Installation & Assembly

Decking Installation Guide / v20191125US 9
When installing boards one full length across the deck, we recommended locking the board in the
middle to allow for even expansion and contraction to take place on both ends as shown in Diagram 5.
When installing two boards across the deck, locking clips are recommended to be used at the butt joints
to ensure proper gapping during expansion and contraction as shown in Diagram 6.
Note: When bu jointing boards, sister joisting must be used so that each individual board is on its
own joist to ensure that the board will not slide off the joist, failure to do so will void the warranty,
as shown in Diagram 6. Also there needs to be a minimum of 13/64 inch between the sister joists
for water to go down between the joists or swelling could occur at the ends.
DIAGRAM 5
Expansion and Contraction
We recommend where there is a length of more than two boards needed to make the deck, a breaker
board should be introduced as shown in Diagram 8.
