Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight grain with distinct flat-sawn cathedral patterns showing prominent latewood bands and occasional small knots
Color Description
Heartwood varies from yellowish-tan to reddish-brown; sapwood is narrower and lighter. Darkens to a more pronounced orange or reddish-brown with exposure to UV light.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack.
Common Uses
Construction framing, heavy timbers, flooring, cabinetry, interior trim, and boat building.
Geographic Origin
Western North America, particularly the Pacific Northwest.
Market Value & Sustainability
Estimated Market Value
$3.00 to $7.00 per board foot depending on grade (Vertical Grain commands higher prices).
Wood Age Estimate
The visible oxidation and finish suggest the installation is 10-30 years old, appearing as seasoned interior millwork.
Sustainability Status
Not CITES listed; classified as Least Concern by IUCN. Widely available with FSC certification from managed forests.
Workability
Generally easy to work with machines, but can be prone to splintering and tearout. It glues and finishes well, though it can exhibit uneven staining without a sealer.
Notable Features
Distinctive resinous scent when cut; known for its excellent strength-to-weight ratio among softwoods.
Finish Recommendations
Clear polyurethane or lacquer to preserve the natural look. A pre-stain wood conditioner is recommended if using dark stains to prevent blotchiness.
Identification Confidence
High; the combination of prominent reddish latewood growth rings, flat-sawn cathedral shapes, and use in architectural paneling is characteristic of Douglas Fir.
