Styrofoam wall insulation is currently a very popular way to make living in a house with freezing walls more comfortable, while also reducing the costs associated with heating a home. This operation is performed in several main stages, each of which is very important.
First of all, prepare the surface. If we are talking about the outer walls, then there should be only plaster without any decorations. It is necessary to walk on them only with a primer with an aquastop. The following is the measurement and selection of the necessary materials. Everything is quite simple here, you need to measure the height and width of the walls, and then subtract the parameters of window and door openings from these values. In addition to polystyrene, corners are also needed to strengthen the corners and align them, a plastic paint mesh, with which the putty will be reinforced, special dowels,that will be required to attach 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 plastic, then we should separately address the issue of choosing this material, as well as glue for it. It is not difficult to decide on glue, you need to buy it with the calculation of 25 kilograms per 3 square meters of 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 use, the densest material with a thickness of 50 millimeters is suitable.
Insulation of walls with foam plastic can be called a fairly easy process that does not take too much time. First you need to knead the glue in some container. Then you can apply it to the foam sheet with a tile spatula in an even layer, and then walk with a comb, which will achieve uniform application. On the wall, do the same. After that, 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 with special dowels, with one mount 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 do-it-yourself wall insulation with foam plastic does not end there,This is followed by a more difficult stage - putty. To begin with, it is necessary to stick a metal paint corner on all corners and slopes, since these vulnerable spots need the most active protection, in addition, after such a procedure it will be much easier to putty. You should smear glue on the corner, drown the corner in it, and then align it using the rule.
Do-it-yourself wall insulation at this stage is a little more 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. A smooth and even surface can only be created by applying several layers.
It is worth saying that wall insulation with foam plastic allows you to save up to 30% of energy spent on heating, and this is a fairly good indicator.
