Setup, Compatibility & Care
To install, ensure your timber rafters are clean and level. It is recommended to pre-drill a hole in the polycarbonate sheet that is slightly larger than the screw shank to allow for thermal expansion. Once the sheet is positioned, drive the fixing button through the sheet and into the timber until the cap is snug against the surface. Do not overtighten, as this can compress the PVC housing excessively. For maintenance, check the buttons annually to ensure the caps remain secure and that no debris has caused the seals to shift. If a cap becomes loose, simply ensure it is snapped firmly back into its housing.
