puren FAL-K cavity insulation TCG (WLS) 023/024

made of high-performance PUR/PIR (polyurethane) rigid foam insulating material, CFC- and HCFC-free, DIN EN 13165, TCG (WLS) 023/024, application type PUR 023/024 WZ, with double-sided aluminum coating.


  • Ideally suited as core insulation in outer cavity brick walls
  • Low superstructure because of slim thermal insulation (TCG (WLS) 023/024)
  • Lamination acting as vapor barrier
  • High compressive strength, Compressive strength at 10 % compressive deformation in accordance with DIN EN 826: > 100 kPa/150 kPa
  • Water-repellent and resistant to chemical impact
  • Insulating boards can be used either way up for cost-efficient installation with low off-cut waste
  • Water absorption acc. to DIN EN 12087: approx. 3 % by volume
  • Good resistance to ageing
  • Low weight and convenient format

A U-value of 0.24* can be achieved with a thickness of just 100 mm.
