Western Alder grows in the Pacific Northwest where it thrives on the abundant moisture and frequent rains of Oregon and Washington. A prolific, fast growing hardwood, alder is manufactured into many interior finish products including molding, millwork, patterns and cabinetry. The natural beauty of alder will add warmth and solid-wood charm to any room in a house. Alder is moderately strong, stable when dried, easy to work with, and versatile in its uses.
Disdero Lumber stocks Appearance Grade Alder, 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.
