AN UNRIVALLED RANGE OF SUBSTRATES FOR YOUR EXTENSIVE GREEN ROOFS
Extensive Green Roofs are designed to be low maintenance, lightweight systems, often with limited access to allow for inspections and maintenance. Extensive Green Roofs are mainly installed to increase local bio-diversity by providing additional habitat for plants and wildlife. Furthermore, an Extensive Green Roof is a nature based SuDS solution (Sustainable Urban Drainage System) because Green Roofs intercept rain water, which can be slowly released through evaporation and plant uptake. Should excess water need to be directed to an outlet, this will be at a much slower rate than would be possible with an impervious roof surface.
