What materials for thermal insulation can I use?
As the insulation of apartments from the inside requires the material not only high values for thermal insulation characteristics, but also environmental friendliness, then the most optimal option will be mineral wool. At the heart of its production are exclusively environmental materials, which makes it so popular.
Warning! When working with mineral wool, you must arm yourself with respirators and protective gloves!
If you started outdoor insulation of apartments, then the most suitable for these purposes will be polystyrene foam. Its main advantages include:
- low price;
- the convenience of working with the material, it is easily amenable to cutting or other actions of the builder;
- no difficulties in getting to the destination;
- durability and various options for the subsequent finishing of the material.
If so to understand, then the material is suitable for internal thermal insulation activities. At the same time, the algorithm for performing the procedures is practically the same. The only thing that needs to be paid attention is the use of materials suitable for outdoor or domestic work.
How to insulate an apartment from the outside?
In order to produce a quality insulation of the apartment from the outside, it is necessary to ensure that you have purchased all the necessary materials and prepared tools. So, you will need:
- polystyrene plates or other material that you will use as a heater;
- primer mixture of deep penetration;
- special adhesive for styrofoam;
- profile starting to clearly highlight the bottom row of insulation;
- dowel-nails and special fixings for foam plastic( "fungi");
- fiberglass reinforcement mesh;
- dry plaster mixture for finishing works;
- corner reinforced.
In addition, you will probably need a puncher, a hammer, pliers, a nozzle for a drill in the form of a mixer, as well as spatula and conventional spatula for applying the plaster mixture. When all this is, you can proceed.
First, we clean the surface of old finishing materials. After that, the surface is carefully ground. When the wall is dry, the starting profile is fastened to the lower edge of the surface, on which the first strip of insulation will be laid. To do this, a uniform layer of adhesive composition is applied to the sheet using a notched trowel. Further, the foam is pressed tightly against the surface, after which it is fixed in "fungi" at five points.
When the entire surface is finished, a plaster layer is applied to the foam, into which the reinforcing mesh is heated. After that, you can apply another 1-2 layers of plaster to maximally qualitatively prepare the surface for subsequent finishing works. By the way, the technology of laying heat insulation material is exactly the same as for internal insulation.
Warming inside the apartment
This process, like internal insulation of housing, we will look at the example of the use of mineral wool, because it is most suitable for such works. In order to complete the procedure, you will need:
- mineral wool;
- wooden bars or metal profiles for drywall;
- fixing the "fungus";
- primer.
As usual, we immediately start preparing the walls for insulation.
Important! To ensure that the insulation is of the highest quality, make sure that all cracks and other openings on which the cold air can enter are embedded in the surface to be treated!
After this, the wall is carefully grounded. When the surface is dried, a guide profile is stuffed onto the floor and ceiling, into which a rack profile is subsequently inserted. The distance between the posts should not exceed 40-60 cm.
Attention! Do not forget to leave a distance between the pillars and the wall, which would be enough to lay the heat insulator.
When the frame is ready, the insulation is laid. Please note that there are no passes. This will nullify all your efforts, because it is through the holes in the apartment that a stream of cold air will flow. The material is fixed to the surface with the help of "fungi".Further, the whole thing is sewed with plasterboard, which then undergoes further processing. But this is a completely different story!
