| Title of the article | Influence of temperature and moist operating conditions of construction materials on their vapor permeability |
| Abstract. | Moisture vapor diffusion process can lead to moistening of the enclosing structure and reduce its thermal characteristics. These processes have been studied for many years, but there is still a number of unexplored issues. One of them – variability of vapor permeability depending on operating conditions, such as humidity and temperature. The researches made in this area only establish dependence of vapor permeability on temperature and moist conditions, however do not give theoretical justification to these dependences and are not put into practice. So in engineering calculations to ensure the protection of the enclosing structure waterlogged vapor permeability coefficient is assumed constant. In article results of pilot research of vapor permeability of materials taking into account temperature and moist conditions of samples are analyzed. It is proved that vapor permeability of construction materials (?) changes depending on humidity, temperature and arrangement of material layers of design. Need of measurement of vapor permeability of construction materials for the broad range of temperature and moist conditions are confirmed. |
