Polycarbonate Fixing Buttons (pack of 10) for either 10mm / 16mm / 25mm Polycarbonate Sheets Polycarbonate Fixing Buttons can be used to give additional fixing strength to multiwall polycarbonate roofs, particularly where wind and/or snow loading is a concern. The polycarbonate fixing buttons are designed to secure multiwall polycarbonate sheet to timber supports such as rafters or purlins and can also be used when an installer glazes a sheet of multiwall polycarbonate at centres greater than those recommended by the manufacturers. Pack consists of 10 x buttons, 10 x foam washers, 10 x Steel Screws Polycarbonate fixing buttons should be screwed through pre-drilled holes in the multiwall polycarbonate sheet into the rafter or purlin. The sheet should be drilled before fitting to allow dirt, dust and swarf to be removed from the flutes and the holes should be drilled oversize by 3mm at 300mm intervals. Buttons should not be fitted nearer than 150mm from the edge of the sheet and should be used in addition to glazing bars, not as an alternative.
