Thermal insulation of walls at the moment is a very popular way to make living in a house with freezing walls more comfortable, while also reducing the costs associated with heating the home. This operation is performed in several main stages, each of which is very important.
To begin with, it is worth preparing the surface. If we are talking about external walls, then there should only be plaster without any decorations. You need to go through them only with an aquastop primer. The following is the measurement and selection of the necessary materials. Everything is quite simple here, it is necessary to measure the height and width of the walls, and then take away from these values the parameters of window and
door openings. In addition to polystyrene foam, corners are also necessary to strengthen the corners and align them, a plastic
masking net with which the putty will be reinforced, special dowels that will be required to fasten the foam sheets, they are usually taken at the rate of 6 pieces per square meter.
If we consider the
insulation of walls with foam, then we should separately address the issue of choosing this material, as well as glue for it. It is not difficult to determine the glue, you need to buy it with the calculation of 25 kilograms per 3 square meters of the surface, and this is based on the fact that it will be used for gluing and puttying. Next, you should choose a foam, and here it is important to know that it can be different in density, and its cost depends on this. For outdoor work, the most dense material with a thickness of 50 millimeters is suitable.
Warming the walls with foam can be called a fairly easy process that does not take too much time. First you need to mix glue in some container. Then you can apply it on a foam sheet using a trowel with a uniform layer, and then go with a comb, which will achieve uniform application. On the wall, you should do the same. After this, the foam can be pressed against the wall, it is good to knock on it, this can be done with your hands or with a special device. Next, the sheets should be fixed by means of special dowels, with one fastening being placed in the center, and the other four in the corners. Similar actions are performed on the entire surface, which should be insulated.
It is worth saying that the insulation of the walls with foam with your own hands does not end there, then the more difficult stage follows - puttying. First you need to stick a metal
paint corner on all corners and slopes
, since these vulnerabilities need the most active protection, in addition, after such a procedure it will be much easier to putty. Spread glue on the corner, drown the corner in it, and then level it using the rule.
Doing warming the walls with your own hands at this stage is a little complicated, since it is necessary to apply a thicker layer of putty than usual, this is done so that a special mesh for reinforcement can be drowned into it. To create a smooth and even surface is possible only by applying several layers.
It is worth saying that wall insulation with foam allows you to save up to 30% of the energy spent on heating, and this is a pretty good indicator.
