An essential part of any glass or polycarbonate roofing system, glazing bars are used to build conservatories, greenhouses, and carports.
These play a key role for many structures by securing glazing panes in place and minimising leakages. You can choose from materials such as aluminium glazing bars or plastic glazing bars (PVC) in order to achieve your desired finish.

What are glazing bars?
Glazing bars are sturdy, rigid bars designed to connect two separate panes together. You can find glazing bars for glass or polycarbonate roofing sheets, depending on your preference of glazed pane to construct your structure from.
These can be secured to the exterior of a building using a glazing wall bar or attached to a free-standing structure by screwing into the frame itself. This freedom allows you to construct weatherproof roofing for a variety of purposes, such as on treehouses or pergolas.
What do glazing bars do?
Glazing bars for polycarbonate roofs are typically used as a way of adding strength to the roofing and connecting up all the individual glazing panes. You’ll see the top section of the bar sitting between each pane, providing additional weatherproofing together with the glazing panes themselves.
The undersection is what holds the glazing bar to the glazing pane and forms a strong joint between each pane it's connected to. This tight seal is what also prevents leaks from rainwater or other precipitation from coming through to affect whatever is sitting beneath the structure.
Types of glazing bar
You’ll find two main types of glazing bar which are widely available – PVC plastic glazing bars or aluminium glazing bars. There are different benefits to using each type, depending on what sort of project you’re working on.
- Aluminium glazing bar
Offering strength and stability to outdoor structures, aluminium glazing bars are great options for securing glazing panes and providing a professional finish. These include both the ALUKAP-XR glazing bar and ALUKAP-SS glazing bar ranges, both of which are screw-down glazing bars.
ALUKAP-SS offers aluminium self-supporting glazing bars which offer a low-weight, high-strength integrated solution for your roofing system. Each component of the ALUKAP-SS range is aluminium powder coated for durability and comes in a range of colour options. It is compatible with any thickness of glass pane or polycarbonate roofing pane, giving flexibility within your designs.
ALUKAP-XR products include aluminium glazing bars which are part of a world-renowned glazing system. It is designed to secure glazing panes to hardwood, steel, or any other framework without the need for plastic end caps. With concealed fixings, great weather resistance and aluminium components as well, all you need to do is choose the colour option which suits your structure best.
- PVC glazing bar
Plastic glazing bars are typically made from polyvinyl chloride (PVC), an incredibly versatile polymer offering high durability without excessive weight. It can also be easily manipulated if elements need cutting down to size, such as wall bars for mounting your glazing panes.
Snapa glazing bars are a specialised form of plastic snap-down glazing bars. Their design allows them to simply ‘snap’ together by pressing the two sections together to securely join roofing sheets. It can act as a low-cost, low-maintenance solution for smaller DIY projects without requiring lots of additional tools for roofing construction.
How to fit glazing bars
Fitting polycarbonate glazing bars is a relatively simple process – provided you have the right know-how and tools. Depending on the type of glazing bar you’re using, you may need additional tools or support to help you.
Snapa glazing bars can simply push together, while other forms may require tightening screws to create a tight joint. The exact method for fitting will vary depending on the type of glazing bar you choose to use, but you can find exact instructions on fitting glazing bars for each product we offer.
