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%.
