Always pre-drill the sheets with a drill 2mm larger than the fixing screw to allow for sheet movement due to expansion and contraction of the material.
“Corri-glas” sheets should be crest fixed at every second or third corrugation at the ends, and every third or fourth corrugation on intermediate supports. Always use Zammit Roofing fixing screws and weather seals.
“Trim-glas” sheets should be crest fixed on each rib at the ends and every second rib on the intermediate supports.
Long lengths (up to 6 metres) are available, but if joining two or more sheets lengthwise, the joins should be made over a batten or purlin, with a 150mm overlap.
When fixing fibreglass sheeting always work from planks placed over structural supports.
Use a fine tooth handsaw or a power saw fitted with a masonry type cut-off blade. Support the sheet close to where you are cutting. It is good practice to wear protective goggles when cutting any material with a power tool. Zammit Roofing sheeting can be custom cut to any length on order, your supplier can arrange this if required.
Waste and sheeting off cuts should not be burned but disposed of with your household garbage or at the local waste centre.
