Dörrkuplast® E-4 sk S

Elastomer bitumen sheet with synthetic fleece with a thickness of 4.5 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 has a silicone peel-off film.

The bonding is done by removal of the special foil. After that the product only requires slight torching onto the first layer. Therefore, it can be applied considerably faster and significantly reduces the required amount of gas. However, a homogenous bond with the first waterproofing layer must be ensured. Overlapping seams must be tightly torchsealed.



The Dörrkuplast® E-KV-4 sk S is used as a bitumen waterproofing sheet for flat roofs as top layer.
