Frequently Asked Questions

1. What is a solid polycarbonate locking roofing system?

It is a complete roofing system consisting of 4mm solid polycarbonate panels and dedicated aluminium locking profiles. The formed edges of the panels fit into the aluminium joiners, creating a clean, glass-like roof without screws penetrating the polycarbonate.

2. Is it suitable for pergola roofing?

Yes. The system is suitable for pergolas, patios, awnings, carports, skylights and other covered outdoor areas. It can be installed on timber, steel or aluminium frames, provided the structure, roof pitch and rafter spacing are suitable.

3. Can the panels be cut to length?

Yes. The panels can be cut to your required length. Standard online lengths range from 1.8m to 6m.

4. Can the panel width be cut?

The standard locking panels are designed for fixed 600mm or 800mm system widths and should normally not be cut down.

If the final panel must be narrower to fit the remaining roof width, it can be cut and finished with an aluminium H-joiner and rubber gaskets.

5. What rafter spacing is required?

Set the rafters at either 600mm or 800mm centres, depending on the selected system.

Install one panel and one aluminium joiner at a time. Do not install all the joiners first, as the panel width may vary slightly. Allow approximately 2–3mm tolerance for minor manufacturing and construction variations.

The supporting structure must also meet the wind and load requirements of your individual project.

6. What minimum roof pitch is required?

We recommend a minimum roof pitch of 5 degrees to provide effective water drainage and system self cleaning.

7. Does the system allow for thermal expansion?

Yes. The aluminium profiles secure the panels without screws penetrating the polycarbonate, allowing the sheets to expand and contract with temperature changes.

8. Is clear or tinted grey better for my pergola?

Choose clear if maintaining maximum natural light and a glass-like appearance is your main priority.

Choose tinted grey if you prefer reduced glare and solar heat while still allowing natural light into the covered area.

9. Should I Choose the Solid Polycarbonate Locking System or Flat Polycarbonate Sheets with Aluminium H-Joiners?

Choose the Solid Polycarbonate Locking System when building a new pergola or roofing structure from scratch. The supporting frame must be builded to suit.

Choose flat polycarbonate sheets when covering an existing frame or replacing the roof on an older pergola. The flat polycarbonate sheets can be cut to suit the existing rafter spacing, making this system more flexible for non-standard dimensions.

10. Can the system be curved?

Yes, the system can be used for some curved-roof applications. The polycarbonate panels can cold-bend within the permitted minimum radius, while the aluminium joiners must be professionally rolled to match the curve.

Please provide your roof width, rise and radius so we can confirm suitability before ordering.

11. What components are included?

The standard system includes:

• One 4mm solid polycarbonate panel

• One aluminium joiner set, consisting of a base profile, middle locking joiner and top capping

• End cap and screws for end cap
  

The linear-metre price includes one panel and one complete joiner set. An additional aluminium joiner is required to finish the outside edge of the final panel and is sold separately.

12. Can you deliver long panels Australia-wide?

Yes, Australia-wide delivery is available.

Residential deliveries may need to be collected from the nearest freight depot, particularly when the carrier cannot safely unload long materials at the property. Contact us for a freight quote before ordering.

13. Is professional installation available in Melbourne?

Yes. Professional installation and on-site checking are available in Melbourne.
