The National Oak Flooring Manufacturers Association (NOFMA) recently adopted new standards to define acceptable configuration and tongue-and-groove fit for solid wood flooring. The standards establish maximum allowable tolerances for overwood, side matching, flooring, width, and end match squareness.

To maintain NOFMA certification, manufacturers must meet the new standards. For more information, visit www.nofma.org or email NOFMA at info@nofma.org.
