Air Barrier Membrane

Ensures Energy Efficiency

file

An air barrier is a component within the building envelope with the purpose of controlling air flow between the exterior of the building and the interior environment. Air loss occurs through penetrations, seams and transitions in wall assemblies. When installed correctly, the air barrier greatly contributes to the energy efficiency of a building. According to the U.S Department of Energy, 40% of energy consumption can be attributed to buildings and 40% of the energy loss in building operations is attributed to the building envelope. The building industry recognizes that air barriers are fundamental and necessary to maintain the airtight integrity of the entire building.
