What Is an Intermediate Glazing Bar?

An intermediate glazing bar is used to join two adjoining polycarbonate roofing sheets along a supporting roof rafter.

Unlike an edge or gable glazing bar, which finishes the outside edge of a roof, an intermediate glazing bar is positioned between two sheets, securing both edges to the roof structure.

The SupaClear CAP-X 50mm Intermediate Glazing Bar features a central screw-down fixing system, allowing the aluminium profile to be secured directly to the timber support beneath.

Its integrated rubber gaskets help prevent water ingress while maintaining a secure connection between the polycarbonate sheets and roof structure.

Suitable Applications

The SupaClear CAP-X Intermediate Glazing Bar is suitable for a wide range of pitched polycarbonate roofing projects, including:

• Conservatory roofs
• Lean-to roofs and extensions
• Timber-framed carports
• Garden pergolas
• Patio covers and verandas
• Entrance canopies
• Covered walkways
• Domestic and commercial roof glazing

Whether installing a new polycarbonate roof or replacing an existing glazing bar system, the SupaClear CAP-X range provides a practical and professional roofing solution.

Technical Specifications

How Does the SupaClear CAP-X Glazing Bar Work?

The CAP-X Intermediate Glazing Bar secures two adjacent polycarbonate roofing sheets to a timber rafter using a concealed mechanical fixing system.

1. Position the Polycarbonate Sheets

Place the adjoining polycarbonate roofing sheets onto the supporting timber rafters, leaving the appropriate expansion gap between the sheets.

2. Position the Glazing Bar

Place the aluminium glazing bar centrally over the joint, ensuring the rubber gaskets make even contact with both sheets.

3. Secure the Glazing Bar

Fix the glazing bar through its central channel into the supporting timber rafter using suitable fixings. Tighten according to the installation instructions to achieve an effective seal without excessive compression.

4. Fit the Concealed Fixing Cover

Once secured, fit the aluminium cover into the central channel to conceal the screw heads and create a neat, professional finish.

5. Complete the Roof Installation

Install the appropriate glazing bar end caps, sheet closures and other compatible roofing accessories to complete the system.

Why Choose SupaClear CAP-X Aluminium Glazing Bars?

Aluminium glazing bars offer several advantages over basic plastic glazing profiles, particularly where durability, appearance and secure sheet retention are important.

The powder-coated aluminium construction provides strength and weather resistance, while the concealed fixing system creates a cleaner appearance than exposed screw-down alternatives.

The integrated gaskets help maintain an effective seal against rainwater, making the CAP-X range a suitable choice for exposed outdoor roofing installations.

Combined with SupaClear Polycarbonate Roofing Sheets, the CAP-X system provides a reliable solution for creating attractive, long-lasting glazed roofs.
