Exterior plywood is an engineered panel built up of veneer plies.
The thickness and orientation of the plies determine the performance of the panel. The veneer sheets are united under high temperature and pressure with phenol-formaldehyde adhesive, a waterproof adhesive, making the plywood suitable for exposedconditions. This chapter presents a sampling of potentially breakthrough, technological innovation in the panel industry. The examples provided would apply in most cases to a number of the panel sectors but one sector may be a leading candidate. The list is not exhaustive nor does it imply priorities.
