The National Air Barrier Association (NABA) began in 1995 as a way to address the issue of the air barrier industry. Canada Mortgage and Housing Corporation (CMHC) estimated that approximately $500 million dollars a year was being spent on premature building failures. A major cause of the problems was improper air barrier systems.
Today, NABA continues to gain momentum as it works with contractors, manufacturers, architects, engineers, consultants, and building owners, to increase the skill level and professionalism in the air barrier industry across Canada. NABA is actively pursuing the expansion of the program across Canada and is currently working on setting up contractors in British Columbia, Alberta, Saskatchewan, Ontario and the maritime provinces.
