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.
