Dörr B 105/25

DÖRR B 105/25 is a bitumen block from oxidized bitumen (blown bitumen).

It is used for bonding bituminous roofing sheets and cellular glass insulation.
B 105/25 is melted in commercial bitumen digesters to reach the necessary processing viscosity. Processing temperatures above +230 ° C are to be avoided, the processing temperature is approximately +190 to +200 ° C.


For full-surface bonding of bituminous waterproofing layers: about 2.0 to 2.5 kg / m².
For full-surface bonding of cellular glass insulation: approximately 4.0 to 6.0 kg / m².
