Western Red Cedar’s natural durability makes it ideal for siding. It exceeds safety classifications, does not require preservative treatments, and is a sustainable product. #3 Knotty pattern stock and square edge boards provide more options for creating your home’s ideal exterior. 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. Although cedar is a naturally durable species, in exterior applications we recommend a protective coating to extend its service life. Cedar boards can be used to build furniture and cabinets where its rustic beauty can bring a piece of the woods into your home or office. Indoors or out, they are simply the best boards and siding available!
