Uses of The Sunwood 50mm wide Rafter Bar

The 50mm wide Sunwood Aluminium Capped Glazing bars are perfectly suited for use in all glass roofs. This is the case for single skinned glass to double glazed units. They are also suited to other roofing sheets. This includes solid polycarbonate and all thicknesses of multi-wall polycarbonate. Visually the bar is stylish and has a sleek low profile. It also has neat rounded screw concealment caps. This makes it a perfect choice for high end, high quality roofs. A very popular choice for timber conservatory roofs. This timber rafter bar is perfect for orangeries and atriums. This screw down rafter glazing bar is also an excellent choice if you want to refurbish or waterproof an existing wooden conservatory roof.


These aluminium capped rafter bars are available in two widths of 50mm and 60mm. Choose the best width to suit the width of your wooden rafters. Both are suitable for all glazing thicknesses. The screw down design gives you a robust solution ideal for use in coastal or other exposed locations. Available in white or brown as standard. The bars can be powder coated to other RAL shades at additional cost.


These rafter bars are very easy to fit. They also come complete with all of the gaskets you will require. Also includes stainless steel screws. To install simply sit the base gasket straight onto your timber rafter. Then your chosen glazing sits on this. Next the aluminium top cap is firmly screwed down using the central groove as a guide. This ensures a good central fixing through to your rafter. The top cap itself has two gaskets that sit atop the glazing giving a watertight seal. Finally the screw concealment profile is then ‘clipped in.’ This will complete the smooth, sleek look.
