Air Barrier
Air barriers are required in building walls, regardless of region or climate. StoGuard’s continuous, fluid-applied waterproof air barrier membrane bonds directly to sheathing to resist air and water penetration.

Moisture Barrier
StoGuard is a moisture barrier that protects against the damaging effects of incidental water that can enter and damage wall components.

Vapor Diffusion
Sto’s system aids in preventing water vapor from getting trapped inside walls.
