Limitations:
- This DTC sheet is for roof applications only- All batten spacings shown are for three or more equal spans.- Roof batten spacing is infuenced by support (truss) spacing or sheetingspans
- Pair of screws at connections must be in line and parallel with thesupporting member- All truss spacings (batten spans) shown are suitable for foottraffic loads to NASH Standard Part I
- Batten spans are based on the use of screws tested and specified on thisdata sheet for each support type and thickness- Maximum batten spacing may be limited by span of the cladding. It isessential that this sheet is read in conjunction with the relevant deemedto comply information for the roof sheeting adopted.
