Green roofs are becoming more and more popular, especially in densely populated urban areas, where it is important to use available roof space. Green areas and roof terraces increase value both for property developers and those who live in or use the buildings.
Ballasted or green roofs can be used for recreational areas or roof gardens. These solutions give architects and builders a lot of freedom for aesthetic design and contribute to more natural surroundings through the use of pebbles or vegetation. This often increases the value of the property and offers increased quality of life to those who live or work in the building.
The weight of the ballast requires the load-bearing structure to be engineered for this purpose.
Some types of green roofs commonly used is:
Extensive Green Roofs: These are lightweight and low-maintenance green roofs that typically have a shallow soil depth of around 2-6 inches. They are suitable for industrial buildings due to their cost-effectiveness and ability to handle harsh environmental conditions. Extensive green roofs usually consist of hardy, drought-tolerant plants such as sedums and mosses.
Intensive Green Roofs: Intensive green roofs are more like traditional gardens and can support a wider variety of plants, including shrubs, trees, and even small water features. They require a deeper soil depth, usually 6 inches or more, and can accommodate human activity. However, they are heavier and more expensive to install and maintain compared to extensive green roofs.
Protan membranes for green roofs are well suited for both new construction and rehabilitation projects. They have high quality and long life. The membrane is laid loose and requires no mechanical attachment to the roof surface - thus the vapor barrier is not punctured.
Intensive green roofs have a thick layer of soil and can be laid out as a roof garden with trees, shrubs and hedges.
Ballasted roofs can be used for living areas. The weight of the ballast requires that the load-bearing structure is intended for the purpose.
Turf roofs are most common in holiday homes, but are increasingly being used to soften the urban environment.
