Standard wood panels used for flooring, siding, and roofing have dimensions of 4 feet by 8 feet in width and length, and their thickness can range from one-quarter of an inch to one and one-eighth inches.
Wood panels, such as plywood, are made by gluing multiple thin wood veneers together under pressure.
The veneer grains on the exterior run lengthwise, while interior veneers have grains running widthwise.
Plywood has two exterior layers that sandwich either one or two interior veneer layers.
Composite panels have two parallel surface veneers that securely adhere to a reprocessed, densely packed wood fiber core.
Panels that are not veneered are oriented strand boards produced from elongated wood shreds, which are compressed and bonded into three to five layers.
The strand arrangement in each layer is similar to the grain alignment in plywood's veneer layers.
Particleboard is produced by gluing together smaller wood particles and compressing them to form durable panels.
Fiberboard is a finely textured board made from compressed wood fibers and strong artificial resin binders.
