Typical Mouldng Use
Wood Mouldings


Wood mouldings are available in two grades. "N Grade" is intended for natural or clear finishes and the exposed face must be of one single piece. "P Grade" is intended for opaque paint finishes or overlays and can be finger jointed and or edge glued.

These grades may have a few minor characteristics such as light checks, small pitch pockets, light torn grain, pin-size or small knots, occasional medium stain or a small amount of medium pitch. A serious combination of these is not admissible in any one piece. The number and of characteristics per-mitted varies as the area of the piece increases or diminishes.

N-GRADE (suitable for natural, stain, paint or enamel finish)

On the basis of net 2" face – 12’ long this grade will admit the following characteristics or their equivalent.

  • A small spot of torn grain, one foot of medium pitch, light skip in dressing on back, or

  • One small and one very small pitch pocket, or

  • One short tight season check and a light snipe at one end, or

  • Medium stain in occasional (10%) pieces for one third the area in an otherwise perfect piece

 Characteristics that will not show when piece is laid shall not be given the same consideration as characteristics elsewhere.


P-GRADE (paint or overlay grade)

The same quality as N-Grade except stain is no defect. Glue joints (laminated or finger joints) must be precision machined and assembled with tight joints. Patching, filling or plugging is permitted providing a paintable surface results.



Random lengths shall be 3 to 20 feet in multiples of one foot. Not over 15% of any one item shall be un-der 8 feet. When computing the percentage of shorts in casing and stops, pieces 7' in length will be considered long lengths.

Specified lengths of cut to length window and door trim shall be graded as completely useable.

Finger and/or laminated jointed mouldings may be ordered in specified lengths with not over 15% trimbacks permitted in any one item.



Adhesives used in finger joints or laminations shall meet the dry use adhesive performance requirements of ASTM D-3110-72 (or latest revision) "Standard Specification for Adhesives Used in Non-Structural Glued Lumber Products."

In situations where a Wet-Use adhesive is required, it shall be so specified, acknowledged and in-voiced.



Bundling shall be in accordance with the Standard Western Wood Moulding and Millwork Producers Schedule.



Thickness and width + or - 1/32"



Definitions of characteristics permitted in wood mouldings shall be those of the National Grading Rules for softwood lumber.



In determining compliance with purchase specifications and of effecting settlement of invoices between buyers and sellers, each item of a shipment shall be considered as of the grade invoiced if upon re-inspection 95% thereof or more is found to be of said grade or better.
