Use KoolDuct as a Duct Liner for your Sheet Metal ductwork

A New Alternative to Fiberglass and Elastomeric Liners

The Kingspan KoolDuct System is now available as an interior liner for sheet metal ductwork. Newly developed methods for applying this patent pending construction process allow for KoolDuct's rigid phenolic panels from the UL 181 listed system to now be used to traditional metal ductwork. This fiber free insulation liner does not require adhesives and offers newfound strength to your ductwork. Using KoolDuct in place of a traditional limp, non-structural liner will give strength, performance, increased R-values and lower air leakage rates. Meet your IAQ goals with a duct insulation liner that resists mold growth.
