Flat Green Roof Systems

Flat roof system

Flat roofs between 0 and 5 degrees are perfect for green roofs. Equal weight and retention of water enables a healthy green roof that can prolong the life of the waterproofing layer as well as the extensive benefits they provide.

Technical specifications

Pitch: 0-5°

System depth: 80-110 mm

Saturated weight: 80-85 kg/m2

System Structure

^{Sedum blanket – 30mm}

^{Pre-cultivated Sedum-mix blanket, consisting of a mix of 10 to 12 different types of Sedum. Vegetation percentage on delivery: at least 95%.}

^{Extensive substrate – 40mm}

^{Extensive roof garden substrate consisting of lava, pumice and compost. Produced in accordance with FLL guidelines.}

^{Drainage board with filterfleece – 10 to 40mm}

^{The thickness of the drainage layer will depend on the roof structure and the water storage capacity required, depending on the climate.}
