In addition to the frieze board treatments
described above, there are several other options
for finishing the juncture where the siding meets
the soffit.
CAULK THE SIDING/SOFFIT JOINT
A fast and economical method of finishing the
siding/soffit juncture is simply to run a bead of
quality caulk along the top edge of the siding
where it meets the soffit. A straight rip cut along

INSTALLING FRIEZE BOARDS
FRIEZE MADE FROM HARDIETRIM
®
5/4, 4/4 BOARDS
When using lap and shingle sidings, install
HardieTrim 5/4, 4/4 boards as a frieze
board before putting in the siding. Then
run courses of siding up to the frieze
board and caulk the junction of the frieze
board and siding. In a building sided with
HardiePanel siding, the frieze board is
commonly over the panel siding. If joints in
the HardieTrim 5/4, 4/4 boards frieze are
necessary for longer runs, join boards with
a bevel cut. Nail the frieze board every 16
in. using finish or siding nails.

TREATMENT OPTIONS FOR THE SIDING/SOFFIT JUNCTURE
In areas where additional insect
protection is desired, a screen may
be applied to the back side of the
panel prior to soffit installation. After
the screen type and size is selected,
cut the screen to fit so that it covers
the vent holes and overlaps the
non-vented area of the soffit by 1
in. to 2 in. Secure the screen to the
backside of the soffit panel using a
bead of construction adhesive.

INSTALL CROWN MOLDING
Crown molding is another way of finishing and sealing the soffit/siding juncture. Install
and finish the crown molding according to the manufacturer’s specifications.
OVER THE TOP OF THE SIDING WITH ‘J’ CHANNEL
Once the soffit is in place, install a vinyl “J” channel upside down with the base of the
“J” against the soffit. Then rip the final course of siding so that it fits inside the channel.
