KoolDuct Liner System

KoolDuct insulated liner board has a fiber-free rigid phenolic insulation core with factory-applied aluminum foil facings on both sides. The insulation core is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Product Highlights

  • KoolDuct boards can be used as internal liner insulation in sheet metal air handling ducts for HVAC applications.

  • A fiber–free, rigid insulation core minimizes the risk of loose fibers entering the airstream through the ductwork. 

  • The rigidity of the material allows for easy installation and a tight fit at corners.
