GT Drain N25
Description
GT Drain N25 is a drainage and water storing board, CE-certified according to standard EN 13252, with absorption openings, made of recycled polystyrol (HIPS) for extensive and semi-intensive green roof application. The drainage and water storing element has an excellent water storing- and water flow capacity with a very high compressive strength.
Benefits
- Increased water storing capacity – 13 l/m2 rainwater retention
- Terrace build-up application possible – 397 kN/m2 compressive strength with only 2 mm deformation
- 3-level waterflow system – stormwater channel with outlet openings at the elements' side, rainwater channels between the dimples and slow-water flow surface below the dimples
- Rounded element corners – reduced risk of injury for workers and safety for the waterproofing membraine
- Simple logistic – product on 2 x 1 meter stackable pallets
- Fast consigment – exactly 2 m2 per element, fast logistic/loading on the construction site and in the warehouse
- Erosion control effect on pitched roofs – elements can be fixed to each other by plastic clips
- Two volcano design water-outlet elements according to standard UNI 11235
- Environmental Product Declaration (EPD): verified and comparable product information about the life-cycle environmental impact (“carbon footprint”), relevant information for sustainable built environment certifications (LEED, BREAAM, DGNB, etc.).
