Self-Support Main Bars for 24mm Glass & 25mm Polycarbonate

Heavy-Duty Structural Glazing Bars for Conservatories, Orangeries & Roofing Systems

When strength, span, and structural performance matter, standard glazing bars simply aren’t enough. Our self-support main bars are engineered to deliver exceptional load-bearing capacity without the need for additional rafters or support beams. Designed specifically for 24mm double-glazed units and 25mm polycarbonate sheets, these premium aluminium bars provide a robust, reliable solution for modern roofing and glazing systems.

Whether you're building a high-performance conservatory, a contemporary orangery, or a commercial canopy, these self-supporting glazing bars offer the strength, flexibility, and professional finish required for demanding projects.

What Are Self-Supporting Glazing Bars?

Unlike traditional glazing bars that rely on timber rafters or substructures for support, self-supporting main bars are designed to carry loads independently. This means fewer structural components are required, simplifying your build while maintaining superior strength.

Key advantages:

• No need for additional timber rafters
• Reduced installation time and labour
• Cleaner, more modern roof design
• Greater structural efficiency

By eliminating unnecessary framework, these bars allow for larger spans and more open, light-filled spaces.

Designed for 24mm Double Glazing & 25mm Polycarbonate

These glazing bars are precision-engineered to work exclusively with:

• 24mm double-glazed sealed units
• 25mm polycarbonate roofing sheets

The integrated channel system ensures a secure, accurate fit for both materials, delivering excellent alignment and long-term weatherproofing performance.

Important:

This product is only suitable for 24mm glass units or 25mm polycarbonate sheets and should not be used with other thicknesses.

Heavy-Duty Aluminium Construction

Manufactured from high-grade aluminium, these self-supporting roof bars provide outstanding strength while remaining lightweight and easy to handle.

Benefits of aluminium construction:

• High load-bearing capability
• Corrosion-resistant and long-lasting
• Lightweight for easier installation
• Structurally stable in all weather conditions

This combination of strength and practicality makes them ideal for both domestic and commercial glazing projects.

Eliminate the Need for Additional Support Beams

One of the biggest advantages of these self-support glazing bars is their ability to span without intermediate supports.

This means:

• No bulky timber rafters interrupting your design
• Faster installation with fewer components
• Reduced overall project cost
• Cleaner internal and external aesthetics

For modern builds where minimalism and open space are key, this system offers a significant advantage.

Precision-Engineered Glazing Channels

Each bar features dedicated glazing channels designed to securely hold your chosen material in place.

Engineered for performance:

• Perfect fit for 24mm sealed units
• Secure seating for 25mm polycarbonate
• Consistent pressure for effective sealing
• Reduced risk of movement or rattling

This ensures your roofing system remains stable, secure, and weather-resistant over time.

Excellent Weatherproofing Performance

A roofing system is only as good as its ability to keep the elements out. These glazing bars are designed to deliver reliable weather protection across all conditions.

Protection against:

• Heavy rain and water ingress
• Wind uplift and structural movement
• Temperature fluctuations
• Long-term environmental exposure

When installed correctly with appropriate seals, they form a robust barrier that protects your structure year-round.

Ideal for Conservatories, Orangeries & Roofing Systems

These 1500mm self-support main bars are suitable for a wide range of applications, making them a versatile choice for both residential and commercial projects.

Common uses include:

• Conservatory roofs
• Orangery roof structures
• Lean-to roofing systems
• Garden rooms and extensions
• Commercial glazing installations
• Canopies and covered walkways

Their strength and flexibility make them particularly well-suited to projects where both performance and appearance are important.

Mix Glass and Polycarbonate in One System

A major advantage of this glazing system is its ability to accommodate both glass and polycarbonate within the same structure.

Why this matters:

• Use glass where insulation and clarity are key
• Use polycarbonate where lightweight coverage is needed
• Tailor performance across different sections of the roof
• Optimise cost without compromising quality

This flexibility allows you to design smarter, more efficient roofing systems.

Simplified Installation Process

Despite their strength and capability, these bars are designed with installation efficiency in mind.

Installation benefits:

• Fewer structural components required
• Straightforward fixing to the main supports
• Reduced labour time
• Cleaner, more predictable build process

This makes them ideal for professional installers looking to streamline projects, as well as experienced DIY users tackling larger builds.
