air barrier vs vapour barrier




What are the reasons for the presence of water on a building?
If warm ambient air with a high water vapor content reaches a cold wall, the air cools in this region and consequently cannot store as much water vapor. The excess moisture must be added to the environment

do buildings have to breathe?

solar factor
Guarantees the degree of solar protection; it is the fraction of radiation that falls on a hole that is not blocked.
