✔ Maintains elasticity over time
✔ Suitable for outdoor environments
Problems with Low-Quality Washers
Low-quality washers may:
- Harden over time
- Crack under UV exposure
- Lose sealing performance
Result: Roof leakage
Applications
EPDM bonded washers are widely used in:
- Roofing screws
- Cladding systems
- Outdoor steel structures
Conclusion
A high-quality EPDM washer is essential for long-term roofing performance. It ensures reliable sealing and protects the structure from water damage.
