Protection drainage and filtration.
Roof detention system.
Almost all of the rain that falls onto a fully saturated profile will quickly drain through and flow underneath a traditional green roof profile.
Roofblue can do the following.
When used with control flow drains roofblue expands the usefulness of a green roof system as a stormwater management tool.
Purple roof is the simplest and least expensive solution if you would like a detention green roof.
It is made of a filtration veil and the polyamide monofilament fibre network layer.
It is this delay that what saves us from floods.
Rooftop detention is the heart of blue roof technology.
The foundation of the detention roof lies in the green roof diagnostics research laboratory in virginia usa.
A standard sponge roof can be upgraded from a retention oriented green roof to a detention retention oriented green roof for 10 20 m 2 1 2 sqft.
All kinds of rainfall can be simulated in this lab.
Blue roofs are non vegetated source controls that detain stormwater either releasing it more gradually to the sewer system or storing it for beneficial reuse.
Rooftop detention also known as a blue roof is designed to provide temporary storage and slow release of stormwater runoff.
Thus detention has a time component added.
Reduce the burden on stormwater systems.
For a detention facility where the outflow is controlled by means of an outlet orifice tube subject to a head which increases as the depth of storage increases in a storage facility with an approximately uniform area with respect to storage height and for roof detention by means of.
It has been evaluated and tested by green roof diagnostics.
The urbanscape detention green roof is a complete system which consists of a detention layer storage layer a growing media a unique patented rock mineral wool and a vegetation layer.
The goal of a detention oriented green roof is to delay peak runoff so that sewage systems have time to drain.
This technique is most commonly used in dense urban areas where other methods of stormwater detention are impractical.
This roof can then detain 2 5 5cm 1 2 of water for anywhere between 1 10 hours.
Over 500 different tests were carried out on various green roof structures commissioned by independent international partners from the construction industry.
Instead of running off the roof via gutters and downpipes the water is temporarily stored or allowed to pond on the surface and then released slowly so that it can drain away gradually.
It is a relatively simple concept that results in a controlled flow system of rainwater from the roof.
The liveroof integrated roofblue riser is engineered to provide temporary water detention underneath all liveroof systems.
