Traditional Green Roof System

from £34.50 ex VAT / m2

The build-up layers of this traditional green roof system form the basis for a sustainable green roof.  Each of our Systems consist of 3 layers including: Drainage, Substrate & Sedum vegetation blanket. The 50mm substrate layer is developed to FLL guidelines and is a nutrient-rich substrate that ensures healthy and strong sedum planting.  There are 6-8 different species of hardy succulents, each chosen for their ability to absorb and retain water and to thrive in adverse weather conditions. The plants are grown on a coconut fibre matting using a special cultivation substrate over a 12 month period and are supplied with 95% coverage, ensuring that an instant green roof is achieved.

For larger projects over 50m2, please contact us on info@thegreenroofcompany.co.uk to ensure the best pricing.
