It is affiliated with the AFL–CIO and the Canadian Labour Congress and the North America's Building Trades Unions. The union was formerly known as the International Association of Heat and Frost Insulators and Asbestos Workers, but the name was changed to reflect a symbolic new direction away from the hazards of exposure to asbestos.
