The bituminous waterproofing membrane in line with the circular economy Composition of the membrane       DERBIGUM NT is a bituminous waterproofing membrane that thanks to the addition of New Technologies, opens the door to the design of ecological roofs according to the principle of circular economy. When used together with the cold adhesive DERBIBOND® NT we obtain the most ecological bituminous roof on the market. DERBIGUM NT consists of secondary raw materials obtained from recycled old bituminous waterproofing membranes. The specific formula with polymers gives exceptional, durable characteristics as well technically as ecologically. DERBIGUM NT is at the upper side fitted with two different reinforcements, one glassfibre and one non-woven polyester. These give the membrane a perfect dimensional stability and an excellent tear and perforation resistance. The weight of the roll (25 kg) makes the handling of the membrane easier. Underneath, the DERBIGUM NT is fitted with 1 side strip with a PE thermofusible film and 1 with talcum.
