Disdero Lumber stocks two grades of kiln-dried alder.
Superior Grade Alder will yield a high percentage of clear cuttings though some ripping and trimming will be required. Occasional small pin-knots and other natural defects that do not detract appreciable from the general appearance will remain. Finish of this grade is recommended when a mostly clear product is desired.
Appearance Grade Alder is a knotty product containing tight knots and other natural characteristics. Knot size and knot quality are limited depending on the width of the board. Occasional trimming of an undesirable characteristic may be required. Alder of this grade is recommended when a rustic, knotty appearance is desired.
