New - Kingspan Thermataper TT44-K

MiscPhoto_Tapered_01_UK
Kingspan Thermataper TT44-K combines tapered insulation with a premium performance Kingspan Kooltherm packer board, providing a slim solution for use on new and existing roofs with timber or concrete decks.

With a thermal conductivity of 0.018 W/m·K, the Kingspan Kooltherm packer board helps to minimise the overall system thickness required to achieve a desired U-value. Typical thickness savings of 20 - 40 mm could be achieved, dependent on the individual scheme and build-up, when compared with a full Polyisocyanurate (PIR) system.
