Home > Companies > ANS Group Global > ANS GrufeKit Roof System

Green roof system for quick and easy installation using a protection fleece plus GrufeTiles which include the sedum and are clipped together on the protection fleece. The GrufeTiles also protect the waterproofing for a longer lasting roof.

No immediate aftercare is required at the time of installation. Each GrufeTile comes to site fully established with 12 month pre-grown vegetation eliminating the need of any irrigation.

The GrufeKit can be laid directly on top of the waterproofing surface with the protection fleece; while this can save costs, the side view of the module is not desirable for some projects. A stone border can also provide a pleasing visual effect. In some cases this is required on commercial buildings as a fire-break by planning authorities.

The aluminium GrufeGuard is optionally available for a more professional finish. A standard parapet or upstand is a good way to finish the roof and the GrufeKit can either run to the upstand or have a stone margin.

On sloped roofs with a gradient of 16° or less can be treated as a standard flat roof, with a gradient more than 16° GrufeGuard can be installed (fixed to the waterproof membrane using IFP's across the roof in front of the modules) or 4 x 2" restraining timber battens can be installed prior to waterproofing across the roof, depending on roof conditions (battens require a gap for water drainage every 1.5 m).
