| Abstract | Air barrier systems (ABS) are specified in Canadian codes to minimize the infiltration and exfiltration of air through the building envelope in order to control the risk of condensation. However, since the publication of the Energy Code of Canada in 2014, more attention has been drawn to the importance of an air barrier system to control the loss of energy. Recently, the Canadian Construction Material Centre (CCMC) developed performance criteria for liquid-applied ABS, including installation, barrier, and durability criteria. The CCMC is a recognized body that provides guidance to building officials with respect to the National Building Code of Canada (NBC) and the evaluation and testing of innovative products as alternative solutions meeting the requirements of the NBC. The performance criteria for an ABS will be of interest to air barrier material and air barrier system providers, architects, industry consultants, and contractors. |
