How much gap should I leave for expansion or contraction when
How much gap should I leave for expansion or contraction when installing? As temperatures fluctuate, composite deck boards will naturally experience thermal expansion and contraction. That’s why the board ends should never be installed tight against one another. There should always be a slight gap.
Proper Deck Board Spacing: Last Guide You’ll Ever Need
Spacing with composite deck boards is just as important as it is with conventional wood. Like real wood, composite boards will also expand and contract as the humidity changes. Leave at least a 1/8″ gap between composite boards. Determining the gap with pressure-treated decking can be a bit more complicated.
Deck floor board spacing gaps: Proper gap size to leave
The goal is to have about an 1/8-inch gap (the diameter of an 8d nail) between boards after the decking has dried to its equilibrium moisture content. If the decking is installed wet, as is often the case for pressure treated material, it is best to install the boards tight, letting gaps form as the wood dries.

Spacing on a deck refers to the small edge-to-edge gap between decking boards, not the ends of the boards. While this gap is fairly small, it is still a crucial component to any good deck. Without the right deck spacing, the boards may expand, cup, and buckle out of place.
