Our Extensive Substrate (FLL) is a growing media designed for low maintenance extensive green roofs.  Extensive green roofs are generally planted with hardy plants that can tolerate low nutrient levels and little or no watering e.g. sedums, mosses and grasses.

Extensive green roofs are not generally designed as leisure spaces but for improving the aesthetics of our landscape and for providing provide vital habitat for insects, invertebrates, birds and the plants that we need to improve our environmental conditions.

Benefits of Extensive, Sedum and Bio Diverse Green Roof spaces:

• Increasing habitat for wildlife
• Inception of rain water providing much needed relief for our drainage infrastructure
• Storage of rain water, which can be used as grey water for requirements such as toilet flushing
• Increasing the lifespan of your roof by protecting it from the elements
• Improving the thermal performance of buildings (protection from heat, insulation from cold)
• Providing a more aesthetically pleasing landscape for those living and working in high-rise buildings
• Improved air quality as vegetation traps dust particles
• Plants remove un-wanted carbon dioxide from the atmosphere during photosynthesis
• Cooling urban areas through evaporation of water from plants and the soils absorbing heat
