The acrylic air barrier resists air and water infiltration, saving energy and preventing moisture build-up.

Kemper System America Inc. 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 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.

The engineered system is designed to resist air and water infiltration, saving energy and preventing moisture build-up that can lead to mildew and mold. Compared to house wraps and mechanically-fastened weather barriers, Wall Guardian FW-100A can be applied to building material surfaces with a sprayer, roller or brush.

The liquid-applied air barrier offers unified substrate protection, even on curved or other unconventionally shaped walls. The water-based coating is a low VOC product and meets LEED intent at 25 percent recycled content. The applied coating is also Class A fire rated.

In addition to Wall Guardian FW-100A, Kemper System also offers related air barrier component products through its STS Coatings line acquired in 2016. These include GreatSeal LT-100 polyether Liquid Tape for board-to-board joints, windows, doors, masonry, roof flashings, etc., and UT-40 Universal Tape for sealing cracks, transitions, penetrations and seams in exterior substrate and insulation board.

For over 60 years, Kemper System has been a leader in cold liquid-applied, reinforced roofing and waterproofing, having invented the technology. The company offers a full range of Building Envelope solutions to protect against weather, preserve the integrity of surfaces, and enhance the comfort and value of buildings. This encompasses Wall Guardian fibered acrylic air barrier, Roof Guardian Technologies elastomer-based roof coatings, and HeatBloc-ULTRATM radiant heat barrier.
