Superior Air Distribution

Thermaduct is committed to bringing the very best air distribution technology in the industry to our customers. Unsurpassed performance was our goal: to create duct systems that can not only deliver every cubic foot of air it is fed, but to treat the air with the utmost respect by not exposing it to fibrous or volatile organic chemical latent liners.

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.
