Plywood, masonite, and PINE are all paneling materials commonly used in construction. Plywood is a sheet material made from thin layers of wood veneer glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. Masonite is a type of hardboard made from steam-cooked and pressure-molded wood fibers. PINE is a softwood that is often used for paneling due to its light weight and affordability.
