Greenfix DIY extensive green roof for quick installation
With a Greenfix extensive green roof, you achieve a lightweight and low-maintenance green roof structure for flat and gently sloping roofs. You combine water buffering, additional insulation, and protection of the roofing membrane in a single system that is suitable for both new construction and renovation.
Due to the limited substrate layer and vegetation, you opt for an efficient, low-load solution, ideal for projects where technical simplicity and durability are central.
