Western Red Cedar
is one of North America’s great renewable resources. Slow growing and naturally durable, Western Red Cedar has one of the longest life spans of any North American softwood. It produces long lengths of timber with true, straight grain. It is free from pitch and its heartwood has natural decay resistance. Its low density gives it an insulation value superior to most other species. Lightweight, easy to work, easy to finish, possessing excellent dimensional stability, Western Red Cedar is a preferred wood for nearly all purposes where attractive appearance or resistance to weather is important.
One of Western Red Cedar’s most valuable characteristics is its well-known high resistance to decay. It is one of the most durable coniferous species and can be counted on to give long and reliable service under most conditions.
Cedar’s decay resistance comes from the presence of naturally occurring fungicidal compounds in the wood called thujaplicins. Another extractive present in the wood, thujic acid, helps make the wood resistant to insect attack.
Properly finished and maintained, cedar will deliver years of reliable service. If exposed for prolonged periods to conditions where decay could be a factor, such as where the wood is in contact with the ground, cedar should be treated with suitable wood preservatives.
