An energy efficient rigid insulation for rectangular, circular and flat oval HVAC ductwork, suitable for new build and refurbishment projects in the residential, commercial, institutional and industrial sectors.
Kingspan Kooltherm Duct Insulation is an energy efficient rigid insulation for rectangular, circular and flat oval HVAC ductwork, suitable for both new build and refurbishment projects in the residential, commercial, institutional and industrial sectors.
Comprised of a fibre-free rigid phenolic insulation core, faced on one side (external face) with an aluminium vapour barrier foil, and faced on the other side (internal face) with a glass tissue based facing.
Insulated duct support inserts:
Load-bearing insulation inserts can be fabricated from standard Kingspan Kooltherm Duct Insulation boards.
Flat rectangular strips of Kingspan KoolthermDuct Insulation are used on support brackets with rectangular and flat oval ductwork. Curved strips of Kingspan KoolthermDuct Insulation (crocodile strips) or strips of Kingspan KoolthermPipe Insulation are used on support brackets with circular ductwork.
FM approved to Factory Mutual (FM) Research Standard 4924 when manufactured and installed in accordance with the conditions defined by the approval. It is a low fire hazard product acceptable in itself, without requiring automatic sprinkler protection.
