Our sustainable roofs
A standard flat roof consists of an underlayer and a top layer. The waterproofing membranes in our NT range contain at least 20% recycled bitumen and we are investigating how we can go on increasing this percentage. The more we collect and recycle, the more recycled bitumen (Derbitumen®) we can incorporate into our products.
Even our Derbigum reinforcements based on fiberglass and polyester are made from recycled material. Our Derbigum NT waterproofing system is ATG-certified while Derbigum NT and Derbicoat NT membranes are Cradle-to-Cradle-certified.

Thanks to our circular program, we are able to develop three products containing recycled bitumen. This allows us to deliver the same quality while significantly reducing our CO2 emissions.
