Western Red Cedar
Thuja plicata • Softwood
Grain Pattern
Straight, flat-sawn with prominent cathedral patterns, showing tight growth rings and occasional small knots around branch junctions.
Color Description
Heartwood ranges from reddish-pink to a medium brown; sapwood is yellowish-white. This sample shows a warm, reddish-brown patina from oxidation and light exposure, with a medium natural luster.
Hardness Rating
350 lbf (Very Soft)
Durability Rating
Durable to Very Durable; excellent resistance to rot, decay, and weather-related swelling/shrinking. Moderate resistance to insect attack.
Common Uses
Decking, siding, shingles, outdoor furniture, boat building, fence posts, interior paneling, and sauna construction.
Geographic Origin
Pacific Northwest of North America (British Columbia down to Northern California).
Market Value & Sustainability
Estimated Market Value
$5.00 - $12.00 per board foot depending on grade (clear vs. knotty) and thickness.
Wood Age Estimate
Modern era; likely harvested within the last 10-20 years. The surface shows some oxidation but lacks the deep graying of reclaimed old-growth cedar.
Sustainability Status
Least Concern (IUCN); widespread and sustainably harvested in North America. FSC certified options are commonly available.
Workability
Easy to work with both hand and machine tools, though very prone to bruising and denting due to low density. Sands easily but can clog fine sandpaper. Excellent gluing and finishing properties.
Notable Features
Strong, pleasant, aromatic scent; very lightweight; natural oils provide decay resistance but can cause allergic reactions (respiratory) in some woodworkers; high tannin content can cause dark stains if in contact with iron fasteners.
Finish Recommendations
An oil-based sealer or polyurethane is recommended to preserve color. For outdoor use, a UV-inhibitor is necessary to prevent graying. Clear finishes highlight the natural warmth of the grain.
Identification Confidence
High; the distinctive cathedral grain, warm reddish-brown hue typical of oxidized heartwood, and the spacing of growth rings are classic indicators of Western Red Cedar.
