Kingspan KoolDuct Non-Fibrous Duct Liner

Kingspan KoolDuct fiber-free, rigid phenolic insulation panels are now available for use as an interior duct liner for HVAC applications. This newly developed, patent-pending method of construction allows for the same panels used in Kingpsan's UL 181 listed system to now be applied to sheet metal ductwork for a fiber free lined duct that does not require adhesives. KoolDuct liner performs better than an insulated duct that uses traditional limp, non-structural insulation that requires glue and pins to keep it in place.

Using KoolDuct to line your metal ductwork will contribute to the strength and performance of your duct by increasing R-values and lowering air leakage. Even more important in today's IAQ goals...KoolDuct applied as a liner resists accumulation that can lead to mold growth in ductwork insulation.

Kingspan KoolDuct Phenolic Duct Liner

Easily Applied in both the Shop or The Field

The rigidity of the KoolDuct phenolic panel allows for easy installation and a tight fit at corners where non-rigid products risk being overstretched and compressed. KoolDuct can be installed into your pre-fab ductwork before it leaves your shop or easily applied in the field with limited tools required. Limited fabrication investment is necessary and you can begin cutting most applications with simply a table saw. KoolDuct is available in 4’ x 13’ panels in a variety of thicknesses that supply different R-values between R-6 and R12.

Kingspan’s installation guidelines are easy to follow for a smooth process that will greatly increase your ductwork’s efficiency.
