What is fluid applied air barrier?
CCW fluid-applied air and vapor barriers are rubberized-asphalt membranes applied by spray or roller. They provide a continuous air/vapor barrier in above-grade wall assemblies and are ideal for use on CMU walls with imbedded masonry ties and similar applications where detailing with sheet membrane is difficult.Click to see full answer.

They provide a continuous air/vapor barrier in above-grade wall assemblies and are ideal for use on CMU walls with imbedded masonry ties and similar applications where detailing with sheet membrane is difficult.Click to see full answer. Similarly, what is the purpose of an air barrier?Air barriers are systems of materials designed and constructed to control airflow between a conditioned space and an unconditioned space. The air barrier system is the primary air enclosure boundary that separates indoor (conditioned) air and outdoor (unconditioned) air.Also, what is vapor permeable air barrier? Vapor Permeable Air Barriers This type of air barrier is designed to allow moisture vapor to pass through the membrane, promoting diffusion. Permeable air barriers are either sheet membranes or fluid-applied, and offer varying rates of permeability. Subsequently, one may also ask, what is an air barrier membrane? Air barriers control air leakage into and out of the building envelope. Air barrier products may take several forms: Mechanically-attached membranes, also known as housewraps, usually a polyethylene-fiber or spun-bonded polyolefin, such as Tyvek is a generally accepted moisture barrier and an air barrier (ASTM E2178).Is Tyvek a vapor barrier?No, DuPont™ Tyvek® is not a vapor barrier. It is made with unique material science to keep air and bulk water out while allowing moisture vapor inside walls to escape.
