RECTICEL EUROTHANE GP 25mm x1200x2400

The RECTICEL EUROTHANE® GP 25 mm x 1200 x 2400 PIR Insulation Board is a high-performance rigid insulation solution designed for use in walls, floors and roofs where space is limited but effective thermal performance is required. 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 delivers excellent thermal insulation in a slim profile, making it ideal for refurbishment and overlay applications. The 25 mm thickness provides effective insulation without significantly increasing build-up, 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 practices.
