Air & Moisture Barriers

The StoGuard® family of air and moisture barrier products serve as the first line of protection against moisture intrusion and air leakage and are featured in all Sto wall systems.

Controlling air leakage through the building envelope is critical to achieving highly energy efficient buildings. Regardless of region or climate, research has shown that air barriers can play a larger role in energy efficiency than increasing insulation thickness. But unlike building wrap barriers that are penetrated by staples and fasteners for their attachment, the StoGuard® System provides seamless control over air and moisture to improve building performance and occupant comfort.
