puren cavity insulation

The insulating element is particularly suited for double paneled outer walls without air gap.

puren cavity insulation

puren cavity insulation TCG (WLS) 026/027/029

made of high-performance PUR/PIR (polyurethane) rigid foam insulating material, CFC- and HCFC-free, DIN EN 13165, TCG (WLS) 029 (d < 80 mm), 027 (d ≥ 80 mm), and 026 (d ≥ 120 mm), B2 class building material, application type PUR 026/027 WZ or PUR 029 WZ, with double-sided diffusion-open special fleece coating.


  • Good thermal insulation (TCG (WLS) 026/027/029)
  • Can be used from -20° C to +90° C
  • High compressive strength
  • Insulating boards can be used either way up for cost-efficient installation with low off-cut waste
  • Low dead weight and convenient board format
  • Easy to work with (sawing, cutting, drilling)
  • Water absorption acc. to DIN EN 12087: approx. 3 % by volume
  • Compressive strength at 10 % compressive deformation in accordance with DIN EN 826: > 100 kPa
  • Diffusion resistance coefficient: 40-200
  • High ageing resistance
  • Resistant to chemicals and solvents typically used in building & construction

A U-value of 0.33* may be achieved with a thickness of just 80 mm.
