CertainTeed Vinyl Siding Installation Guide

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.
T5" Straight Edge Perfection Shingles
Panel Spacing at Different Temperatures
See pages 94 to 95.
NOTE: Do not drive center-pin nails tight. Leave 1/8"–1/16"
between the nail head and the panel to allow the panel to
move freely during normal expansion and contraction.
First course
Strike a level line around the house and install Cedar Impressions
Metal Starter Strip. If you plan to use Cedar Impressions Mitered
Cornerposts, make sure the starter strip is installed to the edge of
the corner. An alternative method of starting Cedar Impressions
is to use J-channel in place of starter strip to receive the bottom
edge of the panel.
Create a straight edge on the right side of the panel by cutting
the top two shingles so they are flush with the bottom shingle.
Cut the end of the top course of the panel at indicator “A,”
which is located above the nail slots.
