Generalized theoretical model of thermal protection of residential buildings using external frame filling
The causes of condensation inside the frame fillings depending on the dynamics of the temperature change have been researched. In terms of the diffusion process the rational sequence of layers of the external enclosure has been established. The maximum preferences should be given to the external thermal insulation, since a thermal storage capacity of a wall increases and heat protective characteristics improve. When using other schemas (inside the walls, on the inner side of the wall), condensation can occur, preventing the equilibrium state of the external enclosure. Windows refer to the external enclosure, through which significant (up to 35%) heat losses occur. Therefore, from the point of view of building physics one should pay attention to the correct window installer technology in new and the replacement of old ones in the reconstructed buildings; that, according to the authors of the article can provide substantial savings in heat and in some cases without additional heat insulation of walls. Algorithm of thermal protection represents a logical sequence of steps in the design and implementation of external enclosures of buildings.
