Blockboard is a type of engineered wood product commonly used in woodworking and furniture construction. It is composed of a core made from solid wood blocks or strips that are sandwiched between two layers of veneer or plywood. The core blocks are typically arranged with their wood grain running parallel to each other, and they are glued together to form a solid and stable core structure. The outer veneer layers provide a smooth and attractive surface finish.

Blockboard is known for its strength, stability, and resistance to warping. It is often used in applications where a sturdy and flat surface is required, such as in furniture panels, doors, tabletops, and cabinetry. The combination of solid wood blocks in the core and the outer veneer layers gives blockboard the advantages of both solid wood and plywood, making it a versatile choice for various woodworking projects.
