From humble beginnings, TPS has grown to become the largest fabricator of insulated pipe supports North America. TPS is part of a family of companies which includes the 3rd largest union mechanical insulation contracting firm in the Seattle area. We are proud to also have a 4th generation family member as a Union Insulator. Our company has a strong heritage in the mechanical insulation business with 3 generations of family owner/operators with experience dating back to 1942. TPS was founded by a mechanical insulator who saw an opportunity to fabricate his own insulated pipe supports instead of buying them. With the hard work ethic and tenacity he learned in the home and field, he grew the business to now service all of the top insulation distribution companies. Today, TPS is broadening our influence in the mechanical insulation industry by now offering three major types of industrial insulations including Calcium Silicate, Expanded Perlite and Phenolic Foam. Our mission is to seek out the BEST mechanical insulations in the world and bring them to North America’s underserved distinct product markets adding competition where little or none existed with stronger and more cost effective choices.
