How does the thermal expansion of WPC compare to solid wood in outdoor bench applications?

When selecting materials for outdoor benches, understanding thermal expansion is crucial for long-term durability. Wood-Plastic Composite (WPC) and solid wood are popular choices, but they behave differently under temperature changes. WPC, a blend of wood fibers and plastic, exhibits lower thermal expansion compared to solid wood. This means WPC benches are less likely to warp, crack, or swell when exposed to fluctuating outdoor temperatures. Solid wood, while aesthetically pleasing, is more susceptible to expansion and contraction due to its natural composition. In outdoor applications, WPC's stability makes it a reliable option for maintaining structural integrity over time, even in extreme weather conditions. Choosing WPC over solid wood can reduce maintenance needs and extend the lifespan of outdoor benches.
