How does teak compare to cedar in terms of resistance to decay?

When comparing teak and cedar in terms of resistance to decay, both woods are highly regarded for their natural durability, but they differ in key aspects. Teak is often considered the gold standard for decay resistance due to its high natural oil content and tight grain structure, which make it highly resistant to moisture, insects, and fungal decay. This makes teak an excellent choice for outdoor furniture, boat decks, and other applications exposed to harsh weather conditions.

Cedar, on the other hand, is also naturally resistant to decay, thanks to its aromatic oils that repel insects and inhibit fungal growth. While cedar is durable, it generally does not match the longevity of teak in extreme outdoor environments. Cedar is commonly used for outdoor structures like fences, decks, and siding, where its lighter weight and affordability are advantageous.

In summary, teak outperforms cedar in terms of decay resistance, especially in demanding outdoor settings. However, cedar remains a cost-effective and durable option for less extreme conditions. The choice between the two ultimately depends on the specific application and budget.
