The PolyX PVC Capped Rafter Bar is an essential structural component designed for DIY enthusiasts and professional contractors tasked with installing polycarbonate roof sheets. It provides a robust, weather-resistant mounting solution for glazing projects, ensuring panels are held securely while preventing moisture ingress. While it offers excellent durability and a clean finish, users should note that it requires a sturdy timber or metal framework for proper installation and is specifically engineered for sheets between 10mm and 25mm in thickness.

This product is specifically designed for polycarbonate sheets and is not recommended for heavy glass glazing.
The base package includes the aluminium base and PVC cap; end caps are usually sold separately or as part of a finishing kit.
Yes, the PVC cap is designed to withstand exposure to sunlight, though occasional cleaning helps maintain the finish.
Rafter spacing should be determined by the width of your polycarbonate sheets and the manufacturer's load-bearing recommendations.
No, the aluminium base is rigid and should not be bent; it is intended for flat or pitched roof installations only.
Check that the aluminium base is not bowed due to overtightening screws and ensure there is no debris trapped in the locking channels.
Verify that your polycarbonate sheet falls within the 10mm-25mm range and that the base is centered correctly between the sheets.
To install, first measure and cut your base bar and PVC cap to the required length using a fine-tooth hacksaw. Secure the aluminium base to your rafters using appropriate fasteners, ensuring the screw heads sit flush. Lay your polycarbonate sheets on either side of the base, then snap the PVC cap into place starting from one end and moving toward the other.
Compatibility: Works with polycarbonate sheets between 10mm and 25mm. Compatible with both timber and metal rafter frameworks.
Care: To maintain the appearance and structural integrity, clean the PVC surface periodically using a soft cloth and a mild soap solution. Avoid abrasive sponges or harsh chemical solvents that could degrade the finish.
