Composite Technologies Corporation Boone, Iowa   Founded in 1980, Composite Technologies Corporation has been manufacturing and distributing the THERMOMASS Building Insulation System for almost 25 years.   TCA Member Since: 1987

At the heart of the THERMOMASS system is a patented continuous fiber composite connector, which is used to structurally tie two layers of concrete together through predrilled, prefabricated, extruded Dow brand insulation products.

The non-conductive, chemically resistant, fiber composite connector allows the creation of an uninterrupted envelope of insulation throughout the exterior walls of the building. This creates a highly energy efficient building system that is virtually maintenance-free and has the ability to not only resist mold, but stand up to fire, earthquakes, hurricanes and tornadoes as well.

For over 20 years, THERMOMASS has been the industry leading system for concrete sandwich wall construction. Extensive testing, research and development of innovative technologies keeps CTC at the forefront. With a track record of over 100 million square feet of sandwich walls in the US and around the world in use today, we have more experience than all other building insulation systems combined.

"Changing the way the world builds" is not just our slogan, it is the way we do business.
