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.
For a pre-folded version of this tape, try Fentrim IS 2.
*This tape is not designed for use in permanently UV exposed applications.
