Hello, thank you for your question. Expansion and contraction is a common trait in both of our Composite and PVC decking products which will expand and contract thermally opposed to expanding and contracting from moisture as wood product do. Our installation guides will explain and show how to work with this material and work with the expansion and contraction.
