The paper presents numerical simulation results of the window block thickness influence of those installed in the outer wall structures on distributing the temperature fields and the magnitude of heat losses through window jambs of outer enclosing structures. When installing the window unit in the outer wall, without additional insulation of the window jambs, heat losses through them constitute a significant fraction of the total heat losses. Under certain conditions, the window block is placed in the area of lower temperatures. The simulation task is realized through external enclosing structures using a computer program. The calculations specified such parameters as: the temperature of the internal and external air, the thermal conductivity factors of the enclosures, the densities of the materials used, as well as the heat transfer factors from the internal and external surfaces of the enclosing structures. According to the results of calculations, it was found that with an increase in the thickness of the window casing, the temperature of the internal jamb near the window block increases, which favorably affects sanitary and hygienic conditions. This reduces heat loss through the window jambs. Based on the obtained data, heat flows through the surface of the wall and side window jambs at different thickness of the window block were determined. Based on results of the simulation, it was found that the use of narrow window casing leads to a significant increase in thermal losses through enclosing structures and an increase in the share of losses through window jambs.
