Older green roofs often used a permeable layer of rock aggregate such as scoria or gravel for drainage. It is made of a filtration veil and the polyamide monofilament fibre network layer. Protection layer rubber carpet it is a carpet made of polyurethane rubber and it protects the waterproofing and the insulation of the green roof.

The clay and silt content of materials used in a rock aggregate drainage layer should be 10 per cent by mass. The quality of the material its thickness weight and tensile strength. Benefits of green roofs. The growing substrate must be kept separate from the drainage layer with a filter sheet.

Drainage layer the green roof drainage layer provides you with a way to ensure there is nothing getting through and that excess water is drained away to avoid any waterlogging or increase in weight on the roof. Our protection mats are multifunctional products which are compatible with multiple membranes for use as a first layer of protection on the waterproofing membrane or above the root barrier. Systems secured by roof layer. Protection matting is installed directly on the waterproofing layer for root resistant membranes or atop the installed root barrier layer providing further uncertified protection against root penetration and doubling as a separation sheet.

The rock aggregate should also have a. This layer delivers protection against mechanical damage. Bauder sdf drainage layer material of the drainage layer polyamide monofilament weight of the drainage layer 400 g m. Drainage protection filtration layer it is used for lightweight green roofs terraces and has many functions.

Mechanical protection is necessary. The green roof drainage layer thickness makes sure that nothing can go wrong below offering a solid and effective guard. Benefits of green roofs. Green roof solutions protection mats are specially designed needle punched fleece constructed of 100 recycled polyester and polypropylene fibers.

The protection matting may provide some noise absorbing capability. In order to evaluate the compatibility of this layer the followings must be checked.
