Oxidized bitumensheet with fiber reinforced glass fleece and polyester-aluminumlaminate reinvorcement in a thickness of 3.8 mm.
The aluminumlaminate reinvorcement has a very high vapor barrier value (sd-value approx 1.500 m).
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-Tiralbit ALGV-4K is used as a vapor barrier sheet mainly for flat roof constructions (Warm-, Duo Roof) and as temporary construction waterproofing.
