About us.
Various international partners in the construction industry, including Sempergreen and Knauf Insulation, have set themselves the goal of optimizing water storage and rainwater management on a green roof. Intensive collaboration and extensive research have led to the creation of the innovative Detention Roof. The Detention Roof will radically change our perception of green roofs within climate-adaptive construction.
To measure is to know
The foundation of the Detention Roof lies in the Green Roof Diagnostics research laboratory in Virginia, USA. All kinds of rainfall can be simulated in this lab. Over 500 different tests were carried out on various green roof structures commissioned by independent international partners from the construction industry. Especially, the water-storing performance of each component in the green roof construction was examined.
The extensive research dataset has led to the development of the optimal green roof structure with regard to stormwater management. This concept was launched on the North American market under the name Purple-Roof Concept. In Europe this innovative concept is introduced into the market as "Detention Roof".
