Installation Instructions

STEP 4
INSTALL SIDING
For ease of application, vertical
installations should start at the corner
post. Partially fill the throat of the
corner post with furring strip 2" (50
mm) wide. Leave sufficient space to
install an undersill trim vertically, over
the furring, in the throat of the post.
Cut off the locking leg of the first
panel, and with a snap lock punch
perforate the edge of the panel at 12"
(300 mm) intervals. Make sure that the
punched “ears” face outwards from
the building. Lock the punched edge
of the panel into the undersill trim and
nail the vertical panel in place, through
the nail slots. Subsequent panels are
interlocked and nailed in place. The
final panel is measured and cut to size,
perforated with the snap lock punch
and snapped into the undersill trim.
Before installing any siding, measure
the width of the wall to ensure that the
last panel will fit into an undersill trim
in the corner.

VERTICAL SIDING INSTALLATION
INSTALLING VERTICAL SIDING ON MAIN WALLS
Refer to pages 4 - 6 for the accessories to be used for vertical siding
installation, and for the method in which these are cut for overlapping.
STEP 1
VERTICAL J-CHANNEL
Vertical J-channel serves as starter
strip for vertical siding. Use a
chalk line and level to ensure the
J-channel is straight and level.
Install J-channel along chalk line as
a receiver for the vinyl siding. The
J-channel should drop below the
old siding, forming a drip edge. If
a drip edge cannot be made, install
base flashing to be sure water
drains clear of the structure.
STEP 2
CORNER POSTS
The outside and inside corner posts are installed in exactly the same
way as shown in Steps 1 and 2 of the horizontal siding instructions.
The corner posts must overlap the trims at the bottom of the wall.
STEP 3
TRIM AROUND WINDOWS,
DOORS AND OTHER
OPENINGS
Install J-channel down the sides
of windows and doors or inverted
along the gable slope or top of
wall, as explained in Step 4 of the
horizontal siding instructions,
leaving a gap for expansion. Install
drip cap over windows and doors
and then install vertical J-channel,
all as illustrated. Install vertical
J-channel below windows
and doors, as illustrated.

INSTALLING VERTICAL SIDING ON GABLE ENDS
The installation of vertical siding on gable ends is very similar to any
other vertical installation, except that you start with a very small piece,
and, for a clean look, you want to have the groove of the vertical panel
in line with the peak of the gable.
Trim the perimeter of the gable with vertical J-channel (1/2"),
overlapping at joints. If horizontal siding is installed below vertical,
use Vertical Belt Line as a starter strip at the bottom of the gable.
(Ensure the starter strip is level).
