Cedar has been a reliable standard for years. Ease of installation, a natural resistance to insects and decay, and affordability are all strengths of cedar. Western Red Cedar is the most desirable species and is available in many sizes and grades.

Redwood has become less common but, is still available for prices slightly higher than cedar.
