Products / Custom Weatherstrips

Koz İplik’s flexible manufacturing infrastructure offers tailored solutions for technical requirements that go beyond standard dimensions. We can produce all variations from our core product range (standard, finned, finned nonwoven, adhesive-backed) in custom sizes, and even combine these features in hybrid configurations.
Our Areas of Technical Flexibility:
Dimension Adaptation: Custom profile widths (4.5–12.7 mm) and heights (4–20 mm)
Combination Options: Hybrid solutions such as finned + adhesive or nonwoven + UV-resistant
Material Diversity: Adjustable PP hardness or EPDM alternatives
Color Matching: Custom colors available per RAL catalog specifications
Application Examples:
- Non-standard cross-section wooden window systems
- Narrow-space insulation for industrial roller shutters
- Special angled fin designs for the furniture industry
All of our custom-made solutions maintain the core technical properties of our standard products:
- ✓ 3,600 filaments/cm² density
- ✓ 150–160°C heat resistance
- ✓ UV stabilization
- ✓ 30–60% elongation at break
