CertainTeed Vinyl Siding Installation Guide

NOTE: Cedar Impressions Half Round Shingles are installed
from left to right.
First course
Strike a level line around the house and install Cedar Impressions
Metal Starter (see illustration 1a). An alternative method of starting
Half-Rounds is to use J-channel in place of starter strip, to receive
the bottom edge of the panel (see illustration 1b). To use this
method, the rounded portion of the panel must be removed below
the locking leg to create a continuous straight edge.
NOTE: When using a J-channel as a starter, leave 1/4"
between the siding panel and pocket.
Remove 2-5/8" from the left side of the upper panel course,
leaving a 90° left side edge.
Starting on the left side of the wall, hook the bottom edge 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
inside wall of the cornerpost for expansion.
Fasten the panel to the wall by first nailing through the round
center hole of the nailing hem at the top of the panel. Then fasten
the rest of the panel by nailing through the centers of the remaining
nail slots a maximum of every 8" to 16" on center. Provide 1/8"
to 1/16" between the nail head and the panel to allow freedom of
movement during normal expansion and contraction. Failure to
provide this space between the nail head and the panel will cause
the panel to buckle. Do not put a nail into the far right slot until the
overlapping panel is positioned for installation.
Install the next panel by using a dual motion of hooking into the
starter strip and sliding over the previous panel. This will ensure a
proper lap.
Position the overlapping panel so that there is 1/8" to 1/4"
between the panels, depending on the panel temperature at
time of installation. The spacing may appear larger or smaller
than the spaces between the shingles on the panel. This is normal
and necessary in order to allow for expansion and contraction.
Nail in the center of the far left slot of the overlapping panel.
Continue to install the remaining panels of the first course as
described above.
When a window or doorway breaks a course, continue the
application as if the opening were not there.

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.
