Warming of walls with polystyrene - the characteristics of the material
For what reason is foam the most sought after building material used for thermal insulation of premises? This is largely due to its characteristics. In addition, the presented product is excellent not only to produce walls with foam insulation, but also for the thermal insulation of floors, ceilings and other things. So, let's consider the basic characteristics of the foam:
- The material has a sufficiently low thermal conductivity of 0.037-0.041 W / mK, which allows using thin sheets of this product for insulation.
- The material is stable over a wide temperature range. For example, the highest temperature threshold is 180 ° C.
- Has a high resistance to external substances, for example, sea salt, cement and gypsum solutions, water-based paint and other.
- Polystyrene foam has a high moisture absorbency of 0.5-1.5% of the volume. This makes it possible to say with certainty that the styrofoam plate will not swell from moisture and will not dissolve in the air.
- The product allows to give 100% protection against the appearance of fungal formations on it. Has 100% resistance to decay.
- In addition to thermal insulation properties, the foam has noise-proof parameters.
- Easy to install and easy to install.
Materials for thermal insulation work
Attention! In order for the technology of insulation of the walls with polystyrene to take place without any delays, care must be taken to ensure that you have all the necessary materials and tools.
We bring to your attention their list:
- polystyrene;
- primer mixture;
- special reinforcing mesh;
- Adhesive for foam: the leader among dry mixes for working with expanded polystyrene plates is the company Ceresit ;
- dry plaster mixture;
- starting profile;
- reinforcing corners: they are corners with reinforcing mesh glued to the wings;
- special fasteners for foam plastic( umbrellas) of various lengths.
Let's talk about a set of tools: you should have a drill, drills of various diameters, a nozzle for a drill in the form of a mixer, various containers for building mixes, a spatula or other device to apply plaster, level, stapler, tape measure and brush. In addition, get a metal grater and a construction knife.
The process of mounting foam on the walls of
Before you begin installation of EPS boards , you must carefully prepare a heat-insulated surface. First of all, the wall is cleared of stains and fungal deposits. Further, the surface is carefully leveled, all cracks and cracks are embedded. Only after this you can proceed to the primer.
Once the primer has completely dried, the fastening of the starting profiles is made. Their task is not only to eliminate the slipping of the foam, but also to level the basement part in accordance with the level. Mount the starting profile with dowels. If the walls of the house are made of wood, then you can do it with regular self-tapping screws.
The next stage of work is sticking foam on the wall surface. Pay attention to the fact that the thickness of the foam for wall insulation should be at least 5 cm. This will make it possible to effectively heat the room, and it is much more convenient to work with such plates.
In order to ensure that in the future you do not encounter problems with the removal of slabs from the surface of the walls, during the installation you need to use the right amount of adhesive. It should be applied not only to the foam itself, but also to the surface where the sheet will be glued. All seams are also carefully spread with glue. Mount the plates from the bottom.
After the whole surface is pasted with foam, you need to let it stand for 3-4 days. This will allow the glue to dry completely. Only after this, the plates are fastened with special dowels, which are called "fungus".On one sheet, as a rule, there are 4-5 such fastenings. After this, a layer of plaster is applied, into which the reinforcing mesh is heated. Angles are installed at all angles.
After complete drying of the plaster, you can start decorating. As it may be putty with subsequent painting. Recently, plastering Barkadeh has become very relevant. In more detail, the entire process can be seen on the video about the insulation of walls with foam plastic.
