Bespoke Biodiverse Green Roofs

When to specify...

Biodiverse roofs are designed to create a wide range of different habitats. This includes undulating substrates, piles of stone and dead wood, bare sandy areas and dew ponds. This matrix of different habitat allows the broadest range of flora and fauna to thrive. Bauder have worked with Buglife to produce specifications that ensure the roof areas maximize their ecological potential. 

Key features

■□ Fully FLL and GRO compliant systems.
■□ Buglife approved.
■□ Low system weight.
■□ Typically circa 150kg/sq m.
■□ Height of system typically 150-200mm.
■□ Water retention within drainage board.
■□ Plant selection is bespoke to the project and can incorporate native species vegetation to gain BREEAM credits.
 

Benefits

■□ Assists in maximising the building's potential to meet a BAP.
■□ Vegetation can be chosen to fulfill BREEAM requirements.
■□ System helps mitigate flooding.
■□ Substrate meets FLL European Standards.
■□ Low weight system allows for design flexibility.
