| Title of the article | Water vapor permeability of materials under actual operating conditions |
| Abstract. | This article discusses methods for determining the water vapor permeability of building materials, and indicates the need for testing of materials under actual operating conditions. The article is devoted to the experimental study of water vapor permeability considering wind effects on the surface of the test specimens. Understanding the process of water vapor permeability interconnected with real operating conditions of enclosing structure, will enable proper evaluation and prediction of water vapor permeability of the assembly, which guarantees the preservation of its thermal characteristics and durability. The authors developed an experimental setup that simulates actual operating conditions of a wall structure. A distinctive feature of the method described in the article is that it allows to analyze the kinetics of water vapor permeability considering the movement of air at the surface of the sample. The obtained results of a study of some insulating materials presented in the article talking about the need of scientific development on this issue. |
