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.
Roof detention system.
This technique is most commonly used in dense urban areas where other methods of stormwater detention are impractical.
Rooftop detention is the heart of blue roof technology.
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.
Bauder sdf drainage layer one side laminated version is also avaliable.
Reduce the burden on stormwater systems.
The foundation of the detention roof lies in the green roof diagnostics research laboratory in virginia usa.
Over 500 different tests were carried out on various green roof structures commissioned by independent international partners from the construction industry.
The goal of a detention oriented green roof is to delay peak runoff so that sewage systems have time to drain.
It has been evaluated and tested by green roof diagnostics.
Rooftop detention also known as a blue roof is designed to provide temporary storage and slow release of stormwater runoff.
This roof can then detain 2 5 5cm 1 2 of water for anywhere between 1 10 hours.
When used with control flow drains roofblue expands the usefulness of a green roof system as a stormwater management tool.
It is this delay that what saves us from floods.
Urbanscape detention layer t5.
Roofblue can do the following.
Protection drainage and filtration.
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.
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.
It is a relatively simple concept that results in a controlled flow system of rainwater from the roof.
Thus detention has a time component added.
Purple roof is the simplest and least expensive solution if you would like a detention green roof.
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.
All kinds of rainfall can be simulated in this lab.
It is used for lightweight green roofs terraces and has many functions.
