About Tremco

It was 1928 when William Treuhaft opened his small roofing materials manufacturing plant in Cleveland, Ohio. The company was called Tremco Incorporated. Today Tremco is an RPM International Inc. affiliate company employing over 2,000 people.

Tremco consists of operating divisions specializing in the manufacture and sale of roofing materials and services, construction sealants, glazing and gaskets, waterproofing systems, air barrier and fire stopping systems and a host of custom-designed products, programs and services dedicated to the worldwide construction and maintenance and repair industries. We are committed to helping our customers develop and maintain high performance buildings that operate with the lowest possible life-cycle costs.

As window designs become more complicated and performance standards increase, Tremco glazing materials seal and support the glass, while ensuring occupant comfort.


TremGlaze in-plant polyurethane sealant provides residential window manufactures with unique performance characteristics, including compatibility to self-cleaning glass and easy cleanup.


TremGlaze in-plant silicones offer superior performance for residential window glazing requirements, providing unmatched UV and weathering resistance, exceptional adhesion and long-term durability.
