Product Information

Full details

The PolyX PVC Capped Timber Supported Rafter Bar is an ideal solution for DIY enthusiasts and professional contractors looking to install polycarbonate roofing sheets between 10mm and 25mm in thickness. This system offers a reliable, weather-resistant seal for conservatories, carports, and lean-tos by utilizing a robust two-part design. While it provides excellent structural support and a clean finish, users must ensure their underlying timber or metal rafters are level and structurally sound before installation to achieve a proper fit.

Extended Product Information

FAQs

Can this be used with glass roofing?

This product is specifically designed for polycarbonate sheets. It is not recommended for use with glass.

Does it come with fixing screws?

No, screws are not included as the required fastener type depends on the material of your rafters (timber or metal).

Can I join two bars together to make a longer run?

Yes, you can butt join the bars, but ensure the joints are properly sealed with a suitable exterior-grade silicone to prevent leaks.

What tools do I need for installation?

You will need a drill for fixing, a fine-toothed hacksaw for cutting the profiles, and a measuring tape.

Is the PVC cap UV stable?

Yes, the PVC cap is designed for outdoor use and is resistant to standard UV degradation.

Troubleshooting

PVC cap is difficult to snap into place

Check that no debris is trapped in the base channel and ensure the polycarbonate sheet is not overhanging the channel edge.

Roofing sheet rattles in the wind

Ensure the top cap is fully engaged and that the thickness of the polycarbonate sheet is within the 10-25mm compatibility range.

Pros and Cons

Pros

Durable aluminium base provides solid structural integrity
Snap-on PVC cap hides fixings for a neat appearance
Compatible with a wide range of common polycarbonate thicknesses
Easy to cut to specific lengths during installation

Cons

Requires pre-existing rafters for installation
PVC caps may become brittle after prolonged UV exposure over many years
Requires precise measurement of rafters to ensure even spacing

Setup, Compatibility & Care

To install, ensure your supporting rafters are clear of debris and perfectly aligned. Cut the aluminium base and PVC cap to the required length using a fine-toothed hacksaw. Fix the base to the timber rafter using screws spaced at roughly 300mm intervals. Position your sheets, then apply light pressure to snap the PVC top cap into the base. For care, keep the system free from heavy debris buildup. Use a mild soap and water solution to clean the PVC surfaces; avoid abrasive chemicals or solvents that could damage the plastic coating. Periodically check that screws are tight and the PVC cap remains fully seated in the base.
