Installation Guide

Expansion and Contraction Values Continued
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 7.

Expansion and Contraction Values Continued
When installing boards two boards are installed 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 8.
Note: When butt 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 8.

Locking Clips
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 9.
