General info installation
ECCOsedum green roof tiles can be placed on a flat and on a sloping roof, but there are two parameters to consider during the installation process:
- Prevention of washout or shearing of the substrate
- Shearing of the entire green roof system due to the incline of the roof
For the above reasons, there is a limit to the roof incline. Based on the gradient and the corresponding customised roof structure, the following categorisation may be made:
- Gradient between 0 and 3° (0 to 5%) and gradient exceeding 3° (more than 5%)
The ECCOsedum system can be placed without any additional precautions.
- Gradients higher than 15 to 20° (27 to 36%)
Here, an additional system is installed to prevent the shearing of the substrate layer. Such systems can be divided into two groups (a) systems that reduce the gradient by means of a stepped system (similar to a terrace structure) or (b) systems that divide the substrate layer into compartments by means of a slat system. The distance between adjacent slats is determined by the gradient.
