The increase in energy prices for many property owners has made it urgent to find alternative ways to improve the energy efficiency of the house. Warming the facade of the house with foam plastic can significantly reduce the cost of heating the room. In addition to thermal insulation, this coating additionally protects the walls from destruction and deformation. In this way it is possible to insulate the walls not only of a private house, but also of an apartment building. Sam polystyrene poorly transmits heat and prevents the passage of moisture.
Do this yourself will not be difficult, foam is inexpensive, eco-friendly, does not rot, does not weight the wall. The material does not require special skills when laying. But you need to take into account that insulation with foam is an intermediate procedure in the decoration of the facade. After that it will be necessary to make it plastering with any kind of facade plaster you like .
Materials for facade insulation with foam:
- Styrofoam;
- metal for forests;
- adhesive for foam plastic;
- dowels - umbrellas;
- drill;
- reinforcing mesh;
- putty knife;
- a deep penetration primer and a brush;
- decorative plaster;
- saw.
Thermal insulation technology
- Before the beginning of the work, the walls are maximally leveled, all cracks and crevices are embedded, the surface is grounded and cleaned. Smooth walls will ensure the beauty of further coverage, since with the help of sheets of polystyrene foam, it will almost be impossible to level them.
- A reliable stage is installed to access the entire surface of the wall and work at height.
- Holes are prepared.
- Below the walls are fixed base plates to prevent the foam from sliding down. Prepares the glue and is applied to the insulation in several places along the perimeter and in the center.
- The sheet is pressed against the wall and leveled in two planes.
- In the door and window openings reinforced mesh is laid.
- Proceed to the next sheet. They are glued in a checkerboard pattern like brickwork. In the openings the sheets are cut out along the perimeter. Saw foam can be a hacksaw. Clearances between sheets should be done as little as possible.
- It is necessary to wait for the material to dry for about three days. Then sheets of polystyrene are additionally fastened with special dowels with hats at the rate of five pieces per square meter of surface. The length of the umbrella should be two widths of the foam. It is most convenient to fasten the dowels in the corners and in the center of the sheet.
- The reinforcing mesh is laid on corners, walls and covered with a layer of glue with a spatula. This will strengthen the corners of the building and the finish layer. To strengthen the corners, you can also use a metal corner.
- Further the wall from above is covered with plaster, which is carefully smoothed. One layer of plaster is not enough. The next day you need to apply another one.
- The surface is primed and covered with a decorative colored texture. As a finishing finish, plaster was chosen as bark beetle. It contains particles of minerals. After smoothing it with a spatula on the surface, the furrows are beautiful.
- Finishing of the facade is finished.
Thermal insulation of facade walls with foam reduces the heat exchange between the street and the house. Such a finish will make the room much more comfortable. Exterior finish will not allow the penetration of cold into the house, and the walls in it will remain dry and warm. Dampness and fungus now they will not be scary. This version of insulation - the most affordable and popular.
