SOPRANATURE DRAIN 4+1h

Sopranature 4+1h is a vapour-permeable dimpled drainage sheet made out of recycled high impact polystyrene (HIPS) combined on the back of the sheet with a filter layer made from a non woven geotextile and on the front with a protection and separation layer mad from a geotextile.

The geotextiles are glued to the dimpled sheet, preventing the geotextiles being pushed in between the dimples. The sheet has a high compressive strength and excellent creep resistance. Sopranature 4+1h prevents waterlogging in the substrate layer, the build-up of hydrostatic pressure on the waterproofing membrane and protects it against mechanical loads and ensures that water vapour is able to evaporate.

Sopranature 4+1h is applied as a filter, drainage and protection layer in the extensive and intensive Green Roof system.
