How much gap should I leave for expansion or contraction when ...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. How much of a gap? That will depend upon air temperature at the time of installation (Read this to learn more). For areas that are subject to significant temperature swings, we recommend installing your deck boards using surface fasteners. First, ensure that ...

Lumberock boards do not need to be gapped side-by-side. The amount of expansion/contraction that occurs will depend on the length and temperature of the board at the time of installation. The most significant changes in the length of the board will occur when you are working in extreme temperatures. High altitudes will also increase these es
