What Is a Wall Glazing Bar?

A wall glazing bar is a specialist roofing profile designed for installations where the edge of a polycarbonate roof meets an adjoining vertical wall.

Unlike an intermediate glazing bar, which joins two adjacent polycarbonate sheets, or a gable glazing bar, which finishes an exposed outer roof edge, a wall glazing bar incorporates a raised vertical upstand.

The SupaClear CAP-X 50mm Wall Glazing Bar features a 70mm upstand that allows the glazing profile to be incorporated into a suitable weatherproof wall junction.

This is particularly useful for lean-to roofs, conservatories and canopies where the roofing structure runs alongside an existing building.

The aluminium profile is secured directly to a supporting timber rafter using concealed screw-down fixings, while the rubber glazing gasket helps maintain a secure seal against the polycarbonate sheet.

When combined with an appropriate flashing or sealing system, the wall glazing bar helps provide a neat, durable and weather-resistant roof-to-wall connection.

Suitable Applications

The SupaClear CAP-X Aluminium Wall Glazing Bar is suitable for a variety of domestic and commercial polycarbonate roofing projects, including:

• Lean-to roofs and extensions
• Conservatory roofs
• Wall-mounted carports
• Attached garden pergolas
• Patio covers and verandas
• Entrance canopies
• Covered walkways
• Timber-framed polycarbonate roof structures
• Other pitched glazing installations adjoining a vertical wall

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

Technical Specifications

How Does the SupaClear CAP-X Wall Glazing Bar Work?

The CAP-X Wall Glazing Bar secures the edge of a polycarbonate roofing sheet to a supporting timber rafter while providing a raised aluminium upstand for forming a suitable weatherproof junction against an adjoining wall.

1. Position the Polycarbonate Roofing Sheet

Install the polycarbonate roofing sheet onto the supporting timber roof structure, ensuring the sheet is correctly positioned and suitable allowances have been made for thermal expansion.

2. Position the Wall Glazing Bar

Place the CAP-X Wall Glazing Bar over the edge of the polycarbonate sheet, with the 70mm vertical upstand positioned against the adjoining wall.

Ensure the rubber glazing gasket sits evenly against the upper surface of the polycarbonate sheet.

3. Secure the Glazing Bar

Fix the aluminium glazing bar through its concealed central fixing channel into the supporting timber rafter using suitable screws.

Tighten the fixings in accordance with the installation instructions, ensuring the glazing gasket forms an effective seal without excessive compression.

4. Fit the Concealed Fixing Cover

Once the glazing bar has been secured, fit the snap-fit aluminium cover into the central fixing channel to conceal the screw heads and create a clean, professional appearance.

5. Weatherproof the Wall Junction

Complete the roof-to-wall junction using an appropriate flashing or compatible weatherproof sealing system.

The 70mm vertical upstand provides a surface against which a suitable flashing or sealing detail can be formed. The correct method will depend on the wall construction, roof pitch and installation requirements.

Always follow the relevant glazing system and flashing manufacturer’s installation instructions.

Wall vs Intermediate vs Gable Glazing Bars

Choosing the correct glazing bar is essential for creating a secure and weather-resistant polycarbonate roof.

Wall Glazing Bar

A wall glazing bar is used where the edge of a polycarbonate roof meets an adjoining vertical wall. Its raised upstand allows an appropriate weatherproof wall junction to be formed.

Intermediate Glazing Bar

An intermediate glazing bar joins two adjoining polycarbonate roofing sheets along a supporting timber rafter. It secures both sheet edges and helps provide a weather-resistant joint.

Gable Glazing Bar

A gable glazing bar is installed along the exposed outer edge of a polycarbonate roof. Its vertical downstand covers the outside face of the supporting timber rafter, providing a neat and professional edge finish.

The SupaClear CAP-X glazing system includes complementary profiles designed for different positions across a polycarbonate roofing installation.

Why Choose SupaClear CAP-X Aluminium Wall Glazing Bars?

The SupaClear CAP-X Aluminium Wall Glazing Bar combines strength, durability and a professional appearance, making it an excellent choice for polycarbonate roofing installations adjoining existing walls.

Its powder-coated aluminium construction offers excellent rigidity and corrosion resistance, while the concealed fixing system creates a cleaner finish than conventional exposed screw-down profiles.

The integrated rubber glazing gaskets help provide reliable contact between the glazing bar and polycarbonate sheet, while the 70mm vertical upstand accommodates a suitable weatherproof roof-to-wall junction.

When combined with compatible SupaClear Polycarbonate Roofing Sheets, the CAP-X range provides a coordinated roofing solution suitable for both DIY and professional installations.
