PUR board/panel PURBLOCK 035

PUR thermal insulation boards / panels made of rigid polyurethane foam without lamination / facing are characterized by the lowest coefficient of thermal conductivity, vapor permeability / diffusion of water vapor, 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
