Installation Instructions

These instructions describe and illustrate the steps
i
nvolved in installing CertainTeed siding and trim. Their
purpose is to provide detailed information and how-to
tips that will simplify the installation process. CertainTeed
shall not accept any liability or responsibility under its
written warranty for failure caused by application that
does not meet our minimum requirements for proper
installation. These requirements are outlined throughout
the
CertainTeed Installation Guide (CTS205). Any
deviations from these requirements should be approved
in writing by CertainTeed Corporation.
NOTE: Vinyl siding must be applied over a rigid
sheathing that provides a smooth, flat surface or an
underlayment (such as wood, wood composition,
rigid foam or fiber sheathing) that is no more than 1"
thick. Vinyl siding cannot be applied directly to studs.
The installation of a Northwoods Shakes or Shingles
panel is unique in that the lap joint is hidden in the ribs
between the shake or shingle patterns. Positioning the
laps in the rib area requires that special installation
procedures be followed to maintain product
performance and aesthetics.
Factory Laps: All lap joints are cut at a predetermined
point on the panel during the manufacturing pr
ocess. All
male laps must be factory cut. Female laps may be cut
using the gap. However, do not cut along the edge of
the gap; leave 3/16" of the gap for the overlap.
Panels must be installed from right to left. The left panel
will overlap the right panel.
Center Pinning
Vinyl siding expands and contracts as the temperature of
the panel changes. T
o maintain the pr
oper rib width at
the lap joint, you will have to limit the movement of the
panels. T
o do this, you must center pin each panel.
Center pinning pr
events the rib width at the lap joint fr
om
becoming too wide or too narrow. Each panel contains a
short vertical slot, which is perpendicular to the nail
slots. This slot marks the center of the panel.
Center pin
each panel regardless of its length.
Installation procedure for fully nailable substrate
Lock the right side panel into place on the starter strip.
Allow room for expansion and contraction in all
accessory pockets:
• 1/4" if the ambient temperature is above 40° F.
• 3/8" if the ambient temperature is below 40° F.
Locate the short, vertical slot on the nail hem and center
pin the panel in this location using one of the following
options:
a. Install a nail on both ends of the same nail slot.
b. Pin the panel by fastening directly through the nail
hem.
c. Drill a 3/16" diameter hole through the nail hem
and substrate, and place a single fastener through
this newly drilled hole.
Install nails in the center of the remaining slots, 16"
apart. Leave adequate r
oom between the fastener
head and the nail flange for expansion and contraction
(approximately 1/16" to 1/8"). Do not hard nail these
fasteners.
Install the next panel to the left of the installed panel.
Lap this panel over the installed panel, positioning the
right edge of the panel to the appropriate temperature
mark, which is located in the factory notch area.
Fasten the panel according to the procedure described
earlier
.
Continue the first course of siding, r
emembering to
center pin
ALL panels.

If the ambient temperature is
less than 45°F,
lap the panel to
the first (30°) mark.
If the ambient
temperature
is between
45°F - 80°F, lap
the panel to the
second (65°) mark.
If the ambient
temperature is
greater than 80°F,
lap the panel to the third (100
°) mark.
