Description
• 100% CFC, HCFC and HFC‑free rigid PIR foam core
• Double‑sided 7‑layer aluminium foil lamination for vapour tightness and durability
• Thermal conductivity λ = 0.022 W/m·K, enabling thinner insulation layers
• Long‑term water absorption < 0.6% – good moisture resistance
• High dimensional stability and shape retention (Micro Cell Technology)
• Reaction to fire class E (no melting or dripping, low smoke) under EN 13501‑1
