Thermal Properties - Performance Panels

The average coefficient of linear thermal expansion is about 3.4 x 10-6 inch/inch per degree F for a plywood panel with 60 percent of the plies or less running perpendicular to the face. The coefficient of thermal expansion for panel thickness is approximately 16 x 10 -6 inch/inch per degree F.

Thermal Properties of Plywood | eHow

Thermal expansion doesn't have much of an effect on plywood; it expands minimally per inch of the panel's length for every one degree Fahrenheit of temperature increase, and that's only when the majority of the panel's plies have grain that's perpendicular to the panel surface.
