What it does Stops drafts, dust and outside noise at the bottom of doors and windows to keep rooms warmer and quieter. Seals gaps with 0.1 mm density bristles that conform to uneven thresholds for an effective weatherseal. Key features and materials Adhesive backing: advanced adhesive technology with a nanocomposite material and thickened backing for reliable stick — stays attached even in humid environments. Bristles: 0.1 mm density fibers block cold air and debris while allowing smooth door movement. Construction: integrated molding process and durable materials deliver a sturdy profile that won't break easily and is built for longterm use. Size and compatibility: supplied in a 1meter length with a cuttable design so you can trim it to fit most doors and window bottoms.
