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.
