Bulk Buy - 100mm Recticel Eurothane GP PIR Insulation Board 2.4m x 1.2m

At 100mm, Recticel Eurothane GP is one of the higher-resistance boards in the PIR range, used in pitched and flat roofs, between and below timber joists, concrete slab floors, and framed or plasterboard-lined walls. With a thermal conductivity of 0.022 W/mK the board provides a thermal resistance of approximately 4.55 m²K/W, suited to applications where a demanding U-value target needs to be met within a workable build-up depth. The foil facing acts as a vapour control layer and the square edge profile keeps joints tight, limiting thermal bridging. The board holds its dimensions under temperature, humidity, moisture and UV exposure, and is used on commercial and domestic projects across new build and refurbishment. Buying in bulk reduces the cost per board on larger jobs. Benefits Thermal conductivity of 0.022 W/mK Thermal resistance of approximately 4.55 m²K/W at 100mm Moisture resistant; will not deteriorate when exposed to moisture Class 1 surface spread of flame to BS 476 (part 7) Compatible with underfloor heating Foil facing acts as a vapour control layer Square edge profile to limit thermal bridging at joints Cuts on site with a sharp knife or insulation saw Suitable for commercial and domestic buildings Manufactured with zero ODP and low GWP blowing agents Bulk ordering reduces material cost on larger contracts Good to know PIR is moisture resistant but not waterproof. Store in a dry environment and out of direct sunlight.
