Construction Roofing Diffusion Membranes: Types and Characteristics, Direction of Scientific Research

In the technological tasks of construction, there are often problems of creating coatings that protect the structures of buildings and structures from wind, moisture and dust, as well as providing them with additional sealing. One of the ways to solve this problem is the use of vapor-permeable diffusion membranes in the construction of multilayer heated roofs. Foreign and domestic industry produces a wide variety of pseudo-diffusion and diffusion roofing materials with various operational thermophysical properties. The main thermal technical characteristics of ventilated frame walls and insulated roofs are: thermal conductivity, air permeability, vapor permeability, resistance to deformation, mechanical strength. In addition, the mandatory conditions for the effective use of such structures is the compatibility of structural elements and the quality of installation work. In this regard, there is a need to conduct a number of theoretical and experimental studies in order to develop scientifically sound methods and recommendations for the construction of ventilated facades and insulated attic rooms. The main objectives of research in this direction are: the study of the use of various diffusion materials in different climatic conditions to save energy; prospects for the use of diffusion membranes as gas separation systems that support indoor microclimate; development of methods for organizing the construction of multilayer ventilated walls and insulated attic rooms.
