Kingspan Therma™ Duct Insulation is an energy efficient rigid insulation for rectangular, circular and flat oval HVAC ductwork installed outdoors, suitable for both new build and refurbishment projects in the residential, commercial, institutional and industrial sectors.

Insulation located outdoors must be protected with a compatible weatherproof material.

Kingspan Therma™ Duct Insulation comprises a fibre-free rigid polyisocyanurate (PIR) insulation core, faced on both sides with a protective low vapour permeability trilaminate foil.

Insulated duct support inserts:

Load-bearing insulation inserts can be fabricated from standard Kingspan Therma™ Duct Insulation boards for ductwork installed outdoors.

Flat rectangular strips of Kingspan Therma™ Duct Insulation are used on support brackets with rectangular and flat oval ductwork. Curved strips of Therma™ Duct Insulation (crocodile strips) or strips of Kingspan Tarec™pir Pipe insulation are used on support brackets with circular ductwork.
