Green Roof Protection Layer

Systems secured by roof layer.

Green roof protection layer.

Benefits of green roofs. Many green roof systems feature a water storage layer incorporated into the drainage layer so as to have a reserve of water for bottom up irrigation of the vegetation. Bauder sdf drainage layer material of the drainage layer polyamide monofilament weight of the drainage layer 400 g m. As a general rule the more the roof is trafficked the higher the level of protection required for example extensive green roofs would generally experience much lower levels of traffic damage during maintenance than publicly accessed areas.

The growing substrate must be kept separate from the drainage layer with a filter sheet. The green roof drainage layer thickness makes sure that nothing can go wrong below offering a solid and effective guard. 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. Benefits of green roofs.

This layer delivers protection against mechanical damage. In order to evaluate the compatibility of this layer the followings must be checked. 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.

The quality of the material its thickness weight and tensile strength. The water storage means sprinkler irrigation can be used at greater intervals and in certain favourable situations irrigation can be done away with altogether. The clay and silt content of materials used in a rock aggregate drainage layer should be 10 per cent by mass. Protection drainage and filtration.

It is made of a filtration veil and the polyamide monofilament fibre network layer. Older green roofs often used a permeable layer of rock aggregate such as scoria or gravel for drainage. Systems secured by roof layer. Drainage protection filtration layer it is used for lightweight green roofs terraces and has many functions.

Mechanical protection is necessary. 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.
