 Once
the fascia board is installed, one long edge of the
soffit board cladding or soffit ventilator is fitted
into the groove cut into the rear of the fascia board
or placed on the extended lip of the cover board and
secured to rafter feet. On Titan and Leda board applications
allow an extra 10mm on the width for the board to sit
securely into the groove.
Titan Board has a stepped groove which accepts 8mm
and 10mm soffit boards. Boards should always be supported
along their length and fitted with 2 x 40mm plastic-headed
nails at 600mm centre to timber eaves hangers or noggins
for level soffit.
For an inclined soffit, fixing is to the underside
of the rafters. Soffits should always be supported along
their length at fascia wall and board junctions and
fixed at 600mm cebtres with 2 x 40mm plastic-headed
nails.
Widths should not exceed 200mm unsupported. For extra
widths soffit boards can be jointed using a longitudinal
coupling trim leaving a 5mm expansion gap for thermal
movement. When using cladding planks as soffits, running
joints should be made with open V joints and staggered.
It is recommended that runs be broken up with a centre
joint trim.
