9. FITTING BATTENS
9.1
BATTEN SETTING OUT AND FIXING
Referring to the illustrations, measure the distance between the top apex final course batten (top edge) to
the first bottom eaves course batten (top edge) and from that dimension deduct 35mm.
The result is the distance between the top batten and the first course of batten using
the top edges to measure from.
Use this distance to calculate the number and spacing of battens,
being careful to note the minimum batten gauge required (see below).
N.B Always use a chalk line to establish the gauge for
each batten course, the top edge of the batten is
mechanically fixed to the underside of the chalk line.
Fix the battens, leaving out the final top course.
Note: The installer may need to adjust the batten gauge settings
to accommodate the rafter dimensions. This is achieved by
reducing the gauge to either a 265mm or 250mm gauge
setting to assist the final position of the top course of batten.
Alternatively, set out the battens to your preferred gauge and
affix a short final batten course where the installer will have to
simply cut and shorten the top course of tiles as illustrated on
page 18.
