Hardwood Flooring Grades
For more than 100 years, NOFMA certification has provided a mark of distinction for wood flooring. NWFA’s NOFMA certification provides an assurance that wood flooring meets or exceeds industry standards for grade, configuration, moisture content, and average board length. Certified mills are inspected a minimum of twice per year to ensure grading standards are consistently met.
These sample photos provide a good representation of the “look” you can expect from each hardwood flooring grade.
