Therma Duct Insulation by Kingspan is high-performance thermal insulation. It provides a neater, more seamless finish than non-rigid glass or rock mineral fibre ductwrap. Therma duct solutions are used to insulate ductwork and associated equipment outdoors. The closed-cell structure of the PIR core in the therma duct insulation restricts the transfer of heat within the material, making it ideal to insulate ductworks.

Thermaduct from Kingspan has low-emissivity foil facings on both sides, which ensure heat is reflected back and also works as a vapour barrier. It makes the thermaduct insulation moisture-resistant. 

They are perfectly designed for use on rectangular, circular and flat oval ductwork in HVAC / building services applications. Kingspan Therma Duct Insulation is an ideal solution for all types of projects. It can be used for both new build and refurbishment projects in the residential, commercial, institutional, light industrial and leisure sectors.
