basic installation
horizontal siding installation
Step 1
The first panel (or course) should
be placed in the starter strip and
securely locked along the entire
length of the siding panel.
NOTE: Always overlap joints away
from entrances and away from the
point of
greatest traffic. This will improve the
overall appearance of the
installation.
Step 2
Be sure to fasten the panels
according to the instructions on
page 14. Allowance should be made
for expansion and contraction by
leaving a 1/4˝ gap between the siding
and all corner posts and channels
(increase to 3/8˝ when installing in
temperatures below 40ºF).
Step 3
Do not drive the head of the fastener
tightly against the nail slot. Leave
1/32˝ between the fastener head and
the panel nailing strip.
Step 4
Do not stretch the panels up when
fastening. Panel locks should be
fully engaged; however, the panels
should not be under vertical tension
or compression when they are
fastened.
Step 5
Since vinyl siding moves as the
temperature changes, make certain
that the vinyl panels can move freely
in a side-to-side direction once
fastened.
Step 6
Check every fifth or sixth course
for horizontal alignment (Fig. 1).
[Check siding alignment with
adjoining walls]
Step 7
When panels overlap, make sure they
overlap approximately 1˝ (Fig. 2).
NOTE: Overlap with factory ends
whenever possible. If you must
use cut ends, duplicate the factory
notches before installing. Avoid stair-
step lapping.
Step 8
Stagger the siding end laps so that
no two courses are aligned vertically,
unless separated by three courses.
