PUR roof attic wedge PURBLOCK KLN

A triangular wedge made of rigid polyurethane foam is used to create a smooth transition of waterproofing from the roof plane of a flat roof, a terrace to a subsequent vertical structure (attics, skylight frames, hatches, ventilation shafts, etc.). They are characterized by the lowest coefficient of thermal conductivity, high compressive strength and very low absorption.

coefficient of thermal conductivity λ=0.021 (W/mK)
water vapor diffusion µ ≤ 10
volumetric weight: ~33 kg/m3
heat resistance – 70°C to +140°C
reaction to fire E
Maximum compressive stress ≥ 250 kPa at 10% depressurization
Water absorption during short-term immersion ≤ 3%
dimensional tolerance +/-1%
resistant to aging, mold, rot and harmful insects
safe for health - they do not contain CFCs, HCFCs and formaldehyde
