How should you store lumber in self storage units?

• Lumber stored vertically should be raised off the ground to prevent water damage, and be supported at the top and bottom to prevent bowing.

• Store your lumber in a clean, cool, shaded and dry location. If you're storing wood in an area with high relative humidity—80 percent or more—be sure it's wrapped in material that is impermeable to vapor. This prevents the wood from absorbing significant amounts of moisture from the surrounding air.
