Dermabit 4250 (3250,5250) is a plastomeric bituminous waterproofing membrane obtained from distilled asphalt, modied with thermoplastic resins (APP, IPP). The membrane is reinforced by a non-woven polyester of 250g/m2 nominal weight. For the plain membrane, both surface of the membranes are covered with a plastic form that is easily torched and for the Mineral membrane, the upper surface of the membrane is covered with natural slate granules that are easily torched. The compound is a UV ray resistant, thermally stable and flexible at low temperatures and for the Minaral upper surface of membrane is covered with natural slate granules that are easily torched.

Characteristics
