Nylon Fixing Buttons

Fixing Buttons are used to give additional fixing strength, particularly where wind loading is a consideration. The 50mm wide button which is designed to secure multiwall polycarbonate sheet to timber supports such as rafters or purlins is also used when the installer glazes at greater than the recommend glazing widths for the thickness of multiwall polycarbonate

How they work

The fixing buttons are screwed through pre-drilled holes in the sheet into the rafter or purlin, holes should be drilled oversize by 3mm. The sheet should be drilled before fitting to allow dirt, dust and swarf to be removed from the flutes.

The foam washer should be fitted between the button and the sheet as natural thermal expansion will mean the sheet will move when fitted. A 50mm, number 12 pan headed slotted screw should be used to secure the button. The screw is protected by a cover cap.

Fixing buttons should be fitted at 300mm intervals.

NOTE:

Although we supply fixing buttons, it is not a method of securing polycarbonate to a structure we recommend.

Leaking may eventually occur through the fixing button and the hole drilled in the polycarbonate, we would always prefer you to glaze to our recommended widths based on the thickness of the sheet using a suitable Twinfix glazing system.
