How to insulate a wall inside the apartment

Warming apartments inside often becomes necessary in homes with paneled walls, as they have insufficient thickness quickly vyholazhivayutsya heating system can not fully cope with their tasks, and the room temperature drops.How to insulate a wall inside the apartment, and what methods and materials applied - this question stands before the majority of homeowners in the concrete high-rise buildings.Exterior walls in these homes particularly rapidly become cold, and often due to changes in temperature begin to dampen and covered with mold.

How to insulate a wall inside the apartment

Sometimes, when there is such a possibility, the thermal insulation of the walls carried out, since it - more efficient way to keep warm.However, this option is very costly due to the complexity of its implementation, and on their own to carry out such activities without the use of special equipment is impossible, if the apartment is located above the first - the second floor.Therefore, the decision to ins

ulate the walls from the inside, to the detriment of the overall living space. But how else , warm flat just a smaller area rather than a large cold room.Domestic work can easily be done with your hands, without the involvement of specialists.Home - pick the right stuff and have the necessary tools .

If the equipment is installed in the apartment of independent heating, the wall insulation can save energy, which are now very expensive .

compared with external insulation of walls, interior insulation of the apartment has its own quite significant disadvantages:

  • Insulated wall does not accumulate and do not delay heat , and heat loss is from 8 to 15%.
При внутреннем утеплении "точка росы" может оказаться внутри утеплителя, что ведет к его отсыреванию

For internal insulation "dew point" may be inside the insulation, leading to his soggy

  • « Dew Point" with internal thermal insulation is between the insulation and the wall, sometimes - inside the insulation layer.This leads to the formation of condensation and the appearance of mold colonies .
  • Wrong insulated inside wall will freeze all the time, and this will inevitably cause eventually irreversible destructive processes in the bulk material.

Proper insulation

to a thermal insulation layer was not formed condensate from temperature changes in winter, and, as a consequence, on the walls did not appear mildew stains, you need to carefully carry out all technological advice on warming the concrete walls inside the apartment.

Vapour barrier for internal insulation is of particular importance

Vapor with internal insulation is of particular importance

important element in the structure of the thermal insulation of the "pie" is a high quality steam.It must protect the insulation from moisture penetration, which will allow the whole structure to function effectively for a long time.

What works to achieve this goal needs to be done?

  • You must purchase a vapor barrier film high quality and water resistant sko PM to I seal the seams at the junction of her sheets.
  • for insulating layer is necessary to choose a material having a low water vapor permeability.It is desirable that this figure was lower than the water vapor permeability of the walls of the material.In this case, the moisture evaporation will take place in the street and not inside apartments.
  • at When gluing insulation, its surface is completely greased with glue using a spatula-comb , and it is very tightly to the surface of a wall, so that there was even a small cavity between them.
  • To avoid unnecessarily high relative humidity indoors, they must be equipped with additional ventilation, natural or forced type.For example, for this set of window frames valve through which the room air will flow.

  • Next, it is necessary to accurately calculate the necessary thickness of insulation.It will depend on the average daily temperature in this region in winter.The thickness of the thermal insulation material shall not be less than those of parameters, which are obtained when the product calculations, otherwise it will be broken by thermal steam balance.
  • before installing the insulation system, the walls must be treated with special primers compositions.They "prolechat" wall, will not be allowed to form on her musty colonies, as well as increase adhesion when gluing insulation.
  • Installing insulation can be started only after the complete drying of the wall.
  • We can not allow the formation of "thermal bridges" that can negate the entire process of Warming.Particularly high risk of their appearance at the junction of walls and ceilings.

What insulation and as used

For warming process walls apply several types of heaters inside.Which one to choose - solve homeowners, after he become better acquainted with their characteristics and installation methods.

Mineral wool

mineral wool - is a traditional material for insulating domestic work, but for the concrete exterior walls is necessary to choose such a kind thermoinsulator , which has a very high density - is creates vapor permeabilityand it is necessary in this case.Property wool breathable, ie ."Breathe" in this situation is likely to be harmful, since the temperature differences on the wall will be formed condensate.To avoid this it is necessary to choose the mineral wool with a high density comparable with polystyrene.

addition quality installation requires a vapor barrier.Failure to comply with all these conditions, the work will be done in vain, as after the appearance of mold and damp smell in the rooms, design have removed.Therefore, for thermal insulation of external walls, non-insulated from the street, from the use of mineral wool is better to refuse, or to apply only its dense types with the creation of the required air gap for ventilation.Read more about this - the proposed THE VIDEO:

Styrofoam

foam, polystyrene or Penoplex are more suitable for thermal insulation of external walls from the insideapartment.These materials have all the necessary properties, important of which - is the low thermal conductivity.Besides the quality of expanded polystyrene are inherent and other important characteristics that determine the possibility of its use is for internal thermal insulation works:

Экструдированный пенополистирол - отличный утеплитель, но "съедает" немало полезной площади

Extruded polystyrene - excellent thermal insulation, but "eats" a lot of useful space

  • mass of material is small, and this makes it easierinstallation.In addition, rigid and smooth surface allows a good mount it on the wall.
  • Styrofoam easily amenable to treatment - it, if necessary, can be cut using a knife construction.
  • material able to withstand the tearing force and strong compression, which often occur in the walls, such as temperature changes or shrinkage of the structure.

Since conventional or extruded polystyrene practically does not absorb moisture, it does not allow its entering the "dew point", so using this material, you can not use a vapor barrier.At the junction of walls and slabs of cold bridges can be isolated with the help of foam.Hooking plate on the wall surface can also be foam - it expands and fills all the cracks between the slabs insulation and the wall, making the surface sealed.Make a solid surface to help special locking grooves and spikes available on slabs of extruded polystyrene.

Polyurethane

Polyurethane - is one of the fo rm Sun penivayuschihsya polymer that is sprayed with the help of special equipment to the prepared wall.At the household level, almost all we met with him, if used assembly foam.

on insulated wall is fixed in advance crate of timber, which will serve as reference guides for deposited material, as well as a basis for fixing a decorative trim or lining gypsum boards.

The process of spraying polyurethane foam

process of spraying polyurethane foam

Polyurethane foam is good because it gets into all the cracks and irregularities, creating a seamless sealed surface that is dense, without any "pockets" and voids adjacent to the retaining wall, leaving cavities condensate accumulation.

This material is water resistance and has a very low thermal conductivity.When deciding to use a polyurethane foam is, we can safely abandon Hydro - and steam insulation.

Mounting foam is quick enough, but not having special equipment to produce it yourself does not work, so have invite specialists.

Thermal insulation with polyurethane foam - are very effective , but it can hold only specialists

specialists In addition to these positive qualities of this material, and can be called following:

  • After spraying polyurethane foam is quickly gaining voluminous forms and solidifies.Thus, making the installation of the insulation layer, the next day, you can safely proceed to the installation of drywall.
  • Insulation perfectly seals the "cold bridges" at the junction of planes.
  • Polyurethane has good adhesive quality of any, smooth and uneven surfaces and perfectly insulates the dew point of the penetration of moisture inside it.
  • Material suitable for thermal insulation of buildings with non-standard forms, for example, if the transition from the walls to the ceiling is constructed arches or walls are made in a curved configuration .
  • Such a coating can be any - drywall or plaster exterior finish, the choice of the owners to insulate homes.

Cork

More a material for thermal insulation, installation of which can be done independently, is a traffic jam.

Make a thermoinsulator in the form of plates or coils from the bark of oak particular species - cork.Therefore, it is an environmentally friendly insulation is a safe, which is very important for interior decoration.

Using high quality material, it is possible to solve three problems at once - is noise- - and sound insulation, as well as the decoration of the walls.

important condition for the installation of cork coverage is the evenness of the wall, so before you start gluing it is necessary to prepare the surface carefully.This proce ss etc. Gadfly follows:

  • from the wall completely cleaned off the old paint.
  • Then, the entire surface is treated with antiseptic primer that will protect the wall from mold or mildew lesions.
Levelling plaster walls

Alignment wall plaster

  • next stage of the surface must be leveled with plaster.
  • can ennoble and plasterboard walls, but in this case, the sheet should be completely missed a waterproof adhesive or sealing foam, so that it does not remain under the void.Plasterboard firmly pressed against the wall, and further fixed by anchor fixings or plastic "fungi".
  • can stick a cork on the dry wall.For this special use, intended for the same purpose adhesive.

The positive qualities of the material, in addition to its environmental friendliness, low thermal conductivity and good noise absorption include:

  • ease of installation of cork wall coverings subject to accuracy in the work.
  • Aesthetically attractive respectable.
  • Always warm and pleasant to the touch surface material.
  • Variety release forms, textured patterns and hues.
