Product Information

Full details

The PolyX Rafter Bar (Intermediate) is designed for professional builders and DIY enthusiasts constructing self-support roofing systems for conservatories or patio covers. Its primary benefit is the ability to securely join and support two polycarbonate sheets while maintaining a weatherproof seal. A key caveat is that this bar is specifically intended for intermediate positions; you will need specialized edge or wall bars to complete the perimeter of your roof structure.

FAQs

Can I use this bar for glass roofing?

No, this product is specifically designed for polycarbonate sheets between 16mm and 35mm.

Does this bar require additional rafters underneath?

No, this is a self-support bar designed to be fixed to the wall plate and eaves beam.

What is the maximum span this bar can support?

Can I use this as an edge bar?

Troubleshooting

The cap will not snap into the base.

Pros and Cons

Pros

  • Supports a wide range of polycarbonate thicknesses (16mm-35mm)
  • High load-bearing capacity for spans up to 6 metres
  • Easy snap-fit installation saves significant labor time
  • Provides a clean, professional finish with included end caps

Cons

  • Not suitable for use as an edge or wall-termination bar
  • Requires precise measurement before fixing to wall plates and eaves beams
  • Does not include mounting screws for the base

Setup, Compatibility & Care

Ensure that your support structure (wall plate and eaves beam) is perfectly level and square before installing the bars. To install:

  1. Mark the positions for the rafters on the wall plate and eaves beam.
  2. Fix the aluminium base of the PolyX bar to the support structure using appropriate fasteners.
  3. Position your polycarbonate sheets over the neoprene gaskets on the base.
  4. Snap the top capping into the base, ensuring an even click along the entire length.
  5. Attach the end cap to the lower end of the bar.

For maintenance, avoid using harsh chemicals or abrasive sponges when cleaning the white finish; warm, soapy water and a soft cloth are sufficient. Inspect the gaskets annually to ensure they remain flexible and securely seated.
