The linear coefficients of heat transfer of the nodes of the window block to the external walls are analyzed, the values of which are recommended by the existing regulatory framework. It is noticed that the existing design of the junction is not energy efficient enough. An improved method of constructing the node of the window block to the outer wall to increase the thermal resistance, which is protected by a utility model patent, is proposed. Reduction of heat loss is achieved by installing a layer of aerogel insulation at the junction of the wall to the window unit, on top of which is applied thermal insulation plaster. Based on the simulation of the window unit adjacency unit to the outer wall in the DAMWERK software package, the energy efficiency analysis of the proposed design of the window unit adjacency unit to the outer wall as a "cold bridge" was performed.
