Fixing buttons have been designed to give additional fixing strength. It is recommended that fixing buttons are used if wind loading has to be taken into consideration.
They are used to secure the multiwall sheets to timber supports. All sheets have pre-drilled holes where the fixing buttons are to be screwed through and need to be drilled oversize by 3mm.
We offer an extensive range of fixing buttons with regards to size, which you can find below:
We recommend that the included foam washer be fitted between the button and the sheet. This is to account for thermal expansion, which would move the sheet when fitted. The screw is protected by a cover cap. 300mm intervals between each fixing button is recommended.
