Plywood is manufactured from thin veneers of wood peeled from a log. These
veneers are glued together under high pressure and heat with different glues
being used for different end uses. The veneers are usually laid at right angle
to each other to increase the stability of the board material. Some plywood
has specifc outer veneers e.g. of a hardwood to give an attractive appearance.
Where the outer veneers are of hardwood and the core veneers of softwood
species, the durability will be based on the softwood species.
