Thermaduct is a high-efficiency, pre insulated ductwork system engineered for both interior and exterior applications - combining the duct, insulation and weather protection into one lightweight assembly.

Designed to improve energy performance with higher R-values and very low air leakage, Thermaduct helps speed installation by eliminating the need for separate duct wrap or field applied insulation. Many Thermaduct systems are UL 181 listed and are supported by a 10-year limited warranty.

As the Greater Philadelphia fabricator of Thermaduct, our shop can support projects with accurate fabrication, reliable lead times, and consistent quality.
