When it comes to warming the walls of the building, experts unequivocally recommend that the installation of the thermal insulation machines from the outside, external insulation of the facade of the building is much more effective than the internal one. But in conditions where it is not possible to get close to the cold outer part of the wall - for example, elevator shafts, cold access, archways, impossibility to disrupt the aesthetics of the facade appearance - the inner insulation layer is the only possible option.
A few rules that must be adhered while installing cool insulation machines
will help to avoid annoying mistakes, the consequences of which are usually expressed in minimal efficiency, in wet and cold walls and high humidity of premises.
The main factor for which it is necessary to "fight" is to move the dew point (condensation loss) as far as possible to the facade, and ensure a sufficient level of ventilation of the insulating layer. With such tasks fiberglass insulation blowers
and polyurethane foam - compared with the previously popular mineral wool these materials are much more effective by all criteria.
Avoiding, or trying to minimize the loss of condensation in the heat-insulating layer
Creating a vapor barrier - producers offer foams for vapor barrier, they should be laid without the slightest gaps, it is necessary to seal all joints;
The vapor permeability of the material used in cool insulation blowing machines
for insulation - the lower the indices, the better, as long as the vapor permeability of the wall is higher - the vapor will escape;
The wall must be dry, pretreated with antibacterial composition;
Plates of thermal insulation should not be glued "beacons" (several blunders around the perimeter of the square and center), the adhesive should be applied to the entire plane, and it is desirable to use a needle roller and a notched trowel.
It is also important to choose the thermal insulation material depending on which walls will be insulated - the thermal conductivity of the brick and concrete is significantly different, as are the nuances of the technological process of installation.
Internal wall insulation, work order
Specialists recommend: for the insulation of brick walls, mainly use foamed expanded polystyrene plates, this material is characterized by low thermal conductivity, resistance to the appearance of mold, fungi, and it is not flammable and environmentally friendly.
To work on the insulation of the concrete wall, extruded polystyrene foam is used, the thickness of the insulation is calculated by the formulas, and it is also necessary to take into account the peculiarities of the climatic belt, the location of the apartment in the house.
Algorithm for the installation of an internal insulation layer
Brick masonry is cleaned, plastered, then putty is applied, the concrete wall is in two layers, then applied primer;
It is mandatory to lay water proofing materials, pre-treated with antiseptic walls;
It is important when laying the plates of expanded polystyrene, it is necessary to treat the joints with a sealant and apply the adhesive solution to the surface of the plate with a uniform thin layer;
Then the reinforcing mesh is put on the slabs with the help of adhesive composition (it is heated), it is sanded after drying.

For better sound insulation, the different blades (glass and gas) that make up the double or triple glazing must be of different widths (asymmetrical glazing).
