RECTICEL EUROTHANE GP 100mm x1200x2400 100% PEFC certified CU-PEFC-867959

The RECTICEL EUROTHANE® GP 100 mm x 1200 x 2400 PIR Insulation Board is a high-performance rigid insulation solution designed for walls, floors and roofs where low U-values and Part L compliance are required. With an excellent lambda value of 0.022 W/mK, it delivers outstanding thermal efficiency, helping to significantly reduce heat loss and improve building energy performance.

Manufactured from rigid polyisocyanurate (PIR) foam, EUROTHANE® GP provides high thermal resistance with minimal thickness, making it ideal for modern construction and refurbishment projects. The 100 mm thickness can achieve very low U-values across a range of applications when installed as part of a compliant build-up. Supplied in large 1200 x 2400 mm boards, it enables fast installation with fewer joints, improving thermal continuity. The product is 100% PEFC certified (CU-PEFC-867959), supporting responsible and sustainable construction.
