ZinCo Semi Intensive

The System
ZinCo Semi-Intensive Green Roofs provide a varied landscape that can include shrubs and woody plants, but still have a low build-up. Ecological benefits are combined with access for recreational use.
North Harringay School An inspirational project at North Haringey School involved creating a roof garden, giving amenity space back to the community. The roof garden comprises Alumasc’s Derbigum waterproofing and ZinCo green roof build up.
