Wall Guardian FW-100A air barrier, part of the company’s STS Coatings line, is designed to resist air and water infiltration. Compared to house wraps and mechanically-fastened weather barriers, the fibered acrylic can be quickly applied to building materialsurfaces witha heavy-duty sprayer, roller or brush.
“While Wall Guardian has been in the marketplace for almost 15 years, there are still many specifiers and applicators who are not aware that a high level of performance can be achieved in a liquid-applied air barrier -- or the high potential for cost savings on a project,” said Jim Arnold, PE, RRO, director of product development, Kemper System America, Inc.
The fibered-acrylic coating 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. It exceeded the standard in a single coat at 40 mils wet film thickness (40 sq. ft. per gallon).
The liquid-applied air barrier offers unified substrate protection, even on curved or other unconventionally shaped walls. The water-based coating is a very-low VOC product and exceeds LEED qualifications at 25 percent recycled content.
In addition to Wall Guardian FW-100A, Kemper System also offers related air barrier components through its STS Coatings line. These components include GreatSealLT-100 polyether Liquid Tape for board-to-board joints, windows, doors, masonry, roof flashings, etc., and UT-40 Universal Tape for quickly sealing transitions, penetrations and seams in exterior substrate and insulation board.
