Featured Projects:

Industrial Facility - InspiralR & Floval

Thermaduct’s InspiralR and Floval systems were installed in an industrial facility in Missouri. This application used 7,700 square feet of pre-insulated R-6 round and flat oval ductwork with sizes up to 82 x 22 inches. This provided the installation a large reduction in weight over the entirety of the building.

Outdoor Ductwork with Vinyl Cladding

Texas University Application - Thermaduct

Steady lead times were needed at this university application to meet deadlines without depending on multiple vendors and variable prices. When other options were needed for the 32,000 square foot system, R-12 Thermaduct was chosen because of both a material and installation cost savings over the course of the project.

Weatherproof Ductwork Exterior Applications

Superior Air Distribution

Our family of innovative, pre-insulated duct systems that support just about any application. All of our products use the highest quality closed cell phenolic to give customers the best insulation value without taking up valuable interior or exterior space. By ordering a Thermaduct product, you can be confident that you’ll receive a lightweight, low air leakage and high R-value product that is backed by a 10 year limited warranty.

We believe that high efficiency should not stop at your HVAC equipment, but rather should encompass the entire management of energy through intelligent controls and efficient air distribution. We offer a more efficient air distribution system, promoted by employing fiber free Kingspan KoolDuct. With higher thermal values and lower air leakage than traditional air distribution systems, you'll notice a difference with Thermaduct ductwork products for your indoor and outdoor applications.

With all of our pre-insulated systems, air passes over the smooth aluminum surface of Kingspan KoolDuct’s closed cell phenolic panels, with a variety of additional lining options should an application require it.
