In warehouses should be created special storage conditions for plywood purchased long before use.

• Plywood sheets must be stored only in a horizontal position, without packaging and ties. In vertical position sheets may bend under their own weight and deform. Such sheets will not return to their initial position.
• Plywood should be laid on a prepared pallet.
• Every 50cm of the stack, transversely to plywood sheets, bars with a width of at least 8 cm are laid to prevent sagging.
• The temperature regime of plywood storage should be within the range from -40 ° to + 50 ° С and the level of humidity should not exceed 80%.
• Do not store plywood in damp conditions or near heating appliances.

Keep in mind that buying material for the distant future is not worth. For example, exterior plywood retains its qualities for 5 years from the date of production, while interior plywood will already begin to lose its properties after 3 years from the date of manufacture.
