50mm Kingspan Thermaroof TR26 Flat Roof Insulation Board 2400mm x 1200mm

Kingspan Thermaroof TR26 Flat Roof Insulation Board measuring 2400mm x 1200mm with a 50mm thickness. This high-performance rigid thermoset insulation board is specifically designed for flat roofs waterproofed with mechanically fixed single-ply membranes. Manufactured with a fibre-free insulation core and low emissivity composite foil facings, it achieves excellent thermal conductivity of 0.022 W/m·K, delivering high levels of thermal efficiency. The board is LPCB approved to LPS 1181 Part 1 and FM approved for Class 1 steel deck roof assemblies, confirming its suitability for demanding roof systems. Resistant to water vapour transmission and fully compatible with most mechanically fixed single-ply and green roof systems, it provides long-term thermal reliability and structural stability. Its rigid board format allows straightforward installation and consistent performance across large roof areas, with a 50mm thickness ensuring optimal thermal resistance for warm roof applications.
