Dörr-Gardentop E-4 sk-wf

Self-adhesive Elastomer bitumen sheet with a synthetic fleece reinforcement in a thickness of 4 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 is foil-laminated and the downside has a silicone peel-off film. The bonding is done by removal of the special foil. In order to ensure save adhesion of the sheet, we recommend a minimum temperature of +10°C (air and surface) during the application. If necessary, the self adhesive sheet shall additionally be activated with a hot air gun or a flame gun.



Dörr-Gardentop E-4 sk-wf is as a self-adhesive bitumen waterproofing sheet used for flat roofs, especially for green roofs as an intermediate layer.
