Streszczenie: The solution to the problem of creating efficient porous thermal insulation materials and technologies for their production is inextricably linked to scientific research in the field of energy transfer in the porous structure during the swelling, curing and drying stages, providing the lowest thermal conductivity and density. The above-mentioned properties of materials are determined by the size of their porosity, by the ratio of micro- and macro-abundant materials, and by the properties of inter-porous materials forming a distinctive bearing frame, which in turn is determined by the production technology, type of raw materials and the conditions for their preparation. The problem of heat treatment of wet materials contains the question of the heat and mass inside the body transfer (an internal problem) and in the boundary layer at the interface between phases (an external problem). The amount of removable moisture depends on the degree of each of these processes development. When heated, the moisture content on the surface decreases, and this creates a concentration difference across the body. Therefore, a flow of moisture occurs in the body from the deep layers to the surface towards which the flow of heat is directed.
