The Kingspan KoolDuct System

The Kingspan KoolDuct System header

Pre-insulated rectangular HVAC ductwork

This cutting edge system comprises premium performance Kingspan KoolDuct panels, fabrication methods, coupling systems, a fabrication training program and a complete line of accessories to produce pre–insulated rectangular HVAC phenolic ductwork that can easily achieve SMACNA air-leakage Class 3.

Kingspan Insulation offers a complete product line providing all materials, tools and accessories necessary for the effective fabrication of phenolic ductwork from The Kingspan KoolDuct System. Kingspan Insulation also provides The Kingspan KoolDuct System Training Course, which is administered through appointed Kingspan KoolDuct System Delivery Partners and selected ITI training facilities.

The fiber-free insulation core of Kingspan KoolDuct panels (the duct wall material) minimizes the risk of loose fibers entering the airstream through the ductwork. This can provide better indoor air quality (IAQ) for building occupants compared with other insulants, which can produce loose fibers when in direct contact with the airstream. Kingspan KoolDuct panels are available in 7/8” and 1 3/16” thicknesses with installed and out of package R-values of R-6.0 and R-8.0 (respectively).
