Why Cedar? I get asked this question all the time!
Why Real Cedar Has Been America's Outdoor Choice For Centuries
Cedar's durability is legendary. Its natural resistance to moisture decay and insect damage makes Western Red Cedar the ideal choice for structures that are exposed to sun, rain, heat, and cold all year round.
Western Red Cedar is the stability leader. It has long straight grains that resist twisting, warping, cupping, setting, and shrinking. This has been why Western Red Cedar has long been the the choice outdoor wood for custom home builders.
Lets not forget that cedar is a renewable resource. Western Red Cedar is harvested from sustainable forest management. Cedar Substitutes such as plastic, concrete, vinyl... which are material extracted from the earth - once removed they can never be replaced. Once theses cedar substitutes complete their useful life, they end up in a land fill site. Cedar is 100% biodegradable, not to mention the energy that went into producing the plastic substitutes. Cedar is 100% natural beauty produced by the sun and earth in harmony.
Here is some more information I think you will find interesting. It is taken from the Western Red Cedar Lumber Association http://www.cedar-outdoor.org/
The conduction of heat in wood is directly related to its density. Woods with low density have the highest thermal insulating value because such woods contain a high proportion of cell cavities. In dry wood, these cavities are filled with air which is one of the best known thermal insulators.
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. It has a coefficient of thermal conductivity (k value) at 12% mc of 0.74 BTU in. per square ft.h degrees F. The R value (the reciprocal of k) for Western Red Cedar is 1.35" of thickness.
Properly finished and maintained, cedar will deliver decades of trouble-free 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.
Products, Grades and Sizes
Western Red Cedar (Thuja plicata) 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. Light weight, easy to work, easy to finish, possessing outstanding dimensional stability, Western Red Cedar is a preferred wood for nearly all purposes where attractive appearance or resistance to weather is important.Features of Western Red Cedar
