Installation Instructions

CertainTeed Vinyl Siding Installation Guide

You will need J-channel, starter strip, coil stock and siding. When
choosing a siding panel, remember that wider panels install more
quickly than narrow panels. In addition, panels with decorative
profiles—for example, dutchlap—are impractical for sunburst
applications. For best appearance and easiest installation, choose
from single exposure or larger face double exposure panels.
In addition to standard installation tools, you’ll need a nail hole
punch and a pop rivet gun.
The following instructions assume an installation at a gable end.
Refer to the illustrations for each step.
Plumb J-channels back-to-back in the center of the gable.
Cut the nail hem and lock off a siding panel. Put the pieces aside;
you’ll need them for the final step.
Measure the distance between the J-channel and the rake.
Subtract an allowance for expansion. Cut the panel to this length
(“proper length” in illustration). Trim the panel at the rake end to
match the rake angle.
Cut the panel to the correct taper (third cut). This is a critical
step, because the “flaring” of each panel allows you to create the
sunburst’s arch. To create the taper on a single exposure panel,
start at the channel end of the panel. Mark a point 1-1/2" above
the bottom butt. Then, on the opposite end, mark a point where
the upper edge of the panel meets the rake. (If using double
exposure panels, the mark goes under the center butt. On double
exposure panels, the upper exposure is removed completely.)
Now scribe a line between both points and cut with a utility
knife or snips.
Pop-rivet the nail hem and lock to the trimmed panel. Using the
factory nail hem as a guide, punch slots in the panel. Position the
panel and nail it.
