Thermaround was introduced in 2019, designing the best parts of our Thermaduct system to have a more efficient shape for outdoor dynamic loads. As a non-metal alternative to spiral or round rooftop ductwork, Thermaround is a pre-insulated solution that offers your duct, insulation and cladding all in one product. Strong flanged connections allow this round solution to install fast and easy. Our patented process allows for a continuous cladded surface with as few as one solvent welded seam!

With a standard 1000 micron vinyl cladding cladding that offers the same weather resistant protection as rectangular Thermaduct, Thermaround is an excellent lightweight solution for the outdoor elements. This high R-value system offers an installed R-12 insulated value and extremely low air leakage. Thermaround offers multiple cladding options with both our vinyl or architectural metal for a durable solution that will naturally shed water. In the interior, air passes over a smooth aluminum phenolic surface free from loose fibers to give your building better IAQ performance.
