Air Barriers are designed to control the unintended movement of air into and out of a building structure.

Air barrier systems provide a complete barrier to air leakage throughout the building structure. The system essentially "wraps" the entire building protecting it from the effects of air leakage. Air leakage can have a detrimental effect on how a building functions and can reduce the life span of a building.

A properly installed air barrier system provides a barrier against both air leakage and the diffusion of air caused by high outside winds, stack and internal building HVAC equipment pressures. It also will allow interior moisture to escape to the outside air, preventing the formation of mold.

Architects and building engineers cannot stress enough the importance of air barriers in commercial building design and construction. Buildings without air barriers will experience major failures in terms of moisture damage and mold caused by condensation, all linked to air leakage.
