Characteristics of cedar wood

Sterling Fence Inc has Cedar wood which has these properties:

One of the lightest commercial softwoods, the density of Western Red Cedar at oven-dry conditions is approximately 22 pounds per cubic foot with a relative density (specific gravity) of 0.35. Comparative oven-dry densities of cedar and some other softwood species are given in the table below. Cedar's low density enhances its insulation value and makes it an easy wood to transport and handle.

Dimensional Stability
Like all woods, Western Red Cedar is hygroscopic and will absorb or discharge moisture to attain equilibrium with the surrounding atmosphere. However, it has a very low shrinkage factor and is superior to all other coniferous woods in its resistance to warping, twisting and checking. The size differential between dry and unseasoned Western Red Cedar is given in the table below. Shrinkage in both the radial and tangential directions is given in the table below.
