Abstract
Today for a construction combination of availability, environmental friendliness, ease of installation and thermal conductivity of heat insulators are very important. In this article that kind of materials are considered. The main function of the heat-insulating material is to prevent heat loss from the insulated space. The transfer of heat is caused by the movement of molecules, which can not be stopped completely, but can be reduced. This property was taken as the basis for the production of heatinsulating materials, which are air packed in various ways: in pores, cells, capsules.
