Blue roof system summaries 

Within a Bauder Blue Roof Ballasted System, rain water accumulates in the void whilst Bauder's unique flow restrictor (fitted at each outlet) allows precise control of the roofs discharge rate and enable large volumes of water to be attenuated at roof level.

Intensive landscapes are often specified above blue roofs. The landscaped areas naturally delay and reduce rainwater runoff, and this combined with the blue roof void (Bauder's Attenuation Cell 100) and flow restrictors allows precise control of the roofs discharge rate and enable large volumes of water to be attenuated at roof level.

Green roofs are an ideal partner for blue roofs as they will naturally delay and reduce rainwater runoff from the roof. Green roofs, when combined with the blue roof system (Bauder's Attenuation Cell 100), and flow restrictors allow the precise control of the roofs discharge rate and enable large volumes of water to be attenuated at roof level.

This specific type of biodiverse roof is designed to incorporate as many types of habitat as possible giving a home and food source to invertebrates and pollinators.
