Material designed to control the movement of air.
Buildings are now being designed with a significant emphasis on the quality of the air/vapor barriers that encapsulate them.
By controlling airflow, the indoor temperatures are able to remain more consistent with the build settings. Along with that, by controlling the moisture/water vapor which can enter a building, a high-quality AUB (air vapor barrier) can increase the “health” of a building and its occupants by lowering the risk of mold and structural deterioration.
