Kingspan Thermaroof TR26 Flat Roof Insulation Board 80mm

The Kingspan Thermaroof TR26 Flat Roof Insulation Board is a high-performance PIR insulation solution specifically designed for flat roofs with mechanically fixed single-ply waterproofing systems. Manufactured with a fibre-free rigid thermoset insulation core and low-emissivity composite foil facings on both sides, it provides outstanding thermal performance while helping to minimise heat loss and improve building energy efficiency.

Ideal for both new-build and refurbishment projects, the TR26 board is compatible with most mechanically fixed single-ply waterproofing systems and many green roof applications. Its resistance to water vapour transmission, excellent compressive strength, and lightweight design make it a reliable and easy-to-install solution for modern flat roof construction.
