The function of moisture barriers in walls is to protect against the transfer of incidental water into the building. Additionally, they shield moisture sensitive components, such as wood or gypsum-based sheathings, in the event of a breach in the outer wall covering, such as a crack in stucco.

The conventional choice for moisture protection has been asphalt saturated felt or paper. In addition to tearing and mis-lapping during construction, felt or paper might suffer significant performance break down with exposure to weather conditions. StoGuard™ can be left uncovered for up to six months (Sto GoldCoat) or two months (Sto EmeraldCoat) with minimal degrading.

StoGuard™ has the added ability to allow water vapor to pass through yet keep damaging liquid water from penetrating and saturating the sheathing. By applying StoGuard™ as your waterproofing treatment you can have the peace of mind that your walls have minimized risk of damage from water intrusion during or after construction.

Unlike some sheet membranes that do not allow water vapor to diffuse through, the StoGuard™ assembly is water vapor permeable. By allowing for water vapor diffusion, while limiting air infiltration, StoGuard™' is "breathable". As a "breathable" waterproof air barrier, StoGuard™ permits water vapor to diffuse through it. This is important for the drying of the wall, should water accumulate in materials during construction or incidental water leakage occur after construction.
