If you are thinking about insulating the walls of a house or apartment from the inside, it is important to remember several important nuances.
- The area of a room that has been insulated from the inside may become significantly smaller, because several centimeters on each wall will be “taken away” by the insulation material;
- If the thermal insulation process is not performed correctly, fungus and mold may appear in the house. To prevent this from happening, it is important to provide a ventilation system;
- Insulating an apartment or house is only possible if all objects and furniture are moved out of the room.
Don't these requirements scare you? Then insulating your apartment from the inside is for you.
How to insulate walls from the inside
Before starting the installation, you need to treat the surface of the walls from mold and fungi, and then choose a high-quality vapor barrier film. After that, you need to ensure tight sealing of the joints and remove excess plaster, chips or other small things that can reduce the effectiveness of the insulation.
When gluing insulation to the wall, you need to make sure that it adheres to the surface as tightly as possible. Experts advise installing special valves on the windows to reduce the humidity level in the room.
Once you have prepared the walls, you can start installing the insulation material. The most common type of insulation is expanded polystyrene, which is quite easy to work with. Installation does not require additional vapor barrier, which makes the task easier.
First, you need to level the surface - remove irregularities and fill cracks. Then apply glue evenly to the wall, and then spread the glue around the perimeter and center of the polystyrene foam board. After that, you need to press the material tightly against the wall, carefully pressing it with your hands.
It is important to treat all joints with mounting foam so that there are no holes left. To improve the effect, use dowels - five per plate. Next, it remains to finish and finish the surface.
