Elastomer bitumen sheet with copper tape + fiber reinforced glass fleece with a thickness of 5 mm.
The bitumen sheet is root resistance according to LDA-Procedure.
Elastomer bitumen is highly elastic ("rubbery") and thereby remains flexible even at low temperatures.
The copper tape + fiber reinforced glass fleece is particularly resistant against root entry.
The surface texture upside has fine granule and the downside is foil-laminated.
The bonding is done by means of torching or welding procedure.
Dörr-Gardentop E-Cu-5K-wf is used as a bitumen waterproofing sheet for flat roofs particularly for green roofs as root resistant top layer.
