Physical Analysis of Water Vapour in Function Gap

Abstract:

The article is focused on the physical analysis of water vapour in functional gap. The creation of condensate (respectively frost) in the cavity is not treated by norms or regulations. The level of importance of condensation is different depending on the material basis. In case of wooden window constructions, the surface treatment is degraded and their technical-physical features. The primary reason of condensation is transfer of humidity through the cavity between the window casement and its frame at reaching the temperature of dew point. The transfer causes: the difference of air pressures (which drifts vapour) – infiltration and exfiltration and diffusion of vapour (different saturation of vapour in external and internal air, diffusion flux is, under certain circumstances, able to flow in a different direction than airflow).
