Does Baleboard® shrink or expand with temperature changes?
Yes, all plastic lumber products exhibit some degree of expansion and contraction due to temperature extremes. Our lab test results show that with Baleboard®, there is greater shrinkage in cold temperatures, than expansion in heat. Shrinkage and expansion occurs lengthwise, and Baleboard® does resume its original size with the original temperature. Shrinkage can be reduced by using more fasteners throughout the length of the board.
