Introduction
When left untreated in many outdoor applications, wood becomes subject to degradation by a variety of natural causes. Because most commonly used wood species, such as Southern Pine, ponderosa pine, and Douglas-fir, possess little decay resistance, extra protection is needed when they are exposed to adverse environments. Wood can be protected from the attack of decay fungi, harmful insects, or marine borers by applying chemical preservatives. The degree of protection achieved depends on the preservative used and the proper penetration and retention of the chemicals. Wood preservatives that are applied at recommended retention levels and achieve satisfactory penetration can greatly increase the life of wood structures. Thus, the annual replacement cost of treated wood in service is much less than that of wood without treatment. In considering preservative treatment processes and wood species, the combination must provide the required protection for the conditions of exposure and life of the structure. This two-hour continuing education course for architects, engineers and interior designers discusses these topics in detail.
Learning Objectives
After completing this course you will have a better understanding of wood preservative products, techniques and effectiveness, including:
· The Types of wood preservatives, including oilborne and waterborne products;
· The effectiveness of preservatives;
· The effect of wood species on preservative penetration;
· The preparation of timber for preservative treatment, including peeling, drying, conditioning of green products, incising, cutting and framing;
· The application of preservatives, including pressure processes and non-pressure processes, and the effect on mechanical properties;
· The handling and seasoning of timber after treatment, and;
· Quality assurance issues for treated wood, including treating conditions, specifications and inspection.
