The bituminous waterproofing membrane in line with the circular economy

  • DERBIGUM NT is a bitumen-plastomer membrane developed on the basis of in-depth knowledge of the raw materials used in DERBIGUM SP FR.
  • It differs from DERBIGUM SP FR by the addition of DERBITUMEN, a raw material resulting from the recycling of application waste and old selected bituminous roofs. Its specific formulation gives it exceptional properties in terms of durability and ecological characteristics.
  • The membrane is provided with two distinct reinforcements offset upwards. Glass fleece and polyester fleece, which give the membrane perfect dimensional stability and excellent tear and puncture resistance.
  • The lower face has on one side a talc-coated edge for a glued or welded application, and on the other side a hot-melt polyethylene edge for exclusive flame application.
