Dörr-Tiralbit E-ALGV-1,5 sk

Self-adhesive elastomer bitumen vapor barrier sheet with fiber reinforced glass fleece and polyester-aluminumlaminate reinvorcement in a thickness of 1.2 mm.


Elastomer bitumen is highly elastic ("rubbery") and thereby remains flexible even at low temperatures.
The aluminumlaminate reinvorcement has a very high vapor barrier value (sd-value approx 1.500 m).


The surface texture upside is a polyester-aluminumlaminate silicone edge trim and the downside 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-Tiralbit E-ALGV-1.5 sk is used as bitumen vapor barrier sheet for flat roof constructions (profiled sheeting).
