Installation Instructions

Installing Under a
Window or Opening
Install undersill trim. Cut
the panel to t under
the window. Drill a 3/16"
hole in the center of the
nail hem. 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 (gure 8).
Installing Over a Window or Opening
Cut the panel to t over the window by measuring from
the locking tab of the previous row to the bottom of the
receiving pocket (gure 9). Add 1/8" to this measurement.
Turn the panel over and, using this measurement,
measure from the bottom of the return leg (gure 10).
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
To nish the top course
of siding, attach cornice
receiver to the top of the
wall under the eave or
soft. Trim the top panel
to within 1/4" of the
cornice receiver. Using
a nail slot punch, punch nail slots 1/4" from the trimmed
edge, 16" apart. Nail off the top course and snap the
cornice molding into the cornice receiver (gure 11).
Installing Mitered Offset Cornerpost
Before applying siding and accessories, make certain
the substrate is watertight. To be properly protected
from precipitation, make sure you have properly ashed
the substrate so that it sheds water outside the siding.
The siding and accessories alone are not meant to be a
watertight barrier.
For the best appearance and easier installation, we
suggest you install the Mitered Offset Cornerpost as you
move up the wall. If you prefer, you can install Mitered
Offset Cornerposts after the siding has been installed.
1. Install the rst Cedar Impressions panel 3" from the
edge of the outside wall (gure 12).
2. Once the panel has been fastened, hook the corner “A”
over the siding, making sure the corner piece is locked
into the starter strip (gure 13).
3. Nail through the top two holes of the cornerpost.
4. Continue installing the corner pieces as you move up
the wall. Following the pattern of A, B, C, D and then
repeat (gure 14).
