THERMAROUND™ OUTDOOR DUCT SYSTEM – ROUND SPIRAL DUCT ALTERNATIVE
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 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.

Factory Laminated & Virtually Seamless Vinyl Cladding
With a continuous cladded surface, Thermaround virtually eliminates common areas of water intrusion. Our 1000 micron, UV stable vinyl cladding is factory applied to our closed cell insulation with a full lamination process for a permanent bond. This strong barrier keeps outdoor elements out and conditioned air in to ensure high efficiency air distribution.
Duct sections are designed to have as few as one solvent welded seam for an uncompromising protective surface that requires no field installation of cladding.
Outdoor Efficiency - Designed with Architects in Mind
Whether your application is looking for “cool roof” efficiency or just “cool” colors, Thermaround is now available with an optional Kynar finish metal exterior. This opens up more opportunities for architectural application where the look of your ductwork play a key role in building design, while still allowing for the pre-insulated quality of Thermaround.
