Rafter Supported Glazing Bars

What is a glazing bar?

Glazing bars are essential to roofing systems. Glazing bar kits usually consist of bars and accessories used for fitting and joining material together in a roofing application. Glazing bars are also a cost-effective way to fuse polycarbonate sheets needed for roofing.
We have high-quality rafter supported glazing bars made to ensure tight glazing and easy installation. Glazing bars can be affixed on polycarbonate sheets of timber conservatories, pergolas, lean-to roofs, and other outdoor structures.

The appeal of our rafter supported glazing bars in a nutshell

Timber conservatories, pergolas, carports, lean to roofs, and more can be installed with the use of rafter supported glazing bars. Those bars that we offer can be used with 10mm, 16mm, and 25mm polycarbonate sheets to securely protect people from falling rain and other adverse weather.

This is not only because the bars are good for ensuring tight glazing, but also due to the extremely strong aluminium from which the bars are made. Putting the bars in place is easy, too. Each bar's base section is attached to timber rafters; then, the aluminium base can be snapped into a durable but low maintenance PVCu top cap, leading the EPDM rubber gaskets to seal.
 

How else you can benefit from using these bars

That seal will be weather-tight. Hence, you will be able to enjoy sitting in the building for which these bars have been installed and not have to fret about the possibility of rain, snow, or other, similarly bad weather affecting your enjoyment. Instead, you could just sit and watch the beautiful effect of that weather outside - all while you enjoy the warmth of the building's interior.

We stock other products that you can utilise during the installation of rafter supported glazing bars. However, these bars should only really be put in place by someone who is experienced in or knowledgeable about doing so - like a DIY expert or tradesperson. Thus, you might need external assistance with having those bars secured.

How to Install Glazing Bars?

The first step to basic installation is to ensure that you have the correct framework in place. The measurements should be precise. The minimum width of the rafter, joist, or purling should match the width of the glazing bar.

Next, drill in the centre of the glazing bars between the teeth. Our recommendation is to drill at a maximum interval of 400mm and around 75mm from both ends.

Position the sheets and push them up against the teeth to make sure that the polycarbonate is secure.
Push the plastic snap into place firmly for a tight finish
