the thermal expansion of wood in the direction of the grain is very little. in the radial and tangential directions, temperature movements are much greater. the relationship between the thermal expansion coefficients and moisture contraction coefficients of wood in different directions relative to the grain is in the same class in terms of size.

as temperatures fluctuate, composite deck boards will naturally experience thermal expansion and contraction. thats 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 .
