Dörrkuplast® E-GG-4K

Elastomer bitumen sheet with woven glass with a thickness of 4 mm.


Elastomer bitumen is highly elastic ("rubbery") and thereby remains flexible even at low temperatures.
The woven glass reinforcement is particularly dimensional stable, smooth in process and has excellent resistance to tearing.


The surface texture upside has fine granule and the downside is foil-laminated.
The bonding is done by means of torching or welding procedure.



Dörrkuplast® E-GG-4K is used as a bitumen waterproofing sheet for flat roofs as as intermediate layer sheet.
