What are the expansion/contraction rates of WPC in humid climates?
Wood-Plastic Composite (WPC) is a popular material for outdoor applications due to its durability and low maintenance. However, in humid climates, WPC can experience expansion and contraction due to moisture absorption. The expansion rate of WPC typically ranges between 0.1% to 0.3%, while the contraction rate is slightly lower. These changes are influenced by temperature fluctuations and humidity levels. Proper installation with adequate spacing can mitigate potential issues like warping or buckling. Understanding these rates helps in selecting the right WPC products for humid environments, ensuring long-term performance and aesthetic appeal.
