B5 Fibre-cement corrugated sheet is a replacement for the standard 3 inch profile corrugated sheet.
The B5 metric corrugation profile is a more modern profile than the traditional 3 inch profile so can be used to a lower pitch and with smaller overlaps. The sheets are approximately 40% wider, offering a better coverage per sheet. B5 is available in 12 lengths from 4′ 6″ to 10′ 6″. B5 can be used to refurbish buildings clad in 3 inch sheets utilising ‘existing purlin centres’. All existing 3 inch sheets need to be removed, it is not possible to replace individual 3 inch sheets with B5.
