Warming the house is an extremely important task. Correctly picking up the material, you can significantly reduce the cost of heating. In recent years, mineral wool has been used for this purpose most often. However, progress does not stand still, and manufacturers are developing more and more new materials. The most interesting of all, invented in recent years, can be considered a foam, the characteristics of which allow it to be used to insulate buildings with greater success than the same mineral wool.
This material is made of polystyreneby extrusion. Depending on the density, the marked 31, 31C, 35C, 35 and 45 penoplexes are distinguished. The technical characteristics of all these types are somewhat different. However, almost all of them can be used to build an apartment house. The most popular can be considered a foam pen marked with a figure of 35. It optimally combines excellent performance and reasonable cost. The standard width of the plates is 60 cm, length - 120.
This heater not only perfectly preservesheat, but, as already mentioned above, perfectly resists the effects of moisture. Their excellent performance characteristics of the board are preserved even with a very long direct contact with water at any temperature. The highest degree of mechanical strength is another interesting property of a material such as foam foam.
If we talk about thermal conductivity itself,then the most excellent performance characteristics in this respect became possible due to the fact that this material has a cellular structure. The degree of thermal conductivity in this case directly depends on the density of the foam foam material. The characteristics in this plan do not practically change with the increase in the thickness of the material. This is due to the peculiarities of its structure. The level of thermal conductivity, depending on the density, can thus be 0.025-0.03 W / mK.
