Made from compressed layers of wood chips and adhesives. This manufacturing process is called cross-graining and it reduces shrinkage and expansion while improving panel strength consistency. Composite plywood differs from the standard panels because it comes with a core of particleboard or solid timber covered with a wood veneer. The making of the composite uses the fibers, glue, and heat to create a tight bonding board. When used for roofing, plywood panels are covered and protected by a variety of building materials that keep the elements at bay, including roof felt, underlayment, flashing and shingles. Made from compressed wood fibers and adhesives, sometimes using a mold. Although specialty plywood can have any number of plies above three, most plywood is categorized as 3-ply, 5-ply or multi-ply.
