Eco-board is generally more expensive than oak. This is due to several factors, including the production process, availability, and quality. Eco-board, also known as engineered wood, is made from recycled wood fibers and other materials, which can be more expensive to produce than solid oak. Additionally, oak is a widely available and popular wood species, which can drive down its price. According to the American Hardwood Export Council, the average price per board foot of oak in 2021 was $4.50, while eco-board prices can vary widely but are often higher, with some grades exceeding $6 per board foot.
