An energy-efficient rigid insulation for rectangular, circular and flat oval HVAC ductwork.
Suitable for use on rectangular, circular and flat oval ductwork in HVAC or building services applications.
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. Comprised of a fibre-free rigid phenolic insulation core externally faced with an aluminium vapour barrier foil and internally with a glass tissue based facing.
Insulated duct support inserts:
Load-bearing insulation inserts can be fabricated from standard boards. Flat, rectangular strips are used on support brackets with rectangular and flat oval ductwork. Curved strips (crocodile strips) or strips of Kingspan Kooltherm Pipe insulation are used on support brackets with circular ductwork.
Features and benefits:
Faced on one side with a low emissivity aluminium vapour barrier foil, and faced on the other side with a glass tissue based facing.
Glass tissue facing
