The better to insulate the ceiling in the apartment. How to insulate a wall inside an apartment: the better to insulate a wall inside an apartment on your own. Materials to be purchased

Many are concerned about the question: "How and with what to insulate the ceiling in a residential area?". And not just to insulate, but to make sure that the insulation is "in combination" and a decorative material - and there are many such options. Our article will discuss how to choose the best option for thermal insulation material, and how to properly insulate the ceiling in a particular room.

Ceiling in the apartment

Insulation of ceilings in an apartment may be needed only in one case - if it is located on the top floor. And it doesn’t even make much difference whether there is an attic in the house or not. Even if there is, it still does not heat up. Unless, in this case, the likelihood of your ceiling getting wet is reduced if the roof is leaking.

But it also happens that after a good downpour or melting snow, the ceiling in your apartment is wet. And where there is dampness, there it is cold - and such a nuisance, alas, is not uncommon, especially in old houses.

And if this still happened, you should not despair. Simply, before you insulate the ceiling in the apartment, you need to perform a series of manipulations. Of course, you need to get rid of it first, and our site has detailed articles on this topic. But if it didn’t come to that, then the main thing that needs to be done is to block moisture.
To do this, you will need a waterproofing repair compound such as Aquastop, Kalmastop, Gidroizol. These are penetrating soils that can not only block incoming moisture, but also displace existing moisture from the thickness of the concrete.

These compositions are effective even in cases where there are cracks in the plates (see), open up to three millimeters. At the same time, the treated structure does not have to be dry. If there is a seam on the ceiling formed by the joint of the plates, and it is large enough, you will need a seam composition, which, when crystallized, forms an insurmountable barrier for water.

Advice! After processing the seams and corner joints of the ceiling, they can be reinforced by gluing self-adhesive fiberglass insulating tape around their perimeter.

After finishing the processing of the joints, you can begin to apply waterproofing primer over the entire area of \u200b\u200bthe ceiling. We insulate the ceiling after the coating layer dries. If you made waterproofing using the technology that we described above, now your ceiling is not afraid of anything.

You can decorate it in any way convenient for you. But you still need to mount the insulation, and this requires a frame. If the height of the room is quite low, and you don’t want to take away 12-15 cm from it, you should consider options for frameless insulation.

Heat-insulating plaster

And here is the first idea for you, how to insulate the ceiling on the top floor. One of the frameless options for insulation, not only the ceiling, but also the walls, is warm plaster.

What is it:

These are dry mixes composed of porous fillers and plasticizing additives. Astringent-based mixtures used for internal works, is all the same gypsum.
Different kinds heat-insulating plasters differ from each other only in the type of filler. Depending on the manufacturer, the filler can be: granulated expanded clay, expanded polystyrene, foamed glass or silicon, vermiculite or perlite expanded sand.
In cheaper options, sawdust is used, but for an apartment this is not the most the best option. We will not expand on the properties of each type of warm plaster. Let's just say that they all have good adhesion to various surfaces, resistant to moisture and mold, and have a low coefficient of thermal conductivity.

For residential premises, it is best to use plasters with fillers. natural origin. They are applied to the wall without prior alignment, in one layer. It does not require the installation of a reinforcing mesh. Some of the thermal insulation plasters do not even require finishing.
For example: mixtures of foam glass. They are so plastic that they even allow you to make a relief on the surface of the ceiling or wall, or to form decorative elements that look like stucco molding. Such plaster itself, due to the coarse-grained filler, creates a coating with an interesting texture.
Naturally, this material is the most expensive compared to others. warm compositions. On the other hand, the coefficient of thermal conductivity of plaster based on foam glass is 30-40% lower compared to that of mineral wool.

By the way, it can also participate in foam glass. There are aluminum acoustic panels with foam glass coating.

They are very light, rigid, have excellent sound insulation. The panels have various formats, and can be used not only for suspended ceilings, but also for wall cladding.

Cork agglomerate

How and how to insulate the ceiling in order to do without leveling and mounting the frame, and even better - without finishing? We offer another, environmentally friendly option for ceiling insulation.

This is the lining of its surface with cork agglomerate. The cork is absolutely not afraid of moisture, it is very light, it can be mounted both on glue and on the crate. The installation method will depend on which coating you prefer: rolled, or in the form of plates.
This material is made from the bark of a certain type of oak called cork. White agglomerate is used as decorative coatings for walls and ceilings.
It is obtained by molding and pressing granules in an organic binder: gelatin, coal-stone pitch, resins. Polymers are not used in the production of cork coatings.

A huge advantage of this material is its varied texture and colors, the possibility of staining, drawing, or stencil images. The cork coating perfectly hides small irregularities and defects in the ceiling, therefore it does not require preliminary leveling of the surface.
The only condition for sticking a cork coating is a cement base. That is, if earlier on the ceiling was plaster screed, it will have to be removed. From figures and elements cut out of cork different color, you can create applications, panels, and whole paintings on the ceiling.
We are talking about the ceiling, because it is he who is the topic of our conversation. Naturally, everything we talk about is also relevant for other surfaces. For finishing the floor and walls, cork coatings are used even more often.
By the way, flooring made of cork, intended for mounting on glue, can also be used for the ceiling. It is glued either to the base ceiling or to the surface of the slab insulation, as shown in the photo below.

And if you need to finish and insulate the whole apartment - why is the ceiling worse than the floor or walls? Often, cork is used in the design of the entire room.

Cork is hypoallergenic, so cork flooring is ideal for children's rooms and bedrooms. Such a room will not only be warm, but also perfectly isolated from noise. Why don't you decorate your apartment the same way?

Needless to say, all materials mounted on the frame are good when it is necessary to insulate the ceiling. And this is not only cork or solid wood, but also any sheet and modular options: drywall, MDF panels, even plastic - because insulation can be laid inside the structure.

Eco panels and foam tiles

How can you insulate the ceiling in order to create a design worthy of decorating the interior of the living room? Continuing the theme of decorative materials, which are an excellent insulation, one cannot but say about eco-panels. This is a relatively new material that has a three-dimensional surface, for which it received the status of 3D.

The three-dimensional surface of volumetric panels is perceived differently, depending on the lighting. Using an eco-panel for facing the ceiling, you can insulate the ceiling and get chic design. Just look at this diversity! Here are shown both options that already have a finish, and those that can be painted.
Eco-panels are produced from natural raw materials of plant origin: loose cellulose, chopped bamboo, reed, straw, or the same cork. The binder is organic resins. Due to this, this material is referred to with the prefix "eco".
These panels are mounted on glue - everything is very simple. In order for the ceilings in all rooms not to look the same, you can use panels with different textures, or you can use your own version of insulation in each room.

It is also possible to use small-format, glue-mounted and polystyrene foam or fiberglass tiles to get a beautiful and insulated ceiling. The latter, however, is more often installed on the frame, according to the system cassette ceilings. But, in such a design, additional insulation can be laid.

We insulate the ceiling in a private house

Speaking about the insulation of the ceiling in a private house, it should be noted that it may be needed in two cases. The first - if the house has a basement, or ground floor. The second is the attic ceiling, or attic floor.

If area basement corresponds to the total area of \u200b\u200bthe house, it is more convenient to insulate from the side of the upper premises - that is, in the process of installing the floor of the first floor. Unless, of course, the design of the floor allows.

If the floor is concrete

It is carried out simultaneously with their installation. All the nuances of this technology are detailed in one of the articles on our website.

We will consider the option when in a brick or block house reinforced concrete floor slabs were used. So, a flat and smooth surface of the slab is an ideal basis for tiling, laying parquet, or laminate.

In this case, it is unlikely that anyone would think of making insulation from this side. Therefore, it is better if the insulation is laid on the ceiling during the finishing of the basement.

First, the ceiling over the entire area is processed waterproofing impregnation- it will not allow condensation to collect. Then, depending on the choice decorative coating, an aluminum frame or a wooden crate is mounted.

As a heater, you can use plate materials: foam, different kinds mineral wool, expanded polystyrene foam. Roll insulation, in this case, are not very convenient to use.
There is practically no need to cut the plates. The main thing is to choose their size so that the width matches the profile pitch, or is one or two centimeters wider. Then the insulation will sit tightly in the cells, and will not fall out during the installation process. As a fixative for insulation, facade dowels with a wide cap are used.
Fastening the insulation to the ceiling, you can perform and adhesive method. Then, as a waterproofing layer, not roll material, and the absorbent primer of deep penetration.
After allowing the ceiling to dry after applying the impregnating waterproofing, they mount the frame and, having applied glue to the desired area, press the insulation plate against it. To perform this process, there is a special type of glue.

When the installation of the insulation is completed, a plastic film or foil is glued on top of it. This is a vapor barrier. If you buy a more expensive and modern insulation, front side which already comes with foil lining from the factory, you will only have to lay the plates with foil inside the room.

Here, in fact, the process of insulating the ceiling is completed. Next, mounted on the frame decorative surface: panels made of plastic or MDF, drywall, lining, etc.

If the insulation boards are mounted without a frame, then a fine-mesh fiberglass mesh is fixed on top of them, and plaster is applied. Most often, the very warm plasters that were mentioned at the beginning of the article are used for insulation. But this is on the facade. And in the case of the ceiling, you can use at least liquid wallpaper, at least decorative putty.

Ceiling in the basement and attic floors

To insulate the basement, it is quite possible to use another method: covering the surface of the ceiling, and indeed the entire room, with liquid polyurethane foam. But for this you will have to turn to specialists, because you will need special equipment, which does not make sense to buy to perform one-time work.

However, if the basement is residential, you can apply the same types of insulation that were mentioned above. In such cases, suspended ceilings are most often installed, since it is in them that lighting and ventilation.

When the house has two or three floors, it will be necessary to insulate the ceiling only on the last one. If there is an attic on top of it, the easiest way is to insulate the floor from the side of this room. There you can use all types of insulation, even polymer.
The most convenient, and even cheaper, will be the use of bulk insulation: expanded clay, vermiculite, expanded polystyrene granules or penofol. Ordinary sawdust is also often used for this purpose, although it must be remembered that sawdust is highly flammable, as, indeed, foam.

To fill the insulation, on the floor surface, previously covered with roofing material, they mount wooden logs. Logs must be pre-treated with an antiseptic. Loose insulation, especially if a combustible option is used, it is better to fill it with liquid cement mortar.
Expanded clay or vermiculite can not be poured. But, if the floor is done in the attic, which will be used as residential attic, these types of insulation are not only filled with a solution, a reinforcing steel mesh is also embedded in it.

After the concrete has set, a self-leveling floor is made on the floor surface. It turns out a solid and even base on which you can lay any floor covering.

Conclusion

Another scenario is also possible. In a house that does not have an attic, the roof slopes serve as the ceiling. This, in fact, also applies to the attic ceiling. Then the insulation is installed between the rafters. You may not need to make a crate - it all depends on the design of the roof.

The technology for the production of work here may not differ from that used to insulate the basement ceiling. When internal surfaces walls and roof slopes are so well insulated that there is no need to insulate and overlap. Especially if attic floor Heated like every other room in the house.

We hope that we have helped you figure out how to insulate the ceiling. For clarity, we suggest watching the video in this article.

Ceiling insulation is a mandatory stage of work in the construction of a private house with an unheated attic. But the ceiling surface of the apartment, located on the top floor, also needs thermal insulation. Moreover, the insulation of the ceiling can be performed in two ways. The choice of one or another option depends on the height of the room, the design of the house and the insulation used. Before you properly insulate the ceiling in the apartment, you need to study the characteristics, pros and cons of all heat insulators suitable for this.

When choosing a reliable insulation, pay attention to the following characteristics:

Take into account the weight of the material. It is important that the insulation does not heavily load the floors.
Use only harmless, environmentally friendly materials that do not contain toxic substances and do not emit them in the form of fumes.
The heat insulator must have chemical and biological resistance. It should not be damaged by insects and microorganisms. Biological stability is important when operating in conditions of high humidity.
For thermal insulation of the ceiling in the bathroom and in the kitchen, materials with low water absorption are used.
Fire resistance is an equally important requirement. Insulation should not drip, support combustion and smoke in case of fire.
If you do all the work yourself, consider the ease of processing and laying thermal insulation.
Give preference to insulators with good vapor permeability. They do not interfere with the air exchange of floor structures. Thanks to this, on ceiling surface condensate will not collect, which spoils the finish and building structures.

Warming methods

Since the ceiling insulation in the apartment is carried out only on the top floor of high-rise buildings, internal or outdoor installation heat insulator. Warming concrete ceiling the outside copes with the tasks of keeping warm much more efficiently, because this way concrete structures better frost protection.

Insulation of a concrete ceiling from the inside has significant disadvantages:

after fixing the insulation on the ceiling surface, the height of the room is significantly reduced;
when fixing the insulation from the inside, the concrete floor freezes heavily, which leads to significant heat loss in the room.

The external installation of thermal insulation, although it has many advantages, is not suitable for all apartments, but only for those above which there is a technical floor. Otherwise, you will have to use insulation from the inside.

Material selection

In my own way physical condition all heat-insulating materials are divided into fibrous, solid, loose and sprayed. The latter are practically not used for thermal insulation of apartments, because they require the use of special equipment for spraying, work skills and are expensive.

For internal thermal insulation the ceiling surface in the apartment uses polystyrene foam and extruded polystyrene foam, mineral wool and its stone variety. During installation, frameless or frame technology is used. The choice of mounting method depends on the density of the material. Dense insulators are fixed without using a frame, and soft materials are laid between the laths of the crate.

For the use of external insulation, houses with an attic or a technical floor are suitable. It is important that the communications passing through the technical floor do not interfere with the laying of thermal insulation. For external insulation more often use expanded clay. The material is poured between wooden blocks laid on the floor. Be sure to make steam and waterproofing layer, because a wet insulation loses half of its thermal insulation qualities.

Important! So that when walking on the technical floor, the heat insulator is not damaged, it is covered with a boardwalk or a cement screed is made.

Consider the most popular types of thermal insulation materials used to insulate an apartment.

Mineral wool

Two types of mineral wool are suitable for thermal insulation of an apartment:

Glass wool is inexpensive, easy to install and durable. However, the material emits small sharp particles that penetrate the human respiratory tract, so it is used for outdoor styling.
Basalt wool differs in ecological cleanliness, resistance to mechanical damage, strength and durability. This non-combustible material with low water absorption and good vapor permeability is allowed to be mounted from the inside of the room. When laying, frameless technology can be used. The material is allowed to be used in rooms with increased requirements in terms of fire safety.

Important! The coefficient of thermal conductivity of mineral wool is 0.041, the vapor permeability is 0.48, and the density is from 20 to 220 kg / m³.

Among the positive qualities of mineral wool are the following:

environmental friendliness;
low thermal conductivity;
basalt wool waterproof;
good vapor permeability;
durability;
fire resistance;
low thermal conductivity;
resistance to deformation and chemicals.

The only disadvantages are glass wool. The material generates a lot of dust during transportation and installation. When wet, it loses some of its thermal insulation qualities.

Styrofoam

Insulation of the ceiling in an apartment with Penoplex is most often used. This type of extruded polystyrene foam is produced by Technonikol.

Generally for thermal insulation concrete floor suitable types of polystyrene:

Styrofoam, made using non-press technology, is the cheapest material. The water absorption of this variety is the highest, and the thermal insulation characteristics are slightly lower than that of the second variety.
Press foam has closed pores in its structure, therefore it has low thermal conductivity. It is quite strong and dense.
Extruded polystyrene foam consists of small closed cells. Its thermal insulation characteristics are the highest.

Thermal insulation of the ceiling with extruded polystyrene foam has many advantages:

surface water resistance;
high efficiency;
acceptable price;
simplicity and speed of installation;
resistance to deformation;
light weight;
service life reaches 30 years;
resistance to rot and mold;
well absorbs impact noise.

All polystyrene foams ignite easily, but the extruded variety is considered a self-extinguishing material. For gluing polystyrene boards to the ceiling, only adhesive mixtures, which do not contain solvents aggressive for polystyrene. Also, the disadvantages of polystyrenes are considered to be their low vapor permeability and bad defense from sound waves propagating through the air.

Important! Water absorption of foam plastic is 0.4-4%. Vapor permeability coefficient 0.019-0.015. Strength 0.4-1 kg/cm³. Extruded polystyrene foam has the best performance, so it is used more often.

Expanded clay

Expanded clay granules are obtained in the process of firing shale clay. When heated, the surface of the granules is sintered, pores appear inside, which are responsible for the high thermal insulation characteristics of the material. For external insulation of the concrete floor, expanded clay of small and medium fractions with a granule size of 1-2 cm is used.

Advantages of thermal insulation of floors with expanded clay:

Expanded clay granules are non-combustible. They do not smoke and do not emit toxic substances during a fire. The material does not support combustion and does not drip when heated, so it is classified as fireproof insulation.
This lightweight insulation does not load the floors.
The granules are biologically and chemically resistant. They are not afraid of rodents, insects, rot and mold.
This durable material has an impressive service life (up to 50-60 years).
Installation can be done with your own hands, because this does not require special skills and devices.
The heater is inexpensive, which is also its advantage.

The disadvantage is the dusting of the material during installation and transportation. In addition, the granules are hygroscopic, therefore, after getting wet, they lose 50% of their thermal insulation qualities. That is why when installing expanded clay insulation Special attention give the device steam and waterproofing.

The cost of insulation

If you plan to order ceiling insulation, the price for the work depends on the method of installation of the material and the heat insulator used. In the process of insulating the ceiling surface, various works are carried out.

The total cost of installing a heater consists of the following indicators:

Preparation of the ceiling surface (removal of the old finish, impregnation with an antiseptic, primer) costs approximately $ 1 / m².
For the installation of a carrier crate on the base ceiling, you will have to pay $ 2.8 per square.
Laying a vapor barrier membrane - $ 1.5-2 / m².
Installation of mineral wool from the side of the dwelling - $ 6.7-7.5 per square.
Mineral wool insulation from the outside of the ceiling - $ 4.8-5 / m².
Insulation of the ceiling frameless technology(fixing plates on dowel-nails) - $ 7-8 per square meter.

After doing internal insulation ceiling surface of the insulating material close finishing. Drywall is usually mounted, but wooden and plastic panels, ceiling tiles. If a Finishing work will be performed by professionals, then the payment for their work should also be added to the cost of insulation.

Insulation of the ceiling in the apartment is more necessary for outer floors of the house. Above the ceilings of the upper floors are or unheated technical lofts, or flat roofs. Here it is necessary to heat and soundproof the ceiling, choose a material that meets these requirements.

Insulation of the basement ceiling or basement, relevant for lower floors. Here, the cold penetrates through the ceilings of basements and socles of buildings. This also applies to private houses.

It is not always possible to insulate an apartment from the side of the basement, attic or roof. More often it is necessary to insulate the apartment from the side of the floor of the lower floors and from the side of the ceiling of the extreme upper apartments.

Insulation of the ceiling of an apartment from the inside for residential premises has a number of requirements SNiP 23-02-2003 "Thermal protection of buildings", a SanPiN 2.1.2.1002-00 determines the sanitary and epidemic requirements for residential buildings and premises. With the rise in prices for space heating, the demand for the service of insulating the ceiling of an apartment has increased, especially from residents of the outer floors. The main part of heat losses just falls on the ceilings and basement ceilings. Ceiling insulation from the attic side and from the floor side are similar.

Old housing stock - apartments built in the middle or end of the last century have attic floors, insulated bulk materials: expanded clay, slag, which, although durable, in comparison with light heat-insulating materials, lose in terms of heat-insulating performance and exert an increased load on the attic floor.

Overhaul and reconstruction of such ceilings include diagnostics of load-bearing structures, replacement, and thermal insulation. The same reconstruction is carried out in private houses, when the roof is redone and attic space under the attic.

Attics have floors in the form of concrete slabs, or floor logs, to which a draft floor is mounted, and between the logs it is filled or laid thermal insulation material. A budget option- this is to increase the thickness of the layer with backfill bulk materials on previously installed insulation. Expanded clay, slag, cellulose are covered with an even layer. The second option is laying insulation between the lags. it classic version which is suitable for both concrete and wooden floors.

(2) - the insulation can be any, if the attic is non-residential, if it is an attic, then the insulation is chosen from environmentally friendly materials: basalt wool, cellulose, eco cotton wool, expanded clay. Logs (5) are made of edged board 40 x 150 mm, impregnated with substances from decay.

Vapor barrier material(6) are placed below and above the insulation. Typically, the logo on the films is applied on the side that does not allow steam or moisture to pass through, but if you don’t know which side to lay the film on, contact the seller. Instructions are attached to the film materials. Instead of a membrane film (it is expensive), a regular one is laid on the stove polyethylene film or parchment. On top of the insulation, a film is needed if it is a living space.

How to insulate the ceiling in the apartment

For attic room more attention is paid to the ceiling under the roof, here there is a heat leak in winter and overheating of the attic in summer. insulation attic floor rather plays the role of sound insulation, and therefore the counter rail (3) serves to cushion and create a gap between the vapor barrier and the floor. This gap is necessary for ventilation and evaporation of moisture from the insulation. If it is a cold attic, then ladders for walking are placed on top of the logs.

Insulation is chosen according to three indicators: density, thermal conductivity coefficient l -lambda and price.

Efficient in degree thermal conductivity are materials. in which l - 0.03 - 0.06. The density of these materials is expressed in kg/m3.

For price and thermal conductivity the best heaters are: mineral wool (glass wool, stone wool and slag wool), cellulose, foam plastic. Expensive heaters: wood fiber, polyurethane foam, cork. Insulation on the ceiling is chosen from two functions: heat and sound insulation of the ceiling. These criteria are met by board materials of medium and high density. Thermal insulation of the ceiling in the apartment is carried out with environmentally friendly materials that do not support combustion.

Insulation of the ceiling of an apartment on the top floor is sometimes performed not only because of heat leakage in winter, but also because due to heat the temperature during the day in the room reaches +30 +40 degrees and the cost of air conditioning devastates the owner's wallet.

Step-by-step instructions for insulating the ceiling in the apartment from the inside

The ceiling of the concrete slab is prepared as follows before gluing PAROK panels or other medium density slabs.

With a metal scraper or brush, remove peeled plaster, paint from the ceiling. Then cracks and cracks are puttied, a primer is applied. After that, an adhesive solution is prepared from a dry mixture in a container. Buy Typhoon quick-setting glue or another, read the instructions. With a hand mixer or a drill with a nozzle, dilute such an amount of glue that it can be consumed within 2 hours. It is not recommended to add water to the drying mixture. Dispose of the rest.

Preparing panels for gluing. On the rough side of the panel, apply adhesive solution. Then, with a comb spatula, we level the thickness of the layer. We paste the panel, starting from the far corner of the room.

In order for the panels to fit snugly against each other, it is necessary to glue in a checkerboard pattern. Between two parallel panels leave a gap of 2-3 mm narrower than the panel. Then the next panel fits snugly between them without seams.

This is what the ceiling looks like after the thermal insulation is completed.

Then there are two options, if the ceilings are high, then it is recommended to do stretch ceiling, then you do not need to stick a paint grid, putty, primer, paint. In terms of cost, these works are commensurate, but in terms of speed they are not: the stretch ceiling is completed in a few hours.

Insulation of the ceiling in the apartment is also soundproofing. The best way comply with these conditions mounting suspension system on damper suspensions with the installation of heat-insulating plates on the ceiling, laminated on both sides with aluminum foil.

Plates are easily attached to the ceiling with dowels with umbrellas. Then they are decorated with a stretch or false ceiling. This is just for the upper floors, where you have to protect yourself from radiant heat penetrating through flat roof. Aluminum foil reflects radiant energy by 90%. These panels are delivered to order, because they are hard to find in the free market.

Useful video

Let's look at specific example how to make ceiling insulation in an apartment:

If your home is located on the top floor, then regardless of the presence or absence of an attic, it will not be superfluous to insulate the ceiling of the apartment, because no one wants to lose precious gigacalories of heat. In modern houses, builders most often take care of this, but in old buildings this work is shifted to the shoulders of residents and diligent owners understand that communal payments growing is better to spend once for long-term savings.

Insulation of the ceiling from the outside

The simplest and most suitable option for preserving the volume of the living space of the room is to insulate the ceiling from the outside, that is, from the side of the attic, unless, of course, the attic space is used for communal needs and the housing office allows this to be done. In this case, the floor in the attic is cleaned, thermal insulation boards ROCKWOOL (you can additionally fix them with glue, but not necessary) and a layer of expanded clay is poured on top of them (Figure 1). Warming should be carried out, capturing part of the territory outside the apartment, and limiters (boards) are placed along the edges of the site so that the expanded clay does not crumble from the edges.

In some cases, the insulation from the side of the attic is closed with a layer of waterproofing and a screed device is made from above. This is a more time-consuming and expensive process, it is economically justified only if insulation is carried out throughout the attic, because you will not only have to buy expanded clay and insulation, but also order (knead) a screed solution and lay it on a level.

You can use not only Rockwool. But also ordinary foam. When insulating the floor of the attic (cold attic), it is not necessary to fix the insulation with butterflies - you can do with the usual adhesive composition for fastening thermal insulation boards.

Insulation of the ceiling from the inside

For interior ceiling insulation There are several ways, but any of them will “eat up” part of the volume of the living space, so before carrying out work, it is necessary to calculate their effectiveness. The best option this is a combination of ceiling insulation and lining it with drywall in decorative purposes, because in this case it is possible, having lost volume, to win in the design of the room due to new system illumination. Thermal insulation in this case is carried out between the ribs of the profile frame by attaching plates or foam close to the profile with a self-adhesive tape.

If you are interested in classic insulation without drywall, then you can go in two ways -

- Mount the frame for thermal insulation boards,
- fasten ROCKWOOL insulation or equivalent to the base of the ceiling using special "butterfly mounts" and glue.

In the first case, a distance equal to or slightly greater than the thickness of the thermal insulation retreats from the base of the ceiling, and a guide profile is attached around the perimeter of the room. Further on it, marks are made on the sides after 40-50 cm, which are connected by a ceiling profile element. It remains only to break the inter-profile niches into cells, using self-tapping screws to fix the profile, fill them with insulation and fix it to the frame ribs. From above, such a cake is closed with a reinforcing mesh for glue and subjected to a standard painting finish.

If the insulation is attached directly to the ceiling (Figure 2), then first the insulation boards are fixed to the glue, after which they are additionally pressed with “butterflies” after drilling holes with a perforator in ceiling plate(several per m2) and thermal insulation.

We recommend using LIGHT BUTTS SCANDIC 800x600x50 mm for insulation. In one package there are 12 thermal insulation boards with a thickness of 5 cm. The package is enough for 5.76 m2, and its price for autumn 2017 in Moscow is 470 rubles.

Ceiling insulation can not be called a complex and time-consuming process. Thanks to such work, it is possible to significantly reduce heat loss through the ceiling. To make the room warmer, you can use different types of heaters, each of which has its own strengths and weaknesses.

Today we will talk about ways to insulate the ceiling, and also get acquainted with the recommendations of experts.

Peculiarities

Perceptible heat loss, as well as cold air coming from the ceiling are the result of incorrectly installed or low-quality thermal insulation. Heat loss through such an overlap can reach up to 20%, since warm air rises up and needs barriers that will not allow him to leave the room.

It is recommended to deal with ceiling insulation at the stage of building a house. However, there are times when the owners, for some reason, do not perform such work during the specified period. In addition, situations are not rare when the old thermal insulation becomes unusable in an already built dwelling. And in such conditions, it will be possible to lay the insulation, but the work will be more difficult. On the this moment There are several methods for thermal insulation of the ceiling.

Many consumers are wondering why it is necessary to insulate the ceiling and whether such work can be neglected. To find out the answer to these questions, you should familiarize yourself with the main functions that the heater performs in this case:

High-quality heaters have excellent soundproof properties. Thanks to such elements, silence will always remain in an apartment or a private house, even if rain and wind are noisy outside the window.
Thanks to the installed insulation layer, the room will be warm in winter, since the heated air, rising up, will collide with an obstacle and go down again.
Ceiling insulation will also be useful in hot seasons. It will prevent the penetration of hot air into the room, so it will remain comfortable coolness.

It is also worth identifying situations in which ceiling insulation is necessary:

Thermal insulation of the ceiling should be taken care of if you have just started building a house. At this point, the ceiling consists of ordinary wooden beams. Then you can lay the insulation between them and "sew up" it.
You can also start these works if the owners have already begun to settle in the house and ceiling long time ago. This is necessary so that it is not cold in the living rooms in autumn and winter.
Thermal insulation of the ceiling is simply necessary if no one lives on the top floor of the house. As a rule, in such rooms it is always cooler. In such situations, heated areas lose their heat in favor of unheated ones.

Do not think that the thermal insulation of the ceiling can be dealt with only when arranging a private house. Such work is quite acceptable to carry out in apartment buildings.

In such dwellings, all actions can be performed only inside, and residents are prohibited from repairing attics and roofs on their own.

Currently, for the insulation of ceilings are used various materials. Each of them has its own performance characteristics from which to choose suitable option for certain conditions.

insulation requirements

Ceiling insulation must meet a number of requirements:
