DERBIGUM NT

Product catalog summary

Introduction
DERBIGUM NT is a bituminous waterproofing membrane designed with ecological considerations in mind, aligning with the principles of the circular economy. It incorporates New Technologies to facilitate the creation of environmentally friendly roofs.

Specifications
DERBIGUM NT is composed of 25% secondary raw materials sourced from recycled bituminous membranes. It features two reinforcements on the upper side: glass fibre and non-woven polyester, providing dimensional stability and resistance to tearing and perforation. The membrane is lightweight, with a roll weight of 25 kg, enhancing ease of handling.

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.
