Air barrier systems help separate the outside environment from the desired interior environment. Ultimately, an air barrier creates seamless continuity and structural integrity that helps eliminate uncontrolled air leakage and allows control over temperature, humidity, moisture and air quality throughout the building. With a properly installed air barrier system, you can improve a building’s performance and reduce heating and cooling costs by as much as 36%, according to the US Department of Energy.
Air Barrier Types
The selection and placement of air barrier products is based on several factors, including exterior climate, direction of airflow and structural design. Air barrier products may take several forms:
- Mechanically-attached membranes, also known as housewraps, usually a polyethylene-fiber or spun-bonded polyolefin is a generally accepted moisture barrier and an air barrier.
- Self-adhered membranes, which are typically also a water resistant barrier and a vapor barrier
- Fluid-applied membranes, such as heavy-bodied paints or coatings including polymeric based and asphaltic based materials
- Closed-cell medium density spray-applied polyurethane foam, which typically provides insulation as well
- Some open-cell spray-applied polyurethane foam that are of high density
- Boardstock, which includes 12 mm plywood or OSB, 25 mm extruded polystyrene, etc.
