Local 34: A legacy of skilled craftsmanship and advocacy for Mechanical Insulation workers.

Founded in 1913, Local 34 of the International Association of Heat and Frost Insulators and Allied Workers has been a pillar for mechanical insulation professionals across Minnesota, Western Wisconsin, and South Dakota. What began as a modest group of 17 charter members has since grown into a thriving community of over 500 skilled members, united by a commitment to fair wages, benefits, safe working conditions, and professional growth.

A Union born from the steam power revolution

The roots of the Heat and Frost Insulators Union lie in the steam power revolution, which transformed energy in both commercial and residential settings. With new boiler systems came the need for mechanical insulation to maximize energy efficiency. Skilled insulation mechanics were essential to the new industry, yet they lacked the union support necessary for fair treatment and safe working conditions. The Heat and Frost Union emerged to advocate for their rights, and Local 34 has continued this mission with a steadfast commitment to its members' well-being.

Meeting today's energy challenges with mechanical insulation

Just as the first union members responded to the demands of steam energy, today's members deliver mechanical insulation solutions that support a radically different energy landscape. Local 34 members play a crucial role in advancing green initiatives, including net-zero energy buildings and retrofit projects that extend the life and efficiency of aging infrastructure. Through skilled application of modern insulation methods, our union members contribute directly to energy conservation efforts that are essential in today's marketplace.

Strengthening the trade through apprenticeship and education

Local 34 does not just unite members- it trains the next generation of insulation experts. Our apprenticeship program pairs seasoned insulators with newcomers, passing down essential skills honed through years of hands-on experience. This mentorship ensures that our members are among the best-trained in the Minnesota/Twin Cities, Wester Wisconsin, and South Dakota areas, ready to meet the high demand for their specialized expertise.

Advocacy and outreach for the mechanical insulation industry

Beyond member support, the Heat and Frost Insulators Union has launched an extensive outreach campaign to educated on the overlooked energy-saving potential of mechanical insulation. through rigorous data analysis and public education efforts, the union has built awareness and job opportunities in this field, positioning mechanical insulation as a key solution in the movement toward energy efficiency.

Local 34 in more than a union- It is a legacy of craftsmanship, advocacy, and progress in energy conservation. With our members at the forefront, we are creating a future where mechanical insulation plays a vital role in sustainable energy solutions.
