What are particles of wood bonded together with waterproof glue called?

The term for particles of wood bonded together with waterproof glue is best described as composition board. This type of wood product is made from various wood fibers or particles that are adhered together, often utilizing adhesives that provide water resistance. This makes it suitable for environments where moisture may be a concern, ensuring durability and longevity in construction or furniture applications.

Composition board is designed to combine the benefits of wood materials while offering enhanced properties due to its manufacturing process, including better use of raw materials and reduced waste. Unlike plywood, which is made from thin layers of wood veneer stacked in alternating directions, composition board is typically created from recycled wood products or wood chips, making it a more versatile choice for many applications.

While composite wood and fiber board can also be related to engineered wood products, the specific characteristic of being waterproofed aligns more closely with the definition of composition board. Plywood does have its own specific properties that differ from those of composition boards, particularly in terms of layering and structural integrity.
