Heartwood is reddish to pinkish brown, often with random streaks and bands of darker red/brown areas. Narrow sapwood is pale yellowish white and isn’t always sharply demarcated from the heartwood.
Easy to work with both hand or machine tools, though it dents and scratches very easily due to its softness, and can sand unevenly due to the difference in density between the earlywood and latewood zones. Glues and finishes well. Iron-based fasteners can stain and discolor the wood, especially in the presence of moisture.
Should be moderately inexpensive for construction-grade lumber, though higher grades of clear, straight-grained, quartersawn lumber can be more expensive.
Western Red Cedar is a commercially important lumber, used in a number of applications ranging from rough-sawn lumber for use in home construction to clear quartersawn material for classical guitar soundboards.
