The bituminous base sheet in line with the circular economy Composition of the membrane DERBICOAT NT is a bituminous base sheet that ts in the context of ecological NT roofs and which is designed according to the principle of circular economy. In combination with the DERBIBOND NT and DERBIGUM NT, the most ecological two-layered bituminous roof on the market is obtained. DERBICOAT NT consists of secundary raw materials obtained from recycled old bituminous waterproong membranes. The specic formula with polymers gives exceptional, durable characteristics as well technically as ecologically. DERBICOAT NT has a glass/polyester reinforcement that gives the membrane a high tear resistance. Ecological characteristics % secundary raw materials (obtained from recycling) : 30 % (certicate PwC). Calculator environmental advantage online available on www.derbigum.com Recycling : this roong membrane is 100% recyclable.

DERBICOAT NT can be used as a vapour barrier on wooden panels, planks and steel deck. The application of the DERBICOAT NT can be done with mechanical xations, completely welded or cold bonded (Max. slope 15%). DERBICOAT NT is especially recommended when a high tear resistance is required.
