Continuous air barriers are essential for a building’s energy efficiency, durability and indoor air quality - and are currently required by energy codes. There are several types of air barriers commonly used in the industry, including building wraps, self-adhered, and fluid applied membranes. This course focuses on fluid applied air barriers which have continued to increase in popularity in recent years. The main properties of fluid applied air barrier systems which include wet and cured thickness, vapor permeability, water sensitivity, elongation & recovery, and UV resistance vary over a very broad range and are largely determined by their chemistries and formulations. This presentation will highlight the key differences and performance advantages of new high performance fluid applied air barriers based on their chemistries.
