Who We Represent
Today’s union insulator is skilled in the installation of mechanical insulation, fire stopping, asbestos and lead mitigation or abatement, sound attenuation and specialty fabrications required in custom mechanical insulation installations for commercial, industrial, medical, bio-technical, governmental and educational facilities among other customer types. This work is installed by our professional mechanical insulators who achieved journeyman status in the union through a multi-year classroom and 1,600-hour per year on-the-job training program second to none in North America.
The International Association of Heat and Frost Insulators and Allied Workers has persevered since 1903, a testament to our founders’ commitment to the dignity, skills and well-being of our membership. For more than 120 years, our union has endured, through good times and bad, in peacetime and at war, through economic depression and prosperity, in favor and out of favor with governments and politicians. Through it all, we not only have survived; we have flourished.
