the intervals between carriers wooden beams, after which the parobarar is arranged from the corresponding film. Then the beams are surrounded by counterbours, which will be the basis for the flooring board of the attic floor.

If there are free access to sawn waste, you can maximally reduce the event, filing the space between the beams with a mixture of small chips and sawdust. This method of thermal insulation will be the most environmentally friendly and natural for overlapped made of wood materials.

In the fact that in private houses with a "cold" roof it is necessary to warm the ceiling on the last floor, you do not need to persuade developers. The question is different: how to make it properly, not overpaying the extra money for the materials. Find out the answer to you will help the step-by-step leadership set forth in this article. Here we will explain how to insulate the overlap by the attic (or room) and what to take action so that there is no condensate.

The better to insulate the attic floors

The range of materials for ceiling thermal insulation is so wide that the ordinary homeowner is not easy to make a choice. Judge for yourself:

• mineral wool based on fiberglass and basalt fiber;
• polymer insulation - foam, extrusion polystyrene foam and foamed polyurethane;
• bulk construction materials - vermiculitis, ceramzit;
• folk remedies - sawdust, straw or reed (can be applied in a hand with clay);
• relatively new cellulose-based insulator - Equata.

This is the applying of Eco

Comparing insulation, it is impossible to say that one is bad, and the other is good. They differ greatly by properties, price and scope of application. An important role is played by the budget allocated by the developer on the thermal insulation of the ceilings of a private house or cottage. Therefore, it is worth considering each group of materials separately.

Mineral wool products

These porous building materials are produced in the form of plates and rolls, the density varies in the range of 35-150 kg / m3. We list them features:

1. Basalt minvat is absolutely not lit and calmly maintains temperatures up to 600 ° C, and with further heating it is destroyed without ignition. The heat resistance limit is 200 ° C, so it is considered a difficult-scale substance.
2. Both isolators are well passed by water vapors and are able to absorb moisture, resulting in thermal insulation properties.
3. At the cost of Vata occupies an average position between a cheap foam and more expensive expanded polystyrene.
4. The thermal conductivity of mineral wool products depends on their density. The averaged value is 0.045 W / m ° C, it is a rather high indicator.
5. Tight plates are extremely rarely eating rodents.

Plates of basalt wool

Reference. The standards of most countries are prohibited for the use of indoors, since it is unsafe for health inhabitants of residential buildings. Self famous manufacturers - URSA brands (Ursa) and Izover (Erult).

The main scope of the application of both types of Minvati is wooden and frame houses. Unlike polymer insulating materials, it allows wood to "breathe" and do not rot from humidity, because it has high vapor permeability. At the same time, fibrous insulation requires protection from direct moisture from the street.

Fiberglass plates and rolls are allowed to apply for ceiling insulation outside, from the cold attic. Stone Wat You can use from the inside of buildings, but at the same time it is sealed with a vapor barrier film.

Warm polymers

By properties, this group of insulation is the complete opposite of the Minvat. Polyfoam and extruded polystyrene foam, well known under the name Penopleplex (brand name), is able to ignite and burn, no matter what the manufacturers argue. And only polyurethane applied mechanized method In the form of foam, it can be withstanding fire no longer than 30 minutes, but after being destroyed. At the same time, materials practically do not miss steam and do not lose properties during wetting.

So there is a spraying of polyurethane foam

Note. The foam is still permeable for moisture, although it passes it in smaller quantities than cotton.

Thermal insulation characteristics of polymers are the best among all insulation:

• polyfoam - 0.04 W / m ° C;
• exterzional polystyrene foam - 0.035 W / m ° C;
• polyurethan - 0.03 W / m ° C.

Heaters are bad "friends" with wood, which often leads to its rotting at the point of contact. Therefore, in wooden dwellings and pairs of baths with high humidity, their use is allowed together with the active supply and exhaust ventilation device. The best materials are combined with concrete ceilings and cellars overlap.

Polyfoam is the lowest, but inferior in durability, in addition it loves to nibble mice. Foam polyurethane is also inexpensive, but requires costs to apply with specialized equipment. Polystyoltilol occupies an average position in terms of cost, and according to practicality - the first. It is durable and durable, besides easily mounted on the ceilings with his own hands, including inside the premises.

Here it is clear that the Penoplex is simply fastened with self-draws

Other insulation

We combined these building materials into a general group on one basis - a bulk structure. The indicators of their thermal conductivity are reflected in the table:

Funny insulation are popular thanks to the cheapness (except vermiculite) and ease of use. But it is necessary to understand that in moderate latitudes the calculated layer of the same clay should be at least 40 cm, otherwise thermal insulation will be mediocre. To load the ceiling is not always possible.

Straw on thermal conductivity is not inferior to foam, but in a dry form it is stored only a few years. To extend the service life, it is customary to mix with clay, but then the insulating properties are reduced, as can be seen from the table. The compromise option is small sawdust, fastened with a thick layer.

Reference. All organic insulation are very loved by rodents. They appear at the beginning of the cold period and arrange nests for the winter in a layer of sawdust or the Saman.

It turns out that these budget materials can be used for heat insulation overlap, but with reservations. Vermikulite roads, and fall asleep clamzit makes sense only in the southern regions. To use sawdust, you need to take measures to combat rodents, for example, to put ultrasound dischargers.

Determination of the thickness of thermal insulation

When we figured out how to insulate the ceiling, it is necessary to find out the thickness of the insulating layer. Ideally, such calculations must perform engineers designers using a rather complicated technique. It takes into account the thermal conductivity of all materials of the design, down to the plasterboard cladding.

We offer a simpler method that allows you to determine the thickness of the insulation in a simple formula with an acceptable accuracy. An algorithm of actions such:

1. Learn the accurate thermal conductivity indicator λ (W / M ° C) of the selected material or take the value indicated below in the table.
2. In the regulatory building documentation of your country of residence, find out the minimum allowable heat transfer resistance R (m² ° C / W) for overlap in a particular region.
3. Calculate the thickness of the insulation in meters by the formula Δ \u003d R x λ.

Example. According to SNiP, the insulation of overlaps in Moscow should provide heat transfer resistance R \u003d 4.15 m² ° C / W. If a foam plate with a thermal conductivity λ \u003d 0.04 W / m can be placed on the ceiling, the thickness Δ \u003d 4.15 x 0.04 \u003d 0.166 m or rounded 170 mm will be required. The thinnest layer will come out of polyurethane foam - 125 mm, and the most thick - from the ceramzite (415 mm).

How to make insulation on the side of the attic

The external thermal insulation of building structures is considered correct because it eliminates the fight against condensate that can be formed at the junction ceiling material With insulation. When the latter is located on the cold side, the water vapor from the residential premises cannot get into its thickness and condense, causing the appearance of mold.

To block the path of a couple on the attic, the first layer in the "Pie" goes the usual dense film, as shown in the diagram. Thermal insulation is stacked on top of it, and the lamp is bought from below interior decoration Ceiling. Above the insulation need to do ventilation clearance (Product), and then hide the waterproofing membrane, passing moisture only in one direction - outward.

Note. The gap between the insulation layer and the membrane is necessary for the conclusion of condensate generated due to the dew point. Without production, moisture is accumulated in the insulation, reducing its ability to resist cold. For this, natural ventilation is organized under the roof.

Ceiling insulation on the attic of the pitched roof is performed according to this technology:

1. The vapor barrier film is attached to the beams of overlapping from the bottom in brackets or using slats of the crate. If the ceilings are already lined and lined, then place the film on the floor of the attic, bypassing the board, as shown above in the photo.
2. Squeeze a row of slab or roll insulation between beams. If the step has not coincides with the width of the insulation, cut the last clearly in size between the boards.
3. When you need to do 2 or 3 layers, plates put the rotor (with overlapping the lower joints) and the beams themselves. Soft rolled material Do not tram and not signate, it must be completely straightened.
4. If the level of thermal insulation turned out to be below the roofing boards, then the ventilation product, count, is ready. It remains to cover the entire area of \u200b\u200bthe diffusion membrane, to pin the bars of the counterbalax and the boardwalk.
5. Reverse situation: insulation above the level of beams. Then they need to build up wooden barsBy fastening the latter across the boards.

The device of a claying or sawing insulation layer is also made using vapor barrier films. The material falls asleep between the beams at the estimated height, recalls and overlaps the membrane. Washing sawdust is not necessary, so as not to worsen their thermal insulation properties.

Concrete coating under the scope roof is insulated by the same technology. More The process of thermal insulation is demonstrated on the video:

Cleaning from within the premises

Not always there technical opportunity Alone to perform outer thermal insulation of coatings. There are many examples: Apartments of the last floors, loggias with balconies, attic of private houses. In these cases, nothing remains except to insulate the ceiling from the inside. So boldly proceed to prepare - close all the slots of the mounting foam, wood process with an antiseptic, and concrete - appropriate primer.

There are 2 ways internal insulation Coatings:

1. Installation of slab material - polystyrene or basalt wool - on glue with subsequent fixation of dowels, if it comes to a concrete surface.
2. The device of suspended ceilings with a cladding isolation laying.

In the first variant mineral wool or polystyrene plates Mixed to the ceiling on the adhesive mixture or mounting foam so that the joints of the neighboring rows do not coincide. After soaring glue, each element is additionally fixed by dowels in the form of fungi, as done in the photo. From the bottom the insulation is closed with steam insulation, after which the finish coating is mounted - plaster or stretch ceiling.

In the second case, metallic is attached to the overlap wooden frame With a row step, equal to the width of isolation (usually 600 mm). The lower plane of the frame must be defending the ceiling on the thickness of the insulation or be lower. Then the roll of Minvat is taken and inserted between the rims of the versius with additional fixation of the dowels, the plates of polystyrene foam are sitting on glue. Further - vaporizolation and finishing finish.

Conclusion

Performing independent insulation Ceilings, it is important not to confuse paro and waterproofing films, but put a superdiffusion membrane correctly - a labeled side up. This is the only difficult moment in the entire procedure, the rest of the work is quite simple. Last nuance: After unpacking the Roll of Minvati, let it straighten it and do not compress it anymore: this is a working condition of the material.
