Flame resistant flow-delay retention board
Advantages
- Flame resistant ⇒ tested according to EN 11925-2
- Class „E” fire performance ⇒ according to EN 13501-1
- High rainwater retention ⇒ nearly 12 l/m2 of water storage capacity
- Runoff reference value (C) 0,29 ⇒ water delay over 70% according to FLL1
- Microbiological resistance test (EN 12225) ⇒ barrier layer, protecting the waterproofing membrane against biological effects
