How does moisture absorption differ between WPC and solid wood?

Moisture absorption is a critical factor when choosing materials for outdoor applications like decking or furniture. WPC (Wood-Plastic Composite) and solid wood differ significantly in how they handle moisture. Solid wood, being a natural material, is highly porous and absorbs moisture easily, leading to swelling, warping, and potential rot over time. In contrast, WPC is engineered to resist moisture absorption due to its plastic component, which creates a barrier against water penetration. This makes WPC more durable and low-maintenance in humid or wet environments. Additionally, WPC's resistance to moisture reduces the risk of mold and mildew growth, making it a preferred choice for outdoor use. Solid wood, while aesthetically pleasing, requires regular sealing and maintenance to protect it from moisture damage. Understanding these differences can help you make an informed decision based on your specific needs and environmental conditions.
