You need a structural engineer to work out whether your roof is strong enough. The saturated weight of the GrufeTiles are as follows: 65kg per sqm for sedum and 75kg per sqm for brown wildflower and sedum and wildflower. However for other systems such as intensive or semi-intensive, the weight can vary with design.
Yes, the modules can be cut down with hand saw or a grinder. The cut edge then needs to be placed so it faces into the rest of the green roof so it’s supported by the next module.
We recommend the GrufeGuard if there is no upstand or parapet.
If you don’t have an upstand, we recommend you use the GrufeGuard. This will make the finished roof look neater and protect the edge. The 100m height of our GrufeGuard means it covers the GrufeTile but the plants can be seen above to create a stylish finish.
Each GrufeTile is 540mm x 540mm x 90mm. With vegetation the height can increase to 140mm (with the sedum GrufeTile. This can increase further when wildflowers are included).
The GrufeTile of your choice, protection fleece and accessories of your choice delivered on a pallet.
For interior applications, living canvas or moss art are ideal for a lower maintenance solution. For exterior applications, a lower maintenance solution would be a wire or climber system, which are left to establish naturally and need pruning annually and a health check every 3 months.
The module and irrigation system has a warrantee of 12 months from the date of installation.
