Fentrim 430 Grey

Brand: SIGA

The SIGA Fentrim 430 Grey is a high-performance, pre-folded sealing tape designed for quick and precise airtight and weatherproof sealing around window and door frames. It’s suitable for both interior and exterior applications in high-performance and passive house construction.

Its strong adhesive bonds to a variety of substrates, including masonry, concrete, and timber, even in cold temperatures. The flexible, pre-folded design allows for clean corner detailing and adapts to irregular surfaces for a reliable, long-lasting seal.

SIGA Fentrim 430 grey is a fleece-backed, semi-permeable acrylic flashing tape. The robust, polyolefin (PO) carrier resists jobsite abrasions while remaining formable and pliable, even in below-freezing temperatures. Fentrim 430 grey offers superior adhesion to cured concrete, metal and wood.
