Second course
Cut off the right side of the D7 shakes at indicator “B,” which is
located above the nail slots, cutting 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.
Installing over a window or opening
Cut the panel to fit over the window by measuring from the locking
tab of the previous row to the bottom of the receiving pocket.
Add 1/8" to this measurement. Turn the panel over and, using this
measurement, measure from the bottom of the return leg.
Cut the panel to this dimension. Install the cut panel by positioning
the panel over the window and into the receiving pocket. Lock the
cut panel into the previous course by pushing in and up. The cut
edge should be 1/4" below the top of the receiving pocket.
Finishing the top course
See instructions on page 65.
Installing Cedar Impressions Mitered Cornerpost
If you are planning to install Mitered Cornerposts, space the siding
panel 3" from the edge of the corner. Lock the first corner over
the siding, making sure it also locks into the starter strip.
Nail the corner through the top two nail slots.
NOTE: We recommend that your complete the first wall before
installing the cornerpost. Then install the cornerpost as you
install the courses of the second, adjacent wall.

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.
