Dörrkuplast® E-KV-5S

Elastomer bitumen sheet with synthetic fleece with a thickness of 5.2 mm.


Elastomer bitumen is highly elastic ("rubbery") and thereby remains flexible even at low temperatures.
The synthetic fleece reinforcement is particularly durable, has excellent tensile strength and is resistant to static and dynamic stresses.


The surface texture upside has schist granule and the downside is foil-laminated.

The bonding is done by means of torching or welding procedure.



The Dörrkuplast® E-KV-5S is used as a bitumen waterproofing sheet for flat roofs as top layer.
