Optigrün Retention roof flow control extensive

Optigrün

A green roof provides a better microclimate. Our green roof system RETENTION ROOF FLOW CONTROL also keeps the water in the cities and helps to store it there. This turns the city into a sponge. Water is stored when it is in abundance so that it is available when it is urgently needed.
