This article considers the features of the use of monolithic foam concrete as a heat-insulating layer in the building enveloping structures of buildings operated under intermitt ent heating conditions. To assess the eff ectiveness of the use of monolithic foam concrete in building enveloping structures, a thermal engineering calculation of the outer wall, insulated with the use of monolithic foam concrete, was carried out. Based on the calculations carried out by the authors, graphs of the dependence of the heating time of multilayered enclosing structures on the thickness of the heat-insulating layer and the reduced resistance to heat transfer of the structure were obtained. The optimum range of thicknesses and densities of monolithic foam concrete for thermal insulation of external walls of buildings, operated in conditions of intermitt ent heating, is off ered. This calculation also showed that the use of foam concrete as a heater from the inside of the outer wall can reduce the load on the foundation of the building.
