How long should plywood panels be conditioned to the air temperature of the installation space before use?

Conditioning plywood panels to the air temperature of the installation space is crucial for preventing issues such as warping, swelling, or shrinking once they are installed. When plywood is transported or stored in different climates, it may absorb or release moisture, leading to dimensional changes. Conditioning for a period of 48 hours allows the plywood to acclimatize to the environment, ensuring that it reaches a moisture content that aligns with the ambient conditions.

This time frame is generally recommended as it is sufficient for the panels to adjust adequately, helping to maintain their structural integrity once installed. In environments with more significant temperature or humidity fluctuations, extending this period may benefit the plywood further, but 48 hours typically strikes a good balance for most indoor settings.
