SIGA Fentrim IS 20 (100mm)

Fentrim IS 20n(100mm) is the complete interior window and door flashing tape you've been looking for. This interior version of Fentrim has a small pre-fold to help with flashing windows on the inside. The SIGA Fentrim IS 20 has a very low perm rating because it is designed to be used on the interior, creating a fully air-tight seal. 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!

The white, single-sided, high-performance acrylic adhesive tape is the optimal solution for permanent air-tight sealing of window and door frames in solid construction on the inside. Is has a felt-like texture, making application easy on the hands; this feature also aids in creating a seamless air-barrier when applied to itself or air barriers like SIGA Majpell or SIGA Majrex. Fentrim IS 20 comes pre-folded, making application between rough opening and window easy and efficient.

Available folded in the size 75mm  (15/60mm), as well as 100mm (15/85mm).

Width: 100mm (85mm backed plus a 15mm pre-fold) Length: 82'
