Wood panel products are essential materials used in construction for applications such as flooring, siding, and roofing, typically available in standard dimensions of 4 feet by 8 feet, with thicknesses varying from one-quarter of an inch to one and one-eighth inches. Among the most common types of wood panels is plywood, which is produced by gluing multiple layers of thin wood veneers under pressure. The grain of the outer veneers runs lengthwise, while the grains of the interior layers run widthwise, providing stability and strength. Plywood is characterized by having an odd number of layers to maintain structural balance.

Composite panels consist of two parallel surface veneers bonded to a core made from densely packed, reprocessed wood fibers, ensuring a strong and uniform structure. Alternatively, oriented strand boards are made from elongated wood shreds that are compressed and bonded into three to five layers, with the strand arrangement in each layer designed to mimic the grain alignment in plywood.

Particleboard is another type of panel made by compressing and gluing smaller wood particles together, often used in furniture manufacturing due to its smooth finish and consistency. Fiberboard, similar in construction to particleboard, uses compressed wood fibers mixed with synthetic resins to create a finely textured and highly durable board. These diverse wood panel products offer various solutions for construction and manufacturing, each tailored to meet specific structural and aesthetic requirements.
