SIGA Fentrim 430 Grey - 4"

Fentrim 430 Grey - 4" is the complete window and door sill-flashing tape you've been waiting for. With more adhesive and adhesion strength than the Wigluv tape, this tape will stick to most substrates and building materials; it will even stick to porous and rough substrates - like concrete and OSB - without the need for a primer. You can even apply Fentrim in cold weather conditions!

SIGA Fentrim 430 Grey - 4" tape has a slight perm rating, making it breathable so as to prevent condensation buildup, rot and mold. The gray, single-sided, high-performance acrylic adhesive tape is the optimal solution for permanent windtight and driving-rain proof sealing of window and door frames in solid construction on the outside*. The tape can also be used to seal the Base Joint between slab and sheathing without the use of a primer. Is has a felt-like texture, making application easy on the hands; this feature also aids in creating a seamless air and water barrier when applied to itself or WRB's like Majvest.

SIGA Fentrim 430 Grey comes available in various widths which you can find here:  6" / 9" For a pre-folded version of this tape, try Fentrim 230.
