100mm Recticel Eurothane GP PIR Insulation Board is a BBA certified thermal solution that can be used in a variety of building applications. It is lightweight, making it easy to handle, and can be cut to size and installed with ease. Comprised of a rigid foam polyisocyanurate (PIR) core, these 100mm Recticel Insulation boards are faced on both sides by a layer of aluminium foil that acts as a gas diffusion facer. They are moisture resistant and therefore offer consistent thermal performance over a long period of time. With a thermal conductivity of 0.022 W/mK, 100mm Recticel Eurothane boards offer a high level of thermal performance for walls, floors, pitched roofs and ceilings, making them one of the most popular insulation products in the UK. At 100mm thick, this is the most popular size within the Recticel Eurothane GP range.
