However, it has a very low shrinkage factor and is superior to all other coniferous woods in its resistance to warping, twisting and checking. 2. Review specification options of Western Red Cedar, including lumber and appearance grades, as well as compatible fastener selection. The simple cell structure of softwoods’ long, uniformly packed fibers gives them a high strength-to-weight ratio, making them flexible and capable of bearing heavy loads. What Western Red Cedar lacks in strength, it makes up for in appearance. Only a couple of species of Cedrus exist in the world, but they exhibit certain traits that make them very popular.

Softwoods have been exported from the United States for over 400 years. It is non-resinous and has a strong spicy scent. They are used in conjunction with flame spread ratings to regulate the use of interior finish materials where the potential to generate smoke or control smoke movement is of major fire safety importance. produces cedar of Lebanon, a native of the Middle East. 0000004585 00000 n Our BCA consultant requires confirmation that the western red cedar is a … SP-37R) Co-published by Western Red Cedar Lumber Association and Western Red Cedar Export Association. rȋ8��/�Jy In this article, I describe forty facts about the plant and the importance of the “tree of life” in the local culture.

Fasteners should be corrosion resistant such as aluminum, hot-dipped galvanized or stainless steel. 1. Western Red Cedar especially is superior to steel, concrete, and brick in this respect. Wood is an excellent thermal insulator. British grown western red cedar generally has similar properties to material imported from North America. Western Red Cedar’s thermal properties include: A … Western Red Cedar Beams Full dimension beams. These superior ratings allow for cedar to be used in the interior of a structure without the need for treatment. Western Red Cedar is used to manufacture a range of specialty products such as siding, paneling, structural decking and outdoor decking. One of the lightest commercial softwoods, the density of Western Red Cedar at oven-dry conditions is approximately 21 pounds per cubic foot with a relative density (specific gravity) of 0.32. Design values provided for Western softwood species manufactured and shipped by mills in the 12 contiguous Western states and Alaska. Forest Products Laboratory, Forest Service … Western Red Cedar is used to manufacture a range of specialty products such as siding, paneling, structural decking and outdoor decking. So we can't just say that western red cedar is a Group 3 material in all cases. With its low density and high proportion of air spaces, Western Red Cedar is the best thermal insulator among the commonly available softwood species and is far superior to brick, concrete and steel.
