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.
Derbigum NT is a bituminous roofing membrane that fits into the ecological NT roofs as a whole and is designed according to the circular economy. This roofing membrane is 100% recyclable and certified ATG and Cradle to Cradle.
