KoolDuct, utilized in our Pro-R Indoor product line, is your lightweight and easy-to-install solution for interior ductwork

The Kingspan KoolDuct system, part of our Pro-R Indoor ductwork offering, provides superior thermal performance & ease of install.

The Kingspan KoolDuct system is a pre-insulated, closed-cell phenolic, complete HVAC ductwork system that offers a revolutionary new way of completing ductwork projects. Traditionally, HVAC ductwork is fabricated from galvanized sheet metal, which is installed and then insulated afterwards. KoolDuct on the other hand is both the ductwork and the insulation, all in one. Its pre-insulated and pre-assembled construction eliminates the need for an insulation contractor while also saving space (no need to leave extra room to wrap the ductwork) and reducing labor costs due to its lightweight and innovative design.

Kingspan KoolDuct's UL 181 Listed status

Our Pro-R Indoor product includes the KoolDuct system but also takes the product a step further by providing a reinforced version for applications with higher static pressure or for applications needing a thermal break and TDC connections (standard KoolDuct utilizes tiger clip or 4 bolt connections). With KoolDuct, our Pro-R indoor phenolic solution offers the highest R-values in the industry ranging from R-6 to R-24 and near-zero leakage rates. Pro-R Indoor is contractor friendly and built to SMACNA Standards. Providing a long-life duct solution, Pro-R greatly reduces air leakage, provides superior thermal performance and unmatched ease-of-install with an efficient closed-cell phenolic insulation.

Pro-R Indoor weighs up to 72% less vs. traditional insulated ductwork fabricated from galvanized sheet metal and mineral fiber insulation, which in return saves on labor cost and makes it the perfect solution for tight spaces.

If you’re looking for an easy-to-install, efficient, pre-insulated ductwork solution for your next project, look to Pro-R.
