How to insulate the apartment from the inside? How to insulate a cold apartment?

How many people would like to know how to insulate an apartment with their own hands? The old Soviet-built houses are mostly thermally insulated badly. Systems of central heating in them are very worn out. On how to properly perform a similar job, and talk later in the article.

Stages of insulation

How to prepare an apartment for the winter? The order of work in this case should be as follows:

• Warming of windows and doors.
• Replacement of old radiators.
• Wall insulation.
• Warming of the ceiling and the floor.
• The device of effective ventilation.

So, let's figure out how to insulate the apartment, in more detail.

Insulation of windows with rubber bands

The answer to the question of how to insulate an apartment depends, in part, on how tight the windows are in it. Of course, the dried up wooden designs are best replaced with new plastic ones. However, sometimes it happens that there is not enough money for this. In this case, it is necessary to insulate the old windows. How to do it right? There are several methods of insulation of such structures:

• Use of sealing rubber bands.
• Fixing slots between the frames.
• Gluing strips of fabric, paper or tape.

Sealing gums are sold in hardware stores and are narrow bands of foam rubber or one of the varieties of soft polymer. The insulation with their help is extremely simple. The tape is attached to the frame by means of an adhesive layer on it. Doing this procedure, you should try not to stretch the material.

Insulation with caulk

Asked about how to insulate the apartment inside, you should also pay attention to the gap between the frames and the opening. Sometimes they are very wide. The use of a sealant in this case may not help. Big cracks are best to digest. To do this, you can use rags, pieces of foam rubber or even just paper. Over the caulk, all surfaces should be sealed with a paint tape or tape.

Use for sealing windows of putties

On the question of how to properly insulate the apartment by sealing the windows, there is another answer. Close slots can be using specially designed for this putty. Such mixtures are applied by means of a metal spatula. Recently, transparent seals have also been used for the insulation of windows. The technology of insulation in this case does not differ from the way of isolation of ordinary alabaster putty. In the event that the sealant inadvertently gets on the glass, you do not need to erase it. Remove it with a sharp blade after hardening.

Replacement of radiators

Cold in high-rise buildings is also due to the low efficiency of old radiators. Therefore, wondering how to insulate the apartment, of course, it is worth thinking about also their replacement. Do this in the warm season, before the start of the heating season. The order of execution of work in this case is as follows:

• Cut old radiators.
• On the wall, marking is done, the brackets are nailed.
• A new battery is hung on the wall. On all four of its outlet branch pipe are screwed nuts, coming in the kit.
• Next to the two of them (diagonally above and below) with the winding of the patch and smearing the thread paste, the inlet and outlet cranes are screwed.
• Opposite the first one, on the back of the radiator, the Maevsky crane is installed.
• The remaining nozzle is closed with a special plug.

The method of connecting radiators described above is called diagonal. There are also lateral and with a lower mount. In the first case, both cranes - both the input and output - are screwed on one side of the battery, at the top and bottom. The air vent and the plug, respectively, are installed on the other. With the lower connection, both valves are mounted on the right and left to the lower nozzles. The Maevsky crane is always installed opposite the coolant supplying element.

How to increase the efficiency of heating batteries

How to insulate the apartment with your own hands by replacing the radiators, you now know. Next, we will give a few tips on how to make their work more effective. So:

• If your apartment is cold, in no case can you close the batteries with decorative panels.
• When placing the radiators in too deep niches under the windows, they will be much worse.
• From the wall, the battery should be approximately 5 cm away, and not less than 10 cm from the floor and the window sill.

Insulation of walls with mineral wool

Thus, we have discussed how to insulate an apartment from the inside by closing windows and a balcony door, as well as replacing radiators. Next, consider how to properly isolate the walls. This procedure consists of several stages:

• The walls are thoroughly cleaned from dust and dirt.
• Mounted lath under the sheets of gypsum board. The easiest way is to make it out of a beam of width corresponding to the thickness of the insulation.
• Plates of mineral wool voraspora are inserted between the curbs.
• Further they are additionally fixed to the wall with dowels-"fungi".
• A vapor barrier film is stretched over the insulated heater plates . When insulating the room from the inside , the dew point, unfortunately, is inside the walls themselves. Therefore, the insulation material must be carefully protected from the formation of condensation on it. For this purpose, vapor barriers are also used. It can be a usual thick polyethylene film or some of its modern substitutes. Strips of the vapor barrier are fixed horizontally, starting from the bottom. Fix them to the crate with thin bars.
• Next on the resulting controllabel are mounted sheets of gypsum board.
• At the final stage, the walls are painted or wallpapered.

Insulation of surfaces with expanded polystyrene

There is one more answer to the question of how to insulate an apartment from the inside by covering the walls. This can be done with rigid expanded polystyrene plates. The walls are also thoroughly cleaned, degreased and primed. Then they are glued on the plates of expanded polystyrene. In this case, special glues intended for foams are used. The lining is not stuffed. The plates are fixed to the wall at random. Begin installation from the bottom - off the floor. In the corners of the plate cut to the required width with a sharp knife. In addition to the walls they are fixed with dowels - "fungi". Next, all the joints are closed with white foam. After that, the surface of the walls is covered with a special glue composition, into which the reinforcing paint net is pressed . At the final stage, the walls are finished with decorative or ordinary plaster.

Use of foam plastic

Sometimes insulation of apartments is carried out and polystyrene. This material has a low degree of thermal conductivity and is very inexpensive. The answer to the question of how to insulate the apartment with a foam plastic is also not too complicated. The order of the work in this case is exactly the same as for the insulation of surfaces with expanded polystyrene. The only thing is to handle the sheets of polystyrene as carefully as possible. The fact that they can be very easily broken.

How to insulate the ceiling

Of course, the answer to the question of how to insulate an apartment inside effectively depends on how well the ceiling is able to keep heat. In particular, this applies to apartments located on the last floors. The method of insulation of ceilings is absolutely no different from the method of wall insulation. The only thing - in this case, you need to pay maximum attention to fixing the plates to the surface. If you can not use the "fungi" for wall insulation, then when installing the insulator to the ceiling their use is considered mandatory. Otherwise, the plates just fall.

How to insulate the floor

The question of how to insulate an apartment with one's own hands, in the event that it is located on the ground floor, also boils down to how to insulate the floors. To do this, first remove the finishing. Then remove the old boards. Open lags need to be smeared with antifungal and raise the fire-resistant properties of wood compounds. Then between them, the heater plates are laid. In this case, you can use both mineral wool, and polystyrene or expanded polystyrene. The thickness of the insulation must be slightly less than the width of the lag. This is necessary in order to finally have an air gap between him and the new floorboard. At the next stage, a vapor barrier is mounted over the insulation. Attach it to the lags on thin slats (two on each side). Next proceed to the packing of the board.

In the event that you are wondering how to insulate a corner apartment, the insulation of walls, floor and ceiling will be the best answer to it. The fact is that in such rooms the structures freeze much more than in conventional ones. In particular, this applies to angles.

Ventilation device

So, how to insulate a cold apartment, you now know. However, after the walls, floor and ceiling are isolated, the room can become stuffy and damp. Therefore, in the final stage, it is necessary to take care of the device for effective ventilation. The simplest option is to buy a ready-made system. However, such equipment is very expensive. Therefore, in a standard small apartment, you can use a slightly different method of ventilation. To do this, before installing the insulation in the external walls under the windows drilled holes about 10 cm in diameter. Exactly the same will have to be done in the "pie" of the wall warmer.

Check the correct operation of the common ventilation shaft can be very simple. To do this, you will need to bring a lighted lighter to the grilles in the kitchen and toilet. If the flame starts to deviate noticeably from the vertical axis, then everything is in order. The ventilation is working properly. If this does not happen, you will have to contact the management company and call specialists for verification.

We hope, now you are more or less clear how to insulate an apartment in a multi-storey building with your own hands correctly. Having completed all the measures described above, you can make your home as comfortable as possible for living in the cold season.

How to insulate an apartment outside

Since the method of isolation from the outside is considered much more effective, despite the complexity of implementation, sometimes it is used for insulation. However, you can conduct such a procedure yourself only when the apartment is located on the first or at the extreme on the second floor. To isolate the premises located above, you will have to call specialists. Next, let's look at how to insulate an apartment from the outside in stages:

• First of all, the crate is stuffed on the walls.
• Further, the plates of the heat insulator are inserted between the beams.
• The walls are covered with a waterproofing film with fastening to the bars.
• The siding is siding.

It is very important when installing insulation plates to ensure that they necessarily overlap all joints along the perimeter of the apartment.
