Elastomer bitumen sheet with synthetic fleece with a thickness of 4 mm.
The bitumen sheet is root resistance according to FLL-procedure and EN 13948.
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 fine granule and the downside is foil-laminated.
The bonding is done by means of torching or welding procedure.
The Dörr-Gardentop E-KV-4K-wf is used as a bitumen waterproofing sheet for flat roofs especially for green roofs as a top or as intermediate layer sheet.
