About Thermaduct™


About Us

Thermaduct LLC, headquartered in Perrysburg Ohio, is the pioneer of pre-engineered and pre-insulated outdoor ducting systems. Seeing historic issues with exposed air distribution systems, our engineers have designed and manufactured a pre-insulated outdoor ducting solution.

Providing high R-values and low air leakage, the Thermaduct™ system cuts down on energy costs by eliminating the factors that attribute to energy loss in the outdoor environments. This superior outdoor air distribution system is constructed to the highest fabrication standards by Thermaduct™ trained members of the Sheet Metal Workers International Union.

High quality products from highly skilled workers will ensure your project exceeds the client's expectations with a weather resilient and energy efficient HVAC system.
