Oak is generally more expensive than teak. This is due to several factors, including the rarity of certain oak species, the demand for oak in high-end furniture and flooring, and the cost of processing and transportation. According to the American Hardwood Export Council, the average price per board foot of oak can range from $3 to $8, depending on the species and quality. In contrast, teak, which is more commonly used in outdoor furniture and decking, typically costs between $2.50 and $5 per board foot. The higher price of oak is also influenced by the fact that it is often used in high-end applications where aesthetics and durability are paramount.
