PUR roof ridge wedge PURBLOCK RDG

Roof PIR/PUR ridge wedge made of rigid polyurethane foam serves for effective thermal protection of roof structures. Eliminates thermal bridges in the ridge area. They are characterized by the lowest coefficient of thermal conductivity, high compressive strength and very low water 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

The product is available in slope variants of 10°, 15°, 20°, 25° and 30°, which allows perfect adaptation to various roof structures and ensures optimal thermal protection under all conditions.
