No one should particularly campaign on the acquisition of energy -saving technologies all the more in the field of housing construction. Energy rates in constantly force us to take care of the savings of energy. Along with the traditional methods of energy saving, such as a decrease in heat loss thanks to new windows and doors.
The windows differ from the doors in that they constantly emit energy, even if these are double -glazed windows. So we will talk about reducing energy losses from the windows next time, and now we will concentrate on heat loss due to walls of buildings.
It is clear that the walls made of stone are highly thermal conductivity are quite high. How to reduce heat loss? From the school desk, we know that the most optimal heat insulator after a vacuum is of course air, in this case, porous materials, for example, mineral wool or foam, which are a layered structure, are amazing heat guardians.
Now let’s try to understand which of these 2 materials will be better to protect heat and why? To answer this question, you need to know that the mineral wool is such a fibrous form of silicon oxide, while it itself has a high indicator of thermal conductivity, but polystyrene is such a porous formation of foamopoliegate, the one that has a fairly low thermal conductivity.
Thus, if during the construction of walls the polyurethane or polystyrene foam is used, then in this case the walls are a Sentwitch, the filling of which is a foam. Foam can keep warm enough well, but it has low mechanical strength, and it does not hold its high temperature quite poorly.
Now we conclude: where there are no mechanical loads and thermal loading cannot appear, foam can be used, but it holds heat many times better, unlike mineral wool. Otherwise, you need to opt for fibrous silicon oxide.
