Riwega FDB EXT

FDB EXT is a breathable adhesive tape.‎ External use that does not obstruct the passage of steam.‎ It waterproofs the installation joint of the windows to the wind.‎ Available variants: FDB EXT AC 75, FDB EXT AC 100, FDB EXT AC 150, FDB EXT AC+AC 75, FDB EXT AC+AC 100, FDB EXT AC+AC 150, FDB EXT AC+WB 75, FDB EXT AC+ BU 100, FDB EXT AC+BU 150 A critical point in the air and wind tightness of the building envelope is the window joint.‎ Careful attention must be paid to the window connections: filling the joint between the window and the masonry with foam and plaster is not sufficient to create air and wind tightness, as not all building foams can create an airtight layer.‎ Riwega's window and door solutions: FDB tapes (from the German Fenster Dicht Band - Window Sealing Tape) were created precisely to create the air and windtight connection between masonry and subframe, or in the absence of a subframe, between masonry and window easily and quickly.‎ Further info from manufacturer on FDB EXT Riwega
