ABG Biodiverse Green Roof with Roofdrain 25mm Drainage Board
Verified by manufacturer today
The Biodiverse Green Roof is commonly used to replace or extend an area of local habitat and enhance biodiversity.
Application
Biodiverse green roof build up, suitable for flat or pitched roofs and new build or retrofit applications.
Description
The ABG Green Roof biodiverse system comprises:
- Engineered growing media:
ABG peat free media derived from sustainable, recycled, UK sourced materials. Using a specifically developed, light-weight growing media reduces the load on the roof.
- Surfacing:
A vegetation layer, such as wildflower seed and sedum plug plants and habitat enhancement features (e.g. hibernaculum stone and log piles).
- Roofdrain 25mm drainage / reservoir board:
Utilising a drainage composite such as ABG Roofdrain reduces the risk of over saturation of the soil media and planting during periods of heavy rainfall. The high strength drainage core of the ABG Roofdrain product is designed to be used for higher load biodiverse green roof system applications, with a typical depth of between 80 - 150mm of growing media and with typical loads ranging from 100 – 200kg per m2. The product consists of a combination of a cuspated core with a geotextile bonded to the upper face to prevent soil ingress. It is manufactured in the UK from up to 95% recycled material. It provides excellent drainage over the whole base area of the soil layer, as well as providing additional waterproofing protection.
Features and benefits:
- Added protection for waterproofing layer
- Contributes to overall BREEAM assessment
- Reduces whole life costs of the building and improves energy efficiency
- SuDS solution acting as the first stage in the treatment train
- Creates habitat to improve local biodiversity
- Noise reducing
- Extracts pollutants and improves air quality
