Pre-Insulated Ductwork Liner System

KoolDuct® insulation duct liner board has a fiber-free rigid phenolic core with factory-applied aluminum foil vapor barrier facings on both sides. It can be used as an internal liner insulation in sheet metal air handling ducts for HVAC applications.

The rigidity of the material allows for easy installation and a tight fit at corners where non-rigid products risk being overstretched and compressed. The insulation core is manufactured with a blowing agent that has zero ODP and low GWP.
