Dörr-Tirotect E-KV-40/Profi

Elastomer bitumen sub roof waterproofing sheet with synthetic fleece 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 has a red fleece and the downside has a fleece. With the red fleece lamination slip resistance is increased, and thus a safe walking on the sub roof layer possible.

The bonding is done by means of torching or welding procedure.



Dörr-Tirotect E-KV-40/Profi is used as a bitumen roof covering (especially for tile and metal covering) as a bitumen sub roof sheet for increased rain proof sub roofs.
