The National Wood Flooring Association has released a new international standard for factory finished solid wood flooring. The new standards, which were finalized in March, provide detailed configuration guidelines and machining tolerances for manufacturing solid factory finished wood flooring.

The guidelines provide specific criteria for width, match position, tongue thickness, groove width, end match, thickness, over and underwood, bevels, moisture content, grading, gloss level, finish adhesion, board length, color match, square footage, crooks, finish warranties, packaging, and board identification.

These standards were developed through the collaboration of numerous NWFA member companies, many of whom are competitors in the industry, in an effort to provide universally recognized guidelines for the benefit of the entire wood flooring industry.

Recently, Herwynen Saw Mill, Ltd. (Superior Flooring) became the first company to become certified under the program. Herwynen is located in Rockwood, Ontario, Canada.
