Pile weatherstrip is a critical component that provides sealing and insulation for aluminium and PVC door and window systems, glass balconies, insect screens, and roller shutters. Koz İplik meets Turkey’s pile weatherstrip needs with 100% domestic production, serving dealers and manufacturers as a trusted partner. This article details the technical characteristics, applications, and advantages of Koz İplik pile weatherstrips.

What Is a Pile Weatherstrip and How Does It Work?

A pile weatherstrip is a sealing tape designed to block air, water, dust, sound, and light from the external environment. Its textile-plastic construction — a rigid base with soft filaments — offers a low friction coefficient, particularly suitable for sliding doors and windows. This reduces wear between aluminium, PVC, and composite surfaces and enables smooth sliding. Koz İplik pile weatherstrips are woven from multi-filament polypropylene (PP) yarns to deliver maximum sealing performance.

Weatherstrip Usage Areas

Pile weatherstrips serve a broad range of applications and industry needs:

Aluminium Door & Window Systems: Prevent air, water and dust ingress in sliding and fixed systems.

PVC Door & Sliding Systems: Deliver smooth operation thanks to low friction.

Glass Balcony Systems: Finned pile types provide weather resistance and an aesthetic finish.

Insect Screen & Roller Shutter Systems: Block insects, dust, and wind entry.

Furniture Sector: Custom pile weatherstrips provide both aesthetic and functional sealing.

Other Uses: Tailored solutions for automotive, appliances, and industrial systems.
