As a result of theoretical and experimental experiments conducted in this study, the specifics of the temperature field in the heat-insulated parts of the outer wall of a hidden metal frame of a residential building built of cement sandwich panels in dry hot conditions of Uzbekistan were identified.

In this research work, practical experiments were conducted to use energy-saving materials in the design of residential buildings being built in a new type in the Republic, as well as the use of materials that support energy conservation in buildings, are rough and accessible to the public, as well as in the construction of houses using building materials that correspond to the use of such building materials for external enclosing structures, it is possible to increase the energy efficiency of buildings.Keywords:external fencing structure, thermal protection, energy efficiency, material, need, boundary, project, economy
