Securing Panels Around 
Windows
• Measure and cut panels around 
windows, allowing ¼˝ into all win-
dow channels for movement. (see 
Figure 16).
• Make sure to install water diverters 
at the bottom corners of the   
window (refer to Basic Accessory 
Installation Section “Installing   
J-Channel, Flex-J and Flashing”).
• Use a nail slot punch to create nail 
slots every 8˝ on the cut edge of the 
panel.
• Furr as needed.
• Slide panel into window channel.
• Pull up tight and nail according  
to “NAILING PROCEDURES”   
(window channel must conceal  
nail-heads).
Installation Tip: A nail set can be 
used to ease installation.
Installing Final Course
NOTE: A crown molding, J-channel 
or wide window casing can be used in 
eaves and gables to receive the final 
course (see Figure 17).
• Measure the required width for 
last course less ¼˝ to allow for panel 
movement.
• Cut panel height as required.
•  Punch nail slots every 8˝.
• Nail through center of slots.
NOTE: Furring may also be required.
