This CP describes sawn lumber intended for light structural framing (wall framing, sill plates, etc.), also known as “dimensional lumber” in the industry. Boards are cut in standard dimensions: 2x4 or 4x4 inches by 10 feet, are commonly used in framing, for example. Because the lumber is intended for interior applications, it is not typically pressure treated. Instead, the lumber is sawn from logs to the appropriate dimensions and air or kiln dried to 19% humidity. To prevent discoloration, known as sapstain, from forming, dimensional lumber is routinely dipped in a bath, or sprayed with a fungicidal treatment that inhibits the growth of microbes naturally found in freshly cut timber.
