Featuring a low emissivity foil facing, it's ideal for various floor, wall and roof applications. The excellent thermal conductivity of 0.022 W/m.K reduces significantly the thickness of insulation required to meet the target U-value. In addition, the low emissivity foil facing boosts thermal performance in sealed cavity air spaces, further improving U-values.But that's not all! Available in a size of 2400mm in length by 1200mm in width by 20mm in thickness, this versatile PIR insulation board is light and rigid, making it easy to handle and install.
