High performance tapered insulation for flat roofs

Kingspan Thermataper TT47 is a high performance insulation with a fibre-free rigid thermoset polyisocyanurate (PIR) core.

It is designed to enhance water drainage for flat roofs waterproofed with full adhered single-ply, partially bonded built-up felt, mastic asphalt and cold liquid applied waterproofing.

 
Kingspan Thermataper TT47 is available with FM Approval to FM 4470 - please see the product brochure below or search 'Kingspan Therma' on the FM Approvals online listing website for the conditions of approval. 

There are three Kingspan Thermataper TT47 Systems that can be used:
  • Kingspan Thermataper TT47 - comprises high performance rigid thermoset fibre-free polyisocyanurate (PIR) insulation;
  • Kingspan Thermataper TT47-K Systems - combine the tapered insulation of Kingspan Thermataper TT47 with a premium performance rigid thermoset phenolic Kingspan Kooltherm packer board, providing a slimmer solution; and
  • Kingspan Thermataper TT47-O Systems - combine the tapered insulation of Kingspan Thermataper TT47 with a Kingspan OPTIM-R packer board, providing the thinnest solution.

New - Kingspan Thermataper TT47-K

MiscPhoto_Tapered_01_UK
Kingspan Thermataper TT47-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.
