Flat roof insulating element puren® PIR KOMPAKT SD+ Class C TCG (WLS) 026/027

These puren class C insulating elements are specially suited for cost-effective insulation with low cut-off waste of warm roof systems with and without slope not allowing water seeping in and requiring increased compressive strength and fire protection.

puren PIR KOMPAKT SD+ Class C

puren® PIR KOMPAKT SD+ Class C TCG (WLS) 026/027

Insulating elements for our puren PIR KOMPAKT safety roof, available as sloped insulation or flat panels, made of high-performance PUR-/PIR (polyurethane) rigid foam insulating material, DIN EN 13165, TCG (WLS) 026 d ≥ 120 mm, or 027 d≥ 80 mm < 120 mm, building material class C-s3, d0 acc. to EN 13501-1, application type PUR 026 DAA ds, or PUR 027 DAA ds, not laminated.


  • High-performance insulation for warm roof systems with no moisture seeping in
  • Slim superstructure providing optimum thermal insulation
  • Suitable for installation into hot asphalt
  • Safe processing of roofing foil by pouring and rolling or welding it in
  • Insulating elements may be used either way up for cost-efficient fitting with low off-cut waste
  • Highest safety through bonding with elastomer bitumen throughout the entire surface and all joints
  • To be used from-20 °C to +110 °C
  • Short-term temperature resistance: +250 °C
  • Compressive strength at 10 % compressive deformation acc. to DIN EN 826> 150 kPa
  • Water absorption in accordance with DIN EN 12087: approx. 3 % by volume
  • Non-crushing, suitable for installing into high-load surfaces such as park-decks
  • Laminated roof structures offer high resistance to wind suction forces
  • Low additional load on the roof construction
  • High ageing resistance
  • Resistant to chemicals and solvents typically used in building & construction and to many more

A U-value of 0.18* can be achieved with a thickness of just 140 mm.
