Thanks to its unique dimple structure and its innovative design its functions include.
Water retention roof.
The secret of green roof water retention is green.
Water storage and discharge delay.
0 01 0 17 at 2 roof pitch.
Discharge coefficient cs according to fll.
Suitable for blue roofs.
We need to think differently about the main purpose of a green roof.
The most critical role of the drainage layer is to provide an adequate flow of water off the roof during and after rainfall.
This means that the water leaves the roof as vapor.
Water retention is really important in case of pitched roofs because their drying trend is more pronounced.
The water only remains on the roof for a short period of time after rainfall.
Yes every green roof absorbs and buffers water.
Retention works like this.
Green roof solutions offers many different drainage layer options depending on system goals regarding water retention.
They have to be mounted linked to each other and floating over the protective layer of the waterproofing.
Intensive green roofs are landscaped environments with high amenity benefits including accessible planters or trees and water.
Such an extensive green roof will have a water retention capacity up to 44 l m and a surface weight in water saturated condition about 130 kg m.
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.
This type of water roof is called a water roof for rainwater retention.
These elements have high retention capacity and can be used for extensive and intensive green roofs with car traffic heavy vehicles etc.
Protection and efficient use of fresh water integration of natural water retention measures in river basin management.
The purple roof is the only concept that has been exposed to real life assembled testing in a professional setting.
High level of reduction of of water discharge during high intensity rainfall whilst retaining good drainage even for large roof areas peak discharge.
Core to the purple roof concept is making green roofs a true stormwater management tool by incorporating retention and detention.
System solutions with defined water retention.
Drainage and water retention element.
We believe the owner should see a return on investment of a green roof beyond merely meeting regulatory requirements.
The rainwater is drained off at a delayed pace using a narrower lower situated opening.
However a purple roof retains more water than any other green roof concept.
This frees up space for maximum real estate potential while realizing all other benefits such energy savings biodiversity habitat creation and.
Together they form the drainage layer of the ecological roof.
The water needs to be drained off to create sufficient storage capacity in time for the next rainfall.
