WEST SENECA, N.Y. – Kemper System America, Inc. now offers Wall Guardian® FW-100A, a liquid-applied fibered acrylic air barrier that also acts as a water/weather barrier and vapor retarder. Evaluated by the Air Barrier Association of America (ABAA), it delivers superior air barrier performance – and value.
Wall Guardian FW-100A exceeds ASTM E2357 (Standard Test Method for Determining Air Leakage of Air Barrier Assemblies) with an air leakage rate of just 0.0004 cfm/ft2 @ 1.57 psf – 100 times better than the test requirement. Notably, the liquid-applied air barrier exceeded the standard in a single coat at 40 mils wet film thickness (40 sq. ft. per gallon). This makes it one of the lowest installed-cost air barrier systems in the U.S.
