Solid Polycarbonate Locking Roofing System

The Excelite innovative Solid Polycarbonate Locking Roofing System using W600mm and W800mm flat Solid polycarbonate standing edge sheeting, Cliplock with aluminum glazing bars. This polycarbonate roofing system is an ideal choice for those seeking the appearance of a glass pergola.

This Architectural Roofing System not only provides a transparent glass-like look but also offers several key advantages

• Virtually Unbreakable, 250 times stronger than glass
• 100% Water tight
• Block 99% Harmful UV
• More Rigid than same thickness polycarbonate flat sheet
• Hails proof
• Easy to install

Excelite Polycarbonate Locking System features standing seam edges that sit atop an aluminum joiner, creating an optimal blend of transparency and strength. This system is an excellent choice for architectural daylight applications, and allowing you to enjoy outdoor living without concerns about rain and hail.

Importantly, Excelite Polycarbonate Locking roofing panels are completely leakproof and offer exceptional impact resistance.

Solid Polycarbonate Locking System vs Polycarbonate Sheet with Aluminium H Joiner

Choosing the right roofing system is essential for durability, waterproofing, and ease of installation. Below is a clear comparison between the Solid Polycarbonate Locking System and the Flat polycarbonate roof Sheet with Aluminium H Joiner to help you make the right decision.

1. System Design & Flexibility

Solid Polycarbonate Locking System

• Fixed panel widths: 600mm and 800mm (795mm centre-to-centre)

• Width cannot be adjusted

• Length can be cut to size

• Supplied with a dedicated aluminium locking joiner

• Designed as a complete, integrated system

Flat Polycarbonate Sheet + Aluminium H Joiner

• Flat Polycarbonate sheets (or roll) 

• Can be cut to suit both width and length

• Installed using aluminium H joiners and rubber gaskets

• Ideal for custom or irregular rafter spacing

2. Joining Method & Waterproofing

Solid Polycarbonate Locking System

• Panels feature standing edges on both sides

• Aluminium joiner overlaps and locks onto panel edges

• Creates a very rigid, highly secure, and watertight connection

• Excellent performance in heavy rain and wind

• No additional battens required for spans up to 800mm

✅ More rigid and more watertight than traditional systems

Polycarbonate Sheet + Aluminium H Joiner

• Sheets are joined using H joiners with rubber seals

• Rubber acts as a gasket to prevent water ingress

• Waterproof, but less rigid than a locking system

• If the span exceeds 800mm, additional battens or supports are required

3. Structural Performance

4. Pricing & Cost Efficiency

• Both systems are similarly priced overall （Same 4mm thickness)

• Solid Locking System

  • Price includes the aluminium joiner

  • Panels are cut to length → minimal waste

• Polycarbonate Sheet + H Joiner

  • Sheets and joiners are priced separately

  • Sheets must be cut to size → possible width and length wastage

  • Wastage can increase overall project cost

5. Which System Should You Choose?

✅ Choose Solid Polycarbonate Locking System if:

• You haven’t installed rafters yet, You can build to suit
  

• You want a clean, and professional finish

• Your rafter spacing can be designed to 600mm or 800mm
  

✅ Choose Polycarbonate Sheet + Aluminium H Joiner if:

• You are replacing an existing roof

• Rafters are already installed and not spaced at 600mm or 800mm

• You need flexibility to cut sheets to suit

• You are covering an existing pergola

Summary

Both systems are reliable and waterproof, but they serve different needs.
The Solid Polycarbonate Locking System offers a stronger, cleaner, and more watertight solution, while the Polycarbonate Sheet with Aluminium H Joiner provides greater flexibility for existing structures.

If you’re unsure which system suits your project, our team is happy to help you choose the best solution.
