Western Red Cedar
Thuja plicata • Softwood
Grain Pattern
Straight grain with a medium to coarse texture; this sample shows a rough-sawn/fuzzy surface and contains a tight, round knot with a minor drying check.
Color Description
Heartwood ranges from reddish to pinkish brown, often with random streaks of darker brown. The sapwood is a pale yellowish white. It tends to weather to a silver-grey if left outdoors and untreated.
Hardness Rating
350 lbf (Very Soft)
Durability Rating
Durable to Very Durable regarding decay resistance, though less resistant to insect attack; high tannin content provides natural protection against rot.
Common Uses
Outdoor siding, decking, shingles, fence posts, greenhouse construction, boat building, and closet liners.
Geographic Origin
Pacific Northwest of North America (British Columbia to Northern California).
Market Value & Sustainability
Estimated Market Value
Approximately $4.00 - $8.00 per board foot depending on grade (Clear vs. Common) and regional availability.
Wood Age Estimate
Relatively recent/contemporary production; the light color and lack of deep silvering or heavy patina suggest the lumber is between 1-5 years old and has been stored indoors or in a dry environment.
Sustainability Status
Least Concern (IUCN); widely available with FSC certification; highly sustainable due to abundant growth and responsible harvesting in North America.
Workability
Easy to work with hand and machine tools, though very soft and prone to denting and scratching; glues and finishes well; can be prone to splintering due to its brittle nature.
Notable Features
Distinctive aromatic 'cedar' scent; very lightweight; high resistance to moisture and thermal expansion; contains tannins that can react with iron fasteners to cause black staining.
Finish Recommendations
Penetrating oils or transparent stains are best to preserve the natural color; if used outdoors, UV-inhibiting finishes are required to prevent graying.
Identification Confidence
High; the reddish-tan hue, prominent latewood lines, presence of a typical softwood knot, and the characteristic 'fuzzy' rough-sawn texture are diagnostic for Thuja plicata.
