CertainTeed Vinyl Siding Installation Guide

Starting on the right side of the wall, hook the bottom locking
leg of the panel into the starter strip and slide the panel into the
cornerpost or receiving channel. Leave 1/4" space between the
panel and the corner for expansion. If you are planning to install
the Mitered Cornerpost, space the panel 3" from the corner.
Fasten the panel to the wall by first nailing through the round
center hole in the nailing hem at the top of the panel. Continue
nailing the panel with 5 nails: one in the right-end nail slot and one
at each of the QuickReference
™
Nail Mark Indicators. Leave 1/8"
to 1/16" between the nail heads and the panel to allow freedom of
movement during normal expansion and contraction.
Install the next panel by positioning it below the starter strip and
next to the first panel. Push in and up to lock the panel into the
starter strip and the side tabs of the first panel. Space the second
panel according to the panel temperature at the corresponding
temperature indicator lines.
Nail the panel into position starting with the round center hole and
then placing the next nail in the right-end nail slot (which overlaps
the previous panel’s left-end slot) so that the nail goes through
both panels’ nail slots simultaneously. Continue nailing the rest
of the panel as described earlier.
Continue to install the remaining panels of the first course as
described earlier.
When a window or doorway breaks a course, continue the
application as if the opening were not there.
Second course
Cut off the right side of the D7 shingle at indicator “B,”
which is located above the nail slots. Cut straight through
the panel. Drill a 3/16" hole in the center of the nail hem and nail
the siding through this hole to control the direction of expansion
and contraction. Another option is to nail each end of a nail slot
located at the center of the panel.
Starting on the right side of the wall, hook the bottom locking leg
of the panel into the previous course and slide the panel into the
cornerpost or receiving channel. Leave 1/4" space between the
panel and the corner for expansion.
Set the spacing of the remaining panels using the
PanelThermometer and temperature indicator lines.
Continue to stagger the panel courses, alternating each time to
ensure a random shingle pattern up the wall.
Installing under a window or opening
Install Cedar Impressions undersill trim. Cut the panel to fit under
the window. Drill a 3/16" hole in the upper center of the panel.
Using a snap lock punch, raise tab faces on the outside of the
panel 1/4" from the trimmed edge, 6" apart. Lock the panel into
the previous course, and center nail the siding through the 3/16"
hole drilled earlier. (Center nailing controls the direction of the
panel’s expansion and contraction.) Lock the panel into place.

PRO TIP: When installing Cedar Impressions
over foam insulation, extra care needs to be
taken to verify that adequate space is left
between all nail heads and the panel.
