Thermal Protection of Multi-layer Exterior Walls with an Expanded Polystyrene Core

In the article, the results of the study of temperature and humidity conditions of a multilayered structure in climatic conditions of Southern Siberia are stated. The complex analysis of a heat-shielding of a building is made. The humidity condition of multilayered external walls is studied. The basic construction units with the purpose of revealing of cold bridges are researched. Fields of temperature deformations of external walls are received. Unsuccessful experience of application of 3D-panels is shown, and ways of their elimination from the point of view of increase of a heat-shielding are offered. Methods of research represent modeling by means of ELCUT and SCAD Office software packages. Recommendations for the design of construction units of a building using 3D-panel technology are proposed in accordance with the requirements of not only normative documents, but also from the perspective of a comfortable thermal environment of the rooms.
