Protan UK Green Roof System - Prefabricated G membrane - Cold Roof Construction

Protan has four green roof systems that can be applied to cold roofs:

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 is 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.
