Pitched Green Roofs up to 25°

The core element of the system build-up for roofs with a pitch of up to 25° is the Floraset® FS 75 drainage element. Due to its profiled design and studs facing upwards Floraset® FS 75 is the perfect drainage element to install a green roof on a sloping roof up to 25°. It prevents erosion and safely transfers shear forces.
