Products / Standard Weatherstrip

Koz İplik Standard Weatherstrip is an industrial solution optimized for basic sealing in aluminum, PVC, and wood door/window systems. Woven from multi-filament polypropylene (PP) yarns, the product achieves maximum mechanical durability with a density of 3,600 filaments/cm² and a 0.70 mm base thickness. Manufactured using UV-stabilized PP granules, it resists degradation from sunlight, and with 30–60% elongation at break, it adapts to structural movements.



Its thermal properties include a softening point of 150–160°C and an 85–90% thermal recovery rate. These technical advantages ensure stable performance in temperatures from –30°C to +80°C, making it an ideal solution for vertical window systems, fixed-door installations, and shutters under light-load conditions. With moisture absorption below 0.1%, it prevents mold and bacterial growth, maintaining a hygienic environment.
