Urbanisation and climate change – greater quality of life with green roofs

Better air, relieving pressure on the sewer system, and creating new habitats are just three of the many advantages of a green roof, making it an important component in climate-friendly urban development.

OPTIGRÜN green roofs thus make a crucial contribution to achieving better quality of life in our cities

Ecological compensation
Our systems for optimum green roofs are an important contribution to climate compensation. As a recognised measure of the impact compensation regulation under nature protection law, green roofs offer new living spaces for people, plants and animals.The large storage capacity and evaporation of precipitation on the roof relieve pressure on the sewer system, especially in the event of heavy rainfall. At the same time, the green roof efficiently cools both the surrounding area and the building and also contributes to air humidification and fine dust filtration. As protection against extreme temperatures or hail, green roofs also extend the service life of waterproofing.

Multifunctional roof design
A green roof is an upgrade for any building. It looks good, offers multiple benefits with numerous functions and even saves money. In order to make the right decision, it is essential to identify the respective requirements and to use the best solution for each application. Our motivation is the idea of designing living spaces better, taking the next step for tomorrow today and further extending our technological lead. To do this, we develop innovative systems that impress with their functionality from both an ecological and an economic viewpoint.
