I did not know you actually were a manufacturer. It does not make sense to join NOFMA if your operation is of that size. There are quite a few manufacturers that do not belong that produce very fine materials and there are also some NOFMA members who materials are questionable. Unfortunately, membership does not guarantee quality. But perhaps consider membership in the NWFA. It may help get you more business.
UPDATE: OK, well, NOFMA's definition of "plank" has changed regarding UNFINISHED flooring. On page #6 of the NOFMA "Installing Hardwood Flooring" Manual (
http://www.nofma.org/Portals/0/Publicat ... Floors.pdf ), they have the nailing schedule. They say strip is 3/4" x 1&1/2", 2&1/4" and 3&1/4". Plank sizes start at 4". However, if you read most information on factory
PREFINISHED flooring, many manufacturers of 3&1/4" widths will call that size "planks". Examples:
http://www.hardwoodinstaller.com/hardwo ... -plank.htm
http://www.hardwoodinstaller.com/hardwo ... -plank.htm
http://www.hardwoodinstaller.com/hardwo ... o-tuff.htm
http://www.hardwoodinstaller.com/hardwo ... -plank.htm
So, it's sorta confusing. As far as UNFINISHED flooring is concerned, plank sizes start at 4", according to NOFMA. However, in factory prefinished flooring, plank sizes start at 3".
