One of the most-cost effective solutions for protecting building envelopes from weather, moisture and air infiltration – the liquid-applied Wall Guardian FW-100A fibered-acrylic air barrier -- will be demonstrated by Kemper System America Inc. at RCI 2018 in Houston, March 22-27.

The half-hour presentation is scheduled for March 25th at 10:15 a.m. in the RCI demo area.

It will include an overview of the history and variety of air barrier systems, as well as a step-by-step demonstration of how to apply the Wall Guardian system. Proven in the field for nearly a decade, the air barrier is designed to resist air and water infiltration, saving energy, and preventing moisture build-up that can lead to mildew and mold.

Performance and Value
Wall Guardian FW-100A air barrier assembly 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. And it exceeds 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.

Presenting for Kemper System will be James Arnold, RRO, PE, Director of Product Development, assisted by Chris Johnston, Technical Services Representative. Arnold has over 30 years of experience in the planning, design, specification and construction of building and public works projects across the U.S. He holds a bachelor’s of Civil Engineering and a Master of Business Administration from the University of Illinois.
