Product Information

Full details

The PolyX Fixing Buttons (16mm, White) are designed for DIYers and professional contractors installing polycarbonate roofing sheets on timber structures. These buttons provide a secure, watertight attachment point that prevents sheet slippage, ensuring a durable installation for long-term use. While they are highly effective for 16mm sheets, users must ensure they do not overtighten the screws to avoid damaging the polycarbonate surface.

FAQs

Are these buttons suitable for 10mm polycarbonate?

No, these are specifically engineered for 16mm polycarbonate sheets.

Can I use these on metal rafters?

These fixings are designed for use on timber rafters only.

Do I need to drill pilot holes?

Yes, it is recommended to drill a pilot hole in the polycarbonate to prevent stress cracks and allow for thermal expansion.

How many buttons come in a box?

Each box contains 10 complete button assemblies.

Can I paint these buttons to match a different roof color?

While technically possible, painting may cause the PVC material to degrade or the paint to flake off; using the provided white finish is recommended.

Troubleshooting

Sheet is moving or rattling

Ensure the screw is fully seated and the button is applying enough pressure to hold the sheet flush against the rafter.

Cap keeps popping off

Check that no debris is inside the cap rim and verify the screw head is not protruding too far.

Water leaking around the fixing

Verify that the rubber seal is correctly positioned and that the screw has not been overtightened, which can deform the seal.

Pros and Cons

Prevents thermal movement and sheet slippage
Easy to install with a standard screwdriver

Cons

Limited to 16mm thickness polycarbonate sheets
Requires careful manual tensioning to avoid overtightening
Not intended for metal purlin applications

Setup, Compatibility & Care

For optimal results, ensure your timber rafters are clean and level before beginning. Use a drill to create a pilot hole slightly larger than the screw shank to allow for natural thermal expansion of the polycarbonate. Do not overtighten the screws; the seal should be snug but not indented into the sheet surface. Periodically check the caps after extreme weather events to ensure they are seated correctly. For maintenance, a simple wipe with mild soap and water is sufficient to keep the white finish looking clean.
