When installing an Axgard or glass roof it is essential to have the correct glass glazing bars to properly secure your glazing. There are two main types of glazing bars for glass roofs: Self supporting and rafter supporting. Both types of glass glazing bar are manufactured from aluminium for a high-quality finish and long life span. This glazing bar selection is also suitable for Solid Glazing Sheets like Axgard.
Whether you use self supporting or rafter supporting glazing bars for your glass roof as both types work with any thickness of glass! Common projects include using aluminium glazing bars for 6mm when building a canopy or 4mm glass for a gazebo roof.
Self Supporting Glazing Bars
Using self supporting aluminium glazing bars for a glass roof removes the need for installing timber rafters and increases the lifespan significantly. Aluminium does not rot as timber does over time. What’s more, with little additional cost a self supporting glazing bar can save you money. Choose the Low span self supporting glazing bars for spans up to 3.4m* and for longer spans up to 5.6m* choose our High Span self supporting glazing bars.
Rafter Supported Glazing Bars
Rafter Glazing Bars are designed with all the same features as self supporting but without the base beam. This means they are often used for conservatory roof glazing bars when installing glass. The Alukap-XR Glazing bar range includes a wide variety of components including ridge bars, hip bars and more to suit all designs of glass roofs.
As aluminium glazing bars for glass roofs can be installed with any thickness of glazing they are also great for installing solid polycarbonate. If you want to remove the shatter risk of glass then our Axgard Solid Polycarbonate Sheets are a greater shatterproof option.
*Spanning capabilities are dependent on a wide range of factors such as location, exposure, regional loading requirements, glazing type and more so we cannot guarantee any results will be achieved. If you are unsure, please consult with a structural engineer.

Any thickness! Market-leading glazing bar brands, like the Alukap-SS range, work with any thickness of glass or glazing. This gives scope for a wide range of glass types from 6mm solid through to triple glazing.
It depends entirely on your roof type. Self supporting glazing bars offer a greater lifespan and are best for lean-to or carport style roofs. On the other hand, rafter supporting glass glazing bars work with a wider range of roofs due to the extra components available such as hip bars, ridge bars and caps for timber roof lanterns.
Glazing bars that have been designed for glass are always aluminium to ensure they have the strength to properly secure the glazing. Compared with other roofing materials, such as polycarbonate, glass has a lot greater weight so aluminium glazing bars are the only type of bars that are robust enough to deal with this.
