Fentrim 230 grey is the optimal solution for permanent airtight and driving-rain proof sealing of window and door frames in solid construction on the exterior. As with all tapes in the Fentrim family, Fentrim 230 grey is a completely primerless solution for all substrates — including masonry.
According to the rule “less permeable on the inside than on the outside”, the white colored window joint tape Fentrim IS 20 perfectly supplements Fentrim 230 grey.
For a non pre-folded version of this tape, try Fentrim 430 grey.
