Rafter Glazing Bars

Rafter Glazing Bars

Rafter Glazing bars sit on wooden rafters for support and are available for polycarbonate and glass roofs. We have a wide range of rafter bars to suit your project.

PVC Capped rafter glazing bars are strong, lightweight and easy to fit. These are often referred to as snap down bars as the aluminium base screws down into your rafter and the PVC top cap then snaps down into it to hold your sheet in place. We have two types of snap down rafter bars.  The standard range is suitable for 10mm, 16mm and 25mm Multiwall Polycarbonate Sheets. The professional pvc capped rafter glazing bars accommodate 25mm, 32mm and 35mm sheets. Both ranges of snap down glazing bars are a cost effective solution for a wide number of applications. PVC capped rafter bars are not suitable for glass roofs. Here a screw down bar is needed. We have PVC rafter bars available in White, Brown and Anthracite grey.

Our range of Aluminium Capped glazing bars includes the 50mm wide and 60mm wide Sunwood bars. These rafter bars are robust and maintenance free. The Sunwood screw down rafter bars accommodate all thicknesses of Polycarbonate Sheets, plastic sheets and all thicknesses of glass. Rubber base gaskets sit on your wooden rafters and the top cap is screwed down to hold your sheets securely in place. They have a low profile finish with neat screw concealment capping. Highly adaptable, powder coated aluminium rafter bars are paticularly suitable for glass roofs and for where extreme variations in temperature are experienced. Aluminium capped bars are also recommended in areas which are exposed to higher winds e.g coastal areas.

See our Guide to what you need for a Timber supported roof. If you require components for a shaped Conservatory roof including ridges, hips etc, please go to our 'Sunwood Timber Glazing' Category.
