Air barriers are permeable or impermeable membranes that keeps moisture out of the building envelope.
The system consists of fluid applied or sheet applied membranes with details around doors and openings that create an impermeable or permeable air barrier.
The air barrier system is the primary air enclosure boundary that separates indoor (conditioned) air and outdoor (unconditioned) air. We use top of the line products to eliminate air and water penetration of the building envelope in conditions ranging from everyday weather to the drenching rains and winds of a hurricane. Air barrier systems keep outside air out of the building enclosure or inside air out of the building enclosure depending on climate or configuration. Sometimes, air barrier systems do both.
American River Caulking is certified to apply several vapor permeable air barriers to prevent such occurrences. While fully resistant to moisture in a liquid state, these products allow moisture in a vapor state to pass freely through the membrane. The products are typically a single component, fluid-applied option that is easy to install and would be applied in lieu of the current code dictating asphalt impregnated building paper. We use “green” environmentally responsible air barrier system.
The air barrier project pictured above was completed for The Meadows of Napa Valley. This air barrier was installed inside the indoor pool building ceiling and walls to keep the chlorine gasses from eroding the building. One of our larger projects, the Bayshore Elementary School located in Daly City, CA, required an air barrier approximately 35,000 square feet.
