Key benefits Reduces incoming noise, drafts and dust for a quieter, cleaner indoor environment. Improves comfort and energy efficiency by sealing gaps between window and frame. Durable, flexible construction resists repeated compression and maintains a long service life. What’s included 1 roll, 15 meters total length. Compatibility and size Designed to seal window gaps from 4 mm to 10 mm. Please measure the gap width before purchasing to ensure a proper fit. Material and performance Made from flexible, durable silicone that withstands repeated compression and returns to shape. The strip forms a tight barrier that blocks airflow and dust while absorbing part of the sound waves to reduce noise transmission. Special profile reduces pressure between the window and frame when closing, cutting down on slamming and closing noise. Why this works for you Solves common problems: blocks drafts, keeps dust out, reduces street and closing noise, and improves indoor comfort. Stands out for both material resilience (silicone) and a design that combines sealing and sound damping in one simple strip. Easy installation Cut to length, then press into place along the window frame gap. No special tools required. Quick to install for instant improvement in sealing and noise reduction.
