CLEVELAND, Ohio—Building-envelope supplier Garland Co. has rolled out a line of permeable air and water barriers designed to provide a "flexible blanket" that controls air movement through the building envelope.

Aero-Perm WB is a fluid-applied, water-based barrier that allows moisture vapors to pass through porous building materials, reducing the chance of mold growth in the wall assembly.

The product is designed to produce a "tough, flexible" membrane that controls air flow while accommodating building movement, according to Garland.

Testing showed air leakage rates below detectable limits, and the system can also be used as an air-, vapor- and water-control layer in rainscreen assemblies, the company says.

Aero-Perm SA is a pre-fabricated, self-adhering air and water barrier membrane engineered for vertical applications where the membrane is protected from long-term ultra-violet exposure. Aero-Perm SA will adhere to metal, concrete and masonry, OSB, plywood and exterior gypsum boards, Garland says.
