How can I minimise waste?
• If the wall contains doorways or windows that are more than 1210mm wide, you can sometimes save material by starting to sheet at one edge of the opening; i.e.: if you can avoid cutting a large hole out of a sheet • To fill in heads above doorways and floor-length windows less than 1210mm wide, you can use off-cuts, rather than cut large holes out of a full sheet. This is done by cutting the off-cut back to the appropriate groove and butt-joining this to the groove of the next full sheet. NOTE WELL: The heads must be filled in as you go, otherwise you may not end up with a gap that is a full number of ‘boards’ wide. • When you have finished one wall, use the off-cut from the last sheet to start the next wall. • The tongue can be trimmed off an off-cut so that it can be butt-joined to another sheet.
