Thermaround™ Is Our Round Solution In Outdoor Duct Applications

The HVAC Industry does not exist on rectangular alone. For applications that require a round or spiral solution for rooftop ductwork, we've developed a pre-insulated solution that offers the same great benefits of Thermaduct with a new, efficient shape. Strong draw band connections allow this round solution to install fast and easy. Our patent pending process allows for a continuous cladded surface with as little as one solvent welded seam!

Offering the same great vinyl cladded protection as rectangular Thermaduct, Thermaround is an excellent solution for the outdoor elements. This high R-value system offers an R-12 insulated value and extremely low air leakage. Thermaround uses same UV stable 1000 micron vinyl cladding for a durable solution that will naturally shed water. In the interior, air passes over a smooth aluminum surface free from loose fibers to give your building better IAQ performance.
