The roof allows the collection of rainwater to be reused in daily life.
Periods of drought are repeated every summer. Collecting rainwater to reuse it at the right time according to your needs becomes a necessity. The Derbigum Aquatop membrane and the Vaeplan are ecological and economical solutions for both renovation and new construction in colour or white..
Rainwater collected
Recovering rainwater means you can make serious savings on public distribution when you water your garden, flush your toilet or wash your car. You can even store the water on the roof to regulate the flow of rainwater into the drainage system or into the ground.
An ecological gesture without the risk of brown water, without an expensive filtration system thanks to the unique coating in the mass which preserves the natural characteristics of rainwater. The CEBEDEAU institute in Belgium, recognised and specialised in sustainable solutions for water treatment, confirms this.
Long lasting
The quality of the Derbigum Aquatop premium membranes validates a durability of 40 years. The BBA report confirms this after surveying 40-year-old roofs on various European sites.
The Derbigum Aquatop coating consists of a glass/polyester framework and a light grey, dark grey or white acrylic coating that is resistant to fungi (test method ASTM G 21 0).
At the end of its life cycle, Derbigum Aquatop is 100% recyclable for a more circular economy. The Vaeplan is also 100% recyclable.
Other functionalities of the roof
The white version of the Aquatop Reflective or Vaeplan membrane also makes it possible to reduce the temperature inside your building and increase the performance of the photovoltaic panels. They are also very aesthetic.
