About this range & buying advice

Polycarbonate Roof Glazing Bars

These polycarbonate glazing bars are suitable for 10mm, 16mm, and 25mm Polycarbonate Roof Bars. There is also a heavy-duty bar that can be used with 25mm polycarbonate sheets. These bars are ideal for a wide range of applications, from bike sheds to warehouses.

Installation

Measure and cut the polycarbonate sheet to length, allowing an extension of approximately 50mm to overhang the gutter. Cut the aluminium base section and the uPVC top section to the same length as the sheet.

Drill holes to suit a 5mm wood screw in the centre of the aluminium base between the toothed legs. The holes should be 100mm from each end at no greater than 500mm intervals.

Screw aluminium bases to rafters using wood screws.

Lay the sheets on the rafters, starting at one end. When all sheets are in position, remove the protective film and fit the uPVC top section by pushing the legs into the slots provided in the aluminium base. Push firmly home to ensure an adequate seal.

Fit endcaps to uPVC top capping. Fit the end closure onto the end of the sheet.
