The RECTICEL EUROTHANE® GP 50 mm x 1200 x 2400 PIR Insulation Board is a high-performance rigid insulation solution designed for use in walls, floors and roofs where efficient thermal performance is required with a relatively slim build-up. With a low lambda value of 0.022 W/mK, it helps reduce heat loss and improve overall energy efficiency, supporting compliance with Building Regulations Part L.
Manufactured from rigid polyisocyanurate (PIR) foam, EUROTHANE® GP provides excellent thermal insulation in a compact profile, making it suitable for both new-build and refurbishment projects. The 50 mm thickness offers a practical balance between thermal performance and space saving, while the large 1200 x 2400 mm board size allows fast installation with fewer joints, improving thermal continuity. The product is 100 % PEFC certified (CU-PEFC-867959), supporting responsible and sustainable construction.
