Why might teak be less prone to warping than cedar in fluctuating temperatures?

Teak and cedar are both popular choices for outdoor furniture and construction, but teak often outperforms cedar in resisting warping under temperature changes. The key reason lies in their inherent properties. Teak has a tighter grain structure and higher natural oil content, which enhances its dimensional stability. These oils act as a natural barrier against moisture absorption, reducing the wood's tendency to expand and contract with humidity and temperature shifts.

Cedar, while lightweight and aromatic, has a more open grain and lower density, making it more susceptible to moisture infiltration. When temperatures fluctuate, cedar absorbs and releases moisture faster, leading to uneven swelling and shrinking—resulting in warping over time. Additionally, teak's higher density and silica content contribute to its rigidity, further minimizing deformation.

For long-term durability in variable climates, teak's superior resistance to warping makes it a preferred choice for high-quality outdoor projects. Cedar, though cost-effective, may require more maintenance to combat warping in extreme conditions.
