NAILING PROCEDURES
• DO NOT NAIL TIGHT
• First, nail through center nail 
hole - not nail slot.
• If using partial panel, find center of 
nail hem and drive nail through center 
of nail hem (not in nail slot).
•  Next, nail every 8˝ through center 
of four nail slots.
• Last, nail through slot in left tab.
NOTE:When nailing through slots, 
always nail center of slot, and DO 
NOT NAIL TIGHT. Panels must be 
able to move to allow for expansion 
and contraction caused by tempera-
ture changes.
FIRST COURSE
NOTE: Panels must be installed form 
right to left.
a. Cut the first Panel at “A” ( See 
Figure 10).
NOTE: To Provide for panel move-
ment, allow ¼˝ gap at all corner 
posts, J-Channels, or other stops.
b. Engage bottom lock firmly into 
starter strip. Nail according to  
“nailing procedures.”
c. Side the next panel into position. 
The top half of the panel, except the 
nail hem, slides under, and the bottom 
half slides over the previous panel. 
(See Figure 11)
NOTE: The amount of panel overlap 
is important and varies depending 
on air temperature. Check and moni-
tor air temperature when staring to 
install the first course on each wall. 
See Chart for amount of overlap. (See 
Figure 12). 
d. Nail according to “Nailing 
Procedures.”
e. Install additional full panels, 
repeating steps B-D
INSTALLATION
Last Panel on Each Course
• Measure the distance from the cor-
rect line on the temperature gauge   
into the corner post, less ¼˝.
• Cut off left end of panel.
• Engage lock into starter strip or 
continuous lock of previous course, 
pull up tight and nail according to 
“NAILING PROCEDURES.” 
Installation Tip: Panels will flex to 
allow installation. To minimize waste, 
cut pieces can be used as starter  
pieces on adjacent wall.
Using Alignment lines
NOTE: Temperature gauge is used 
only for installation of the first course 
on each wall. Do NOT adjust temper-
ature gauge on panels after 1st course 
is complete “except when adjusting 
panels for windows or last panel of 
each course”.
