Common uses of the grs air layers are.
Green roof water retention layer.
The vegetation layer must be put directly over the drainage course without using the filtration cover.
The secret of green roof water retention is green.
It is made of a filtration veil and the polyamide monofilament fibre network layer.
The green roof solutions air layers serve multiple purposes.
Technical specifications weight 120 kg sqm or 1 2 kn sqm layer height 120 mm vegetation forms sedum grass flowers water retention 80 ecological value maintenance cost cost factor description extensive green roofs are built in different parts of the earth with.
Extensive green roofs with water retention built on pitched surfaces of 5 15 inclination can be landscaped the same way as flat surfaces having only one important difference.
They are only accessed for maintenance.
There are two types of green roof.
Green roof solutions offers many different drainage layer options depending on system goals regarding water retention.
Extensive green roofs cover the entire roof area with lightweight low growing self sustaining low maintenance planting.
These products work in conjunction with the primary drainage component within the green roof system.
This means that the water leaves the roof as vapor.
Made of recycled non rotting polyester fibers for water and nutrient retention as well as a protection layer.
Green roofs are multi layered systems that cover the roof of a building with vegetation and or green landscaping over a drainage layer.
The most critical role of the drainage layer is to provide an adequate flow of water off the roof during and after rainfall.
Rain falls onto a relatively dry green roof and the green roof absorbs the water usually in pore spaces later the sun comes out and the plants use the rainwater to evapotranspire.
Bauder sdf drainage layer material of the drainage layer polyamide monofilament weight of the drainage layer 400 g m.
Their main function is to incorporate a thin layer of air within the profile of a green roof system while also providing lateral water movement.
Moisture retention and protection mat for extensive green roofs and ballasted roofs.
The basic anatomy of a green roof consists of vegetation growing medium filter membrane drainage layer waterproof root repellant layer roofing membrane support for plantings above thermal insulation vapor control layer and structural roof support.
Bitumen resistant biologically and chemically neutral heat resistant.
In all green roof scenarios substrate depths are completely dependent on the vegetation specified and the different drainage water retention layers are selected according to the levels of water required to be held within the construction.
Protection drainage and filtration.
Green roof system with high watre retention capacity especially designed to maximize precipitation retention.
