The Sunwood Aluminium Capped Glazing bars are perfectly suited for use in all glass and polycarbonate roofs. The bars are available in widths of 50mm or 60mm dependent upon the width of your rafters. Visually the bar has a sleek low profile making it ideal for modern or traditional roof finishes. It has a neat, rounded screw concealment cap to hide your fixings making it a perfect choice for high end, high quality roofs. Perfect for timber conservatory roofs, orangeries and atriums. This screw down rafter glazing bar is equally suited to new constructions or if you would like to refurbish or waterproof an existing wooden conservatory roof.

The screw down fixing makes these bars particularly suited to costal or other windy locations where a strong fix is needed.


These aluminium capped rafter bars are available in two widths of 50mm and 60mm. Both are suitable for all glazing thicknesses. Available in white and brown as standard for use with the other elements of a Sunwood roof. They are also available in anthracite grey or mill finish in 50mm & 60mm widths (so they can be powder coated to other RAL shades) for use in lean to roofs.


Extremely easy to fit the bars come complete with all of the gaskets you will require and the screws. First sit the base gasket straight onto your timber rafter and your chosen glazing sits on top of this on either side. Screw down through the aluminium top cap between the glazing sheets using the central groove as a guide.  The top cap itself has two slide in gaskets that sit atop the glazing ensuring a watertight seal. The curved screw concealment ‘c’ profile is then ‘clipped in’ to complete the neat and smooth look.
