Description
Protan has four green roof systems that can be applied to warm roofs to support diverse planting schemes. The systems are The Extensive Green Roofing System, The Biodiverse Green Roofing System, The Intensive Green Roofing System, and The Turf Green Roofing System.
Features:
The Extensive Green Roofing System:
- Supports low growing, lightweight and low maintenance planting schemes.
- Provides a consistent, colourful, and aesthetic finish that is largely self-supporting and able to withstand harsh weather conditions such as drought and frost.
The Biodiverse Green Roofing System
- Designed to create a natural habitat for local plants and insects and meet the environmental objectives of local, regional and national authorities.
- Biodiverse roofs can recreate natural habitats lost through developments on brownfield sites.
The Intensive Green Roofing System
- Supports diverse planting schemes including trees, lawns, coppices, and paved areas.
- It is possible to create a roof garden, including recreation areas and amenity space.
- Intensive roofs require higher levels of maintenance compared to other systems.
The Turf Green Roofing System
- Provides a traditional Norwegian green roof finish for pitched roof applications.
- In countryside areas, turf roofs help building developments to blend in with the rural environment.
- In towns and cities, they can soften the urban landscape.
Substrate:
- Ensure the structural deck is suitable for the loadings associated with protected roof systems.
- Concrete roof decking.
- Plywood WBP to BS 5268-2 and BS EN 636-3, minimum thickness 18 mm.
