It should be noted that one of the most frequent cases is the insulation of the corner apartment, as the external environment captures a large area. It is necessary to take into account the fact that in this sense the lower and upper floors suffer, so we will stop further and at this point( see photo, video).

How to insulate the wall in the apartment

First of all, one of the current methods of insulation is chosen. At present, two materials are most in demand: polyurethane foam and expanded polystyrene. These are synthetic materials with high characteristics - thermal insulation, water repellency, elimination of biological activity( that is - no mold appears, no insects are planted).Sometimes a combination finish is used: two dissimilar layers. The latter method has many controversial points, but at the same time such warming is called the most powerful.

Important!- the inner plane of the wall must be as dry as possible. Therefore, it is recommended to perform work in the warm season or in a stable warm room( which is rare).

The wallpaper is removed from the wall, grinding and leveling takes place. From the cleanliness and evenness depends on how well the insulation is applied. Used sandpaper and other auxiliary tools, brushes, etc. Specialists advise paying particular attention to those parts of the walls that were affected by mold or darkened from dampness.

Next, the surface is treated with antiseptics. These are special solutions for the removal of mold, fungus. It is difficult to advise something concrete, since the choice of such liquids and mixtures is great. Masters are advised to give preference to those with which you can least contact( no need to pour, stir, etc.). This is due to the fact that the chemical composition of the means is quite active.

Next, you need to let the walls dry out. The next step is priming. It is recommended to use primers with deep penetration, as only in this case a satisfactory result can be guaranteed. Plaster is applied evenly, then it must dry naturally. In some cases, a second primer is produced.

In the case of polyurethane foam, a special formwork is installed, divided into cells, in each of which a quick-drying foam is poured. This method is not recommended to implement independently, because you need an understanding of technology and experience with foam.

Expanded polystyrene Penoplex is a plate with a thickness of about 5 cm. The mortar for fixing the plates is not used. Need special glue, and it must be applied evenly across the entire plane of the plate. Only in this case the moisture will not penetrate into the room. In some cases, use as an anchor dowels-umbrellas, for this plate is applied to the wall and 4 holes are made at the corners, then dowels are inserted. This fastening is quite reliable. We use a large spatula, we apply the solution with a uniform, non-thick layer. After the wall is dried, we process it with sandpaper. Then apply a primer. Everything, now the wall is ready for plastering - you just need to wait for complete drying.

Insulation of the floor in the apartment

We examined the incomplete insulation of the apartment with our own hands, as it left to touch on one more question: how to insulate the apartment on the first floor, where often faced with such an unpleasant phenomenon as the cold floor. We will not go into this issue deeply, we will define only the main types of materials that are used. Mineral, wood-shaving insulation, polymeric. Thermal insulation with expanded clay is one of the most common methods. Before the insulation is waterproofed, then the beacons are installed, the expanded clay is filled, the concrete screed is poured.
