What Thermaduct does
Thermaduct is a privately held US manufacturer of pre-insulated phenolic ductwork systems for commercial and industrial HVAC applications, headquartered in Perrysburg, Ohio. The company designs and produces a portfolio of factory-fabricated duct, insulation, and cladding products, including Thermaduct (rectangular outdoor), Thermaround (round outdoor), InspiralR (indoor round), Floval (indoor flat oval), Thermatuff (phenolic panels and duct liner), Thermaduct Architectural Products (metal-clad variants), and the Lineset Portal (insulated rooftop line/pipe/conduit portal). Core technology centers on closed-cell phenolic foam insulation integrated with smooth aluminum interiors and 1000-micron UV-stable vinyl or metal cladding, protected by multiple US patents covering fabrication processes, reinforcement systems, and product designs. Products deliver R-6 through R-24 insulation values, near-zero air leakage, and up to 75% weight reduction versus traditional double-wall metal duct.
The company sells through a channel-led model: a nationwide network of manufacturers' representatives provides localized sales and quoting, while SMACNA contractor fabrication facilities across the United States and Canada handle regional fabrication. Pricing is project-based and quote-driven, with no public price list. Target customers include commercial HVAC contractors, architects, and engineers, with end-market adoption demonstrated in healthcare, pharmaceutical, government, commercial office, education, hospitality, multifamily residential, and industrial facilities. Marketing is content-driven, centered on technical case studies, free online training courses, webinars, submittals, and specification support aimed at the design and contractor ecosystem. The company is roughly 20 years old (founded 2004), employs 11-50 people, does not disclose revenue, and operates without disclosed outside funding or institutional ownership.
