What spacing prevents thermal expansion gaps in WPC?
When installing Wood Plastic Composite (WPC) decking, proper spacing is crucial to prevent thermal expansion gaps. WPC materials expand and contract with temperature changes, and without adequate spacing, gaps can form, leading to structural issues. To avoid this, maintain a spacing of 1/8 to 1/4 inch between boards during installation. This allows the material to expand without causing warping or buckling. Additionally, ensure proper ventilation beneath the deck to minimize moisture-related expansion. Following these guidelines ensures a durable and long-lasting WPC deck.
