AV 200sv Drainage System

High-performance CE-marked drainage system with an innovative dimple design made out of recycled high impact polystyrene. The core of the AV Drainage System is a perforated, vapour permeable dimpled sheet with a high compressive strength and a construction height of approx. 13 mm. A nonwoven geotextile is bonded to each dimple as a filter layer. A vapour-permeable geotextile is glued to the back of the perforated core as a separation and protection layer to protect the XPS (Extruded Polystyrene Foam) insulation panels. Application The AV 200sv Drainage System is a component of the Nophadrain Podium Deck System that acts as a filter, drainage, protection and separation layer on an inverted roof construction. When the roof has 700 kPa limited falls or when longer drainage length is needed, the construction height can be increased to approx. 16.5 mm (AV 200hsv Drainage System).
