How does the thermal conductivity of cedar compare to metal in outdoor sculptures?

When selecting materials for outdoor sculptures, thermal conductivity is a critical factor influencing durability and performance. Cedar, a popular wood choice, has a low thermal conductivity (around 0.12 W/m·K), meaning it absorbs and releases heat slowly. This property helps cedar sculptures withstand temperature fluctuations without warping or cracking. In contrast, metals like copper (400 W/m·K) or aluminum (237 W/m·K) conduct heat rapidly, making them prone to expansion and contraction in extreme weather. While metal sculptures may feel hotter to the touch under sunlight, cedar remains cooler and more stable. However, metals often provide superior longevity and structural strength. Ultimately, the choice depends on aesthetic preferences, climate conditions, and maintenance considerations. Cedar offers natural warmth and insulation, while metals excel in sleek, modern designs with higher heat tolerance.
