Dörr-Tiralbit E-ALGV-3 sk/Safeguard

Self-adhesive elastomer bitumen vapor barrier sheet with fiber reinforced glass fleece and polyester-aluminumlaminate reinvorcement in a thickness of 2.7 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 foil-laminated and the downside has 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.

The outer half of the longitudinal seam overlap has a double-sided foil lamination. This guarantees a safe scarfing of the overlap because the inner section is already adhered by the self-adhesive bitumen mass. Therefore, a flame entry into the ground is prevented.



Dörr-Tiralbit E-ALGV-3 sk/Safeguard is used as bitumen vapor barrier sheet for flat roof constructions (Warm-, Duo Roof).
