GREEN - Roofing System
Wonderful, turning your roof into a green oasis. Something for everyone: do you opt for a simple green roof or do you prefer a real vegetable garden? Everything is possible!
In principle, green roofs can be applied to any surface, as long as the load-bearing capacity of the roof allows the permanent load on the green roof. We can divide green roofs into two types, based on the required maintenance:
Extensive green roofs
This type of green roof requires little maintenance and can consist of mosses, succulents and herbs. These slow-growing plants do not need to be pruned or mowed and, moreover, can live without water for a long time. No problem so if it is not raining.
Not only are the plants able to store a lot of water, but the excess rainwater will also be released in a delayed manner. After all, an extensive green roof acts as a natural buffer in the event of heavy rainfall.
Not only flat roofs but also slightly sloping roofs (1-35 °) can be provided with an extensive green roof. The green roof also acts as extra protection for the roof against UV radiation, extreme temperatures and noise.
Intensive Green Roofs
The maintenance level of an intensive green roof is a lot higher than with an extensive green roof and, just like with a traditional garden, depends on the choice of plants. For example, grass will have to be mowed frequently during the summer months and trees and shrubs need to be pruned occasionally.
Just as with an extensive green roof, excess rainwater will be released in a delayed way since the green roof acts as a natural buffer. The green roof also acts as extra protection for the roof against UV radiation, extreme temperatures and noise.
The considerable substrate layer does, however, create greater structural requirements and you must take this into account in the design phase of the building.
