Fentrim F 4"
Meet the newest addition to the SIGA family. Fentrim F 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!
This 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 between slab and base joint 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.
