Kingspan Thermaroof TR26 Flat Roof Insulation Board 60mm

The Kingspan Thermaroof TR26 Flat Roof Insulation Board is a high-performance PIR insulation solution specifically designed for flat roofs waterproofed 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 delivers exceptional thermal efficiency while helping to reduce heat loss and improve overall building energy performance.

Suitable for both new-build and refurbishment projects, the TR26 board is fully compatible with most mechanically fixed single-ply waterproofing systems and many green roof applications. Its lightweight construction, moisture resistance, and straightforward installation make it ideal for fast-track building programmes while providing long-lasting thermal performance.
