Yes. Deckorators decking must be gapped at the ends to allow for expansion and contraction and gapped between boards for water runoff. At the ends of the deck boards, allow a minimum of 1/16" gap for every 20°F of difference between the installation temperature and the hottest temperature expected. Allow a 1/4" gap between the deck boards and between all decking and any permanent structure or post for water runoff. For more information, refer to the installation instructions.
