How to insulate a wall inside an apartment

Contents of the

foiled material compared to the outer thermal insulation walls, internal insulation apartments has enough significant drawbacks:

• Insulated wall does not accumulate, and no delays heat , and heat losses ranged from 8 to 15%.

With internal insulation, the "dew point" can be inside the insulation, which leads to its dumping.

• " Dew point" with internal thermal insulation is located between the heater and the wall, sometimes - inside the insulating layer. This leads to the formation of condensation and the appearance of mold colonies .
• Incorrect insulated from the inside the wall will freeze all the time, and this inevitably causes irreversible destructive processes in the thickness of the material over time.

Correct insulation

In order to avoid condensation from the temperature drops during the winter period under the thermal insulation layer, and as a result, mold spots did not appear on the walls, all technological recommendations for insulation of concrete walls from inside the apartment must be carefully followed.

Steam insulation for internal insulation has a special significance

An important element in the structure of a thermal insulating "pie" is a high-quality vapor barrier. It should protect the heater from moisture penetration, which will allow the entire structure to effectively perform its functions for a long time.

What kind of work is required to achieve this goal?

• It is necessary to purchase the high-quality vapor-proof film and waterproof fasteners for and seal the seams on the connection of its sheets.
• For a thermal insulation layer, a material having a low vapor permeability must be selected. It is desirable that this figure is lower than the vapor permeability of the wall material. In this case, the evaporation of moisture will occur in the direction of the street, and not inward apartment.
• When glues the insulation, its surface is completely smeared with glue using the spatula, and it is very tight against the wall surface, so that there are not even small cavities left between them.
• To avoid the occurrence of excessively high relative humidity indoors, they must be equipped with additional ventilation of natural or forced type. For example, for this purpose, valves are installed on the window frames, through which air will enter the room.

• Next, you need to accurately calculate the required thickness of insulation. It will depend on the average daily temperature in the given to the region in the winter. The thickness of the thermal insulation material should not be less than the parameters that were obtained when calculations were performed, otherwise the steam-heat balance will be violated.
• Before installing the insulation system, the walls must be treated with special primers. They "will treat" the wall, will not allow molds on it to form on it, and also increase the adhesion of when bonding heat insulation with .
• You can start the insulation installation only after the wall has dried completely.
• It is impossible to allow the formations of "cold bridges", which can negate the entire heat insulation process. Especially the risk of their occurrence at the joints of walls and ceilings is great.

Which heaters and how to use

For the process of wall insulation from the inside, several types of insulation are applicable. Which one to choose - to solve to the owner of habitation, after it is more closely acquainted with their characteristics and ways of installation.

Mineral wool

Minvata - is a traditional material for insulating interior works, but for concrete exterior walls it is necessary to choose a kind of thermal insulator , which has a very high density - this creates vapor tightness, and it is necessary in this case. The property of mineral wool is flowing air, ie ."Breathing" in this situation, rather, is harmful, since with temperature changes on the wall, condensation will form. To avoid this, it is necessary to choose mineral wool with high density, comparable with expanded polystyrene.

Use mineral wool for interior insulation of walls with special care.

In addition, the requires a high quality installation of the vapor barrier. If all these conditions are not observed, the work will be done in vain, since after the appearance of the fungus and the smell of dampness in the rooms, the construction will have to be dismantled by the .Therefore, for insulation of external walls that are not heated from the street, it is better to refuse from the use of mineral wool, or to use only its dense types with the creation of the necessary air gap for ventilation. More about this - in the video:

Styrofoam

Styrofoam, expanded polystyrene or penoplex are more suitable for insulation of external walls from inside the apartment. These materials have all the necessary properties, main of which - is a low thermal conductivity. In addition to this quality, styrofoam has other important characteristics that predetermine the possibility of its use for internal thermal insulation works:

Extruded polystyrene foam is an excellent insulation, but it "eats" a lot of useful area.

• The weight of the material is low, and this facilitates installation. In addition, rigid and a flat surface allows you to fix it well on the wall.
• Expanded polystyrene is easy is amenable to processing - it, if necessary, it is possible to cut with a construction knife.
• The material is able to resist tearing forces and strong compression, which often occur in the walls, for example, with temperature drops or shrinkage of the structure.

Since ordinary or extruded polystyrene foam practically does not absorb moisture, it will not allow its to hit the "dew point", so using this material, you can not use the vapor barrier. On the joints of walls and slabs, cold bridges can be insulated with a mounting foam. To fasten the plates to the surface of the wall it is also possible to foam -, expanding it, fill all the gaps between the insulation plates and the wall, making the surface sealed. To make the surface one-piece, special locking grooves, and the spikes available on extruded polystyrene plates will help.

The locking groove-groove part greatly simplifies the installation of the

insulation. Having installed a number of plates, they are attached to the wall with the help of special "fungus" attachments. To do this, the assembled panels are drilled through, making a hole in the wall, and then the fasteners are clogged into it.

Fixing EPS boards to the

wall It should be noted that the foam does not muffle enough noise and this is one of its drawbacks. In addition, any of the types of expanded polystyrene combustible, to varying degrees, and upon ignition releases dangerous for the health of the human substance.

Plates of expanded polystyrene from above can be plastered or sealed with plasterboard

After installing the slabs and "sealing" all cracks and seams, the thermal insulation layer can be plastered or covered with sheets of plasterboard.

polyurethane foam - is one of the foils rm all foaming polymers that are sprayed with special equipment onto a prepared wall. At the household level, almost all met with him, if using a mounting foam.

The lath from the wooden beam is pre-fastened to the heat-insulated wall, which will serve as support rails for the sprayed material, as well as the basis for fixing the decorative finishes or the plasterboard plating.

foaming process The polyurethane foam is good for penetrating into all cracks and irregularities, creating a seamless, hermetically sealed surface that fits tightly to the supporting wall without any "pockets" and voids, leaving no cavities to accumulate condensate.

This material is moisture resistant and has a very low thermal conductivity. When deciding to use foam polyurethane, you can safely abandon the hydro - and vapor barrier.

Installation of polyurethane foam is carried out quickly enough, but not having special equipment to produce it yourself will not work, so will have invite specialists.

Thermal insulation with polyurethane foam is very effective, but it can only be carried out by

specialists. In addition to the above positive qualities of this material, we can name the following:

• After spraying, polyurethane foam quickly acquires bulk molds and freezes. Thus, by installing this thermal insulation layer, the next day you can safely proceed with the installation of drywall.
• Heater perfectly seals "cold bridges" at the joints of planes.
• Polyurethane foam has good adhesive quality with any even and uneven surfaces and perfectly insulates the dew point from penetration of moisture to it from the inside.
• The material is suitable for the insulation of rooms with non-standard shapes, for example, if the transition from the wall to the ceiling has the design of the arch or the walls are made according to the curved configuration.
• This coating can have any - plasterboard or plaster exterior finish, according to the choice of the owners of the insulated housing.

Stopper

Another with one material for insulation, the installation of which can be made independently, is a cork.

Cork - an excellent natural material for thermal insulation

This thermo insulator is made in the form of slabs or rolls from bark of a special variety of oak - a cork tree. Therefore, it is an environmentally friendly safe insulation, which is very important for interior decoration of premises.

Using high quality material, you can solve three problems - is noise - and soundproofing, as well as decorative wall decoration.

An important condition for the installation of the cork cover is the evenness of the wall, therefore, before proceeding to gluing it, it is necessary to thoroughly prepare the surface. This process ss pr is designed as follows:

• The old coating is completely cleaned off the wall.
• Then the entire surface is treated with an antiseptic primer that protects the wall from damage by fungus or mold.

Leveling of walls with plaster

• The next step is to level the surface with plaster.
• You can decorate the walls and plasterboard, but in this case, the sheet must be completely smeared with waterproof glue or mounting foam, so that there are no voids under it. Drywall firmly is pressed against the wall and additionally fixed by anchor fasteners or plastic "fungi".
• Cork can be pasted on a dried wall. To do this, use a special glue intended for such purposes.

Special glue for working with the plug

To the positive qualities of the material, in addition to its environmental friendliness, low thermal conductivity and good noise absorption, the can be attributed to:

• Lightness for installing cork wall covering while observing accuracy.
• Aesthetically attractive respectable look.
• Always a warm and a pleasant surface to touch the material.
• Variety of production forms, textured patterns and shades.

Cork is not only an excellent thermal insulator. It will give the room a special decorativeness

• The cork insulation is not thick, so it does not make the area smaller than the - , this quality differs favorably from other thermal insulation materials.

Penofol

Penofol is inherently - is a roll foam polyethylene with a thickness of 2 to 10 mm, on one side of which a foil is applied, which helps to reflect the heat of inside premises.

Penofol - foamed polyethylene with foil-coated

• Before its installation, the surface is prepared in the same way as under the cork coating.
• On even walls penofol can be fixed using a construction double-sided adhesive tape. Material under any circumstances is located in the foil side of the room. This creates a kind of thermos for effective heat retention.
• strips of foam are stacked end to end. Between them they are glued together with a special tape, also having a foil-like reflective surface, since all coatings of must be leakproof.

The cladding is installed over foam foil laid with foil side inside the room

• Over fixed to wall of foam install crate from rails, bars or metal galvanized profiles. This cradle with with throws the base for the installation of lining or wall covering with drywall sheets. The plasterboard surface can be subsequently coated with plaster, wallpapered with wallpaper, or carefully plastered with and sanded and then dyed.
• It is very important to install a drywall or lining on top and bottom of the structure to leave a slot that will serve as a ventilation hole for air circulation so that moisture does not accumulate.

Insulation of the insulated wall with clapboard

Despite its small thickness, the foam foil is an excellent heat and sound insulator .It is used as a separate insulation, but it is quite possible to use it in combination with other materials. It attracts the simplicity and speed of laying on the walls, floor or ceiling, as well as a long period of operation.

When choosing a material for interior insulation from the inside, it is necessary to first examine all wall surfaces to which the thermal insulation will be installed. If the wall is dry and there are no mold spots on it, then you can start preparing the surface and buy a heating material. Carry out such work on an unprepared basis - categorically is prohibited . Not only will not provide the necessary effect - it is possible to thoroughly damage the apartment atmosphere, make its raw, unhealthy, as the spores of many kinds of mold or fungus are extremely dangerous to people's health, especially for those suffering x x respiratory organs or a predisposition to allergic reactions.

In general, any of the methods of insulation of apartments presented in the publication from the inside will not require any complicated additional equipment, and this technological process can be carried out independently.
