Forging alliances 

At Insulators Local 34, we aren’t satisfied with training the best mechanical insulation installers in the business. We’re hard at work bringing business to our members. In May 2009, The National Insulation Association and International Association of Heat and Frost Insulators and Allied Workers formed a powerful alliance to generate awareness of mechanical’s insulations many benefits. Our outreach includes a robust campaign that effectively harnesses solid data and powerful financial arguments to target potential industrial and retail clients. So far, that campaign has generated hundreds of jobs and thousands of miles of insulation.
