StoGuard air barrier helps to construct an airtight building envelope, minimizing the risk of moisture problems - decay, corrosion, loss of insulation value, mold growth and indoor air quality (IAQ) - problems that can occur because of air leakage and condensation. And because StoGuard is fluid applied and structural, it won't rip or tear from the structure.

Moisture barriers in walls protect against the transfer of incidental water into the building. They shield moisture-sensitive components, such as wood or gypsum-based sheathings, during construction and in the event of a breach in the outer wall covering, such as a crack in stucco. StoGuard is a moisture barrier that keeps damaging liquid water from penetrating and saturating the sheathing.
