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.
