Pro-R Indoor ductwork is your lightweight, durable, and easy-to-install solution for interior projects

Pro-R Indoor provides superior thermal performance and ease of install with the proven KoolDuct system

Pro-R Indoor builds upon the Kingspan KoolDuct system to provide a stronger, pre-assembled, extremely lightweight and high performance solution for all interior insulated ductwork applications. This enhancement of KoolDuct allows the application in higher static pressure projects as well as in environments that require a thermal break.

Regular KoolDuct is also available through our Pro-R Indoor product line which provides a great solution for low static pressure applications. Our indoor phenolic solution offers high R-values up to R-12 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 foam insulation.

Pro-R Indoor weighs about half as much as traditional insulated duct, 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.
