Economy Roof
A popular standard construction for extensive Green Roofs (0-5°)
The ECONOMY ROOF system has proven itself in practice for decades. Drainage takes place via a drainage board (FKD), which is also well-suited to non-pitched roofs. The ECONOMY ROOF is particularly resistant and can be used on most standard roofs.
