Local 25

We proudly utilize industry-trained union insulators from Local 25. The International Association of Heat and Frost Insulators and Allied Workers is a trade union in the United States and Canada.

Its history is long and deep, dating back to 1903. Workers in this union are highly trained, with apprenticeships available in companies like Rival Insulation, where they learn the trade with the attention-to-detail, hands-on approach dedicated companies are known for. All workforce training includes OSHA 10-hour and 30-hour safety training courses, 3E energy audits, CPR and first aid training, a professional code of conduct program, and more.

Mechanical Insulation is one area of expertise within the Local 25 trade union. Insulating and jacketing mechanical systems provides many benefits including reduced energy costs, enhanced performance of mechanical systems, reduced emissions, condensation prevention and many more benefits.

Our workers not only install mechanical insulation on commercial and industrial sites, but also maintain these systems throughout their life.
