4. Conclusions The article investigates the issues of improving the energy efficiency of buildings by developing new porous insulation structures. In the article there is a study of the technique conducted on the modern design of thermal protection. A design consisting of an elastic ceramic fabric and a thin basalt sheet was proposed. The geometric characteristics of the porous structure and the thermal permeability of porous insulating materials were determined in the article. A calculation model for the transfer of thermal energy through porous construction was developed, which made it possible to reduce the complexity of work in determining the effective thermal conductivity of porous structures. The new dependencies are based on the theory of thermal energy transfer by fluids and allow to calculate the amount of energy passing through the porous constructions, taking into account the operating conditions, only by defining two semi-empirical coefficients previously. Thus, the product of the constants of the integration of the energy transfer equation by fluids and the geometric characteristics of the porous structure and the thermal permeability of fourteen porous materials used as elements of thermal protection of buildings were found.
