Pitched roof board FKD 58SD
For use as anti-slip, drainage and water reservoir panel for pitched green roofs from 15° - approx. 30° roof pitch.
Product properties
| Material | EPS (expanded polystyrene, HBCD-free) |
| Nominal thickness | approx. 58 mm |
| Grammage | approx. 870 g/m² |
| Water discharge capacity | (DIN EN ISO 12958) i = 0.26 (approx. RP 15°): 1.94 l/(m*s) |
| Compressive strength filled | approx. 100 kN/m² |
Area of use
- As a drainage, anti-slip and water reservoir element for pitched green roofs with roof pitch up to 30° with an anti-slip effect due to the direct filling of the storage chambers. Vegetation mats are to be laid with stretch-resistant fabric lining from a roof pitch of 15°
Specific properties
- 100% EPS (expanded polystyrene)
- Free from HBCD (flame retardant)
- Shear load: Per structurally effective abutment in flow direction = 7.0 kN
- Drainage according to DIN 4095 - Depositing of water in the recesses
- Low weight
- Delayed guiding of water due to cascade-type spillway function of the chambers
- Water storage capacity after filling: 4.3 l/m² (at 15°) up to 3.4 l/m² (at 30°)
- Ideal for accurate fitting around roof protrusions and sloping vergeboard connections or chamfers
- Anti-slip laying and minimal tricking of the substrate on the protective layer due to accurate lateral interlinking and horizontal overlap
- Accurately fitting Z-shaped rabbet at upper and lower edge as well as side box toothing for the secure transfer of shear load in the flow direction as well as for substrate trickle protection, holder for irrigation hoses
- material is not permanently UV stable. Material must be covered with substrate immediately after installation. No permanent outdoor storage
