Shutter Installation
The ideal application (a) has a joint between the two shutters 
where the shutters are secured to the home. In this way, the 
siding panel is not “hard nailed” between the two shutters and 
the siding is allowed free movement.
When there is no joint between the shutters and when the shutters  
are secured to the home (b), the shutters’ fasteners do not 
allow the siding panel to move. The siding panel then fails 
to perform because it cannot expand or contract with the 
temperature changes.
To prevent this, enlarge the holes in the siding for securing 
the shutter—the hole should be 1/4" larger than the shank 
of the fastener. 
If possible, stagger the screws securing the shutter so that they 
do not line up on the same panel. It is also a good idea to apply 
caulk around the screws.
NOTE: See page 76 for fitting siding into narrow openings.
