A separation profile is used between the gravel, vegetation and substrate layers. Manufactured from aluminium, they are installed on top of the drainage, at least 20 to 30 cm from the roof edge. The gravel is applied over the base of the profile and the Sedum is placed on the other side.
These profiles can also be used to create a “roof edge” to hold the green roof system in place, if you don’t have an up stand or parapet.
There are 2 sizes available: 60mm x 40mm or 110mm x 150mm x 2m long.
