Timber 14X90 26mm washer (EZ Glaze) 50 Pack

When installing the 3mm glass-like EZ GLAZE system, the 90mm length is essential for projects involving deeper purlins or when a more substantial structural bite is required to counteract high wind uplift. The 14-gauge thickness ensures the screw remains rigid and resists shearing, providing a robust anchor for your roofing sheets.

The critical component for any EZ GLAZE installation is the integrated 26mm EPDM-backed washer. Polycarbonate panels are subject to significant thermal expansion and contraction; a standard small-head screw would likely cause the sheet to crack or allow water to seep through the fixing hole. This oversized 26mm washer provides a wide surface area to distribute pressure across the crest of the corrugation. The high-grade EPDM rubber gasket creates a permanent, watertight seal that moves with the panel, ensuring the structure remains leak-free and rattle-proof regardless of the British weather.

Key Features and Benefits

• Extended Reach for Crest Fixing: The 90mm length is ideal for penetrating the high profile of EZ GLAZE sheets while maintaining deep pull-out resistance in timber.

• Heavy-Duty Timber Thread: Designed to bite firmly into treated softwoods and hardwoods without stripping the wood grain.

• Superior Load Distribution: The 26mm washer prevents the “pull-through” effect during storms and protects the polycarbonate from stress-cracking.

• EPDM Compression Seal: Provides a UV-stabilised, flexible barrier that blocks rain, dust, and draughts at the puncture point.

• Corrosion Protection: Treated with a high-quality coating to prevent rust streaks and maintain the clean aesthetic of your clear roofing.
