Protan has four green roof systems that can be applied to cold roofs; the Protan Extensive Green Roof System, the Protan Biodiverse Green Roof System, the Protan Intensive Green Roof System, and the Protan Turf Green Roof System.

Features and benefits:

The Protan Extensive Green Roof System

• Supports low growing, lightweight and low maintenance planting schemes.
• The system will provide a consistent, colourful and aesthetic finish that is largely self-supporting and able to withstand harsh weather conditions, such as drought and frost.

The Protan Biodiverse Green Roof System

• Designed to create a natural habitat for local plants and insects and meet the environmental objectives of the local/ regional/ national authorities.
• Biodiverse roofs can recreate natural habitats lost through developments on brownfield sites.

The Protan Intensive Green Roof 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 Protan Turf Green Roof 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.
