Abstract
This chapter deals with wood degradation and protection of wood-based materials. Wood degradation can be classified as damage caused by biotic and abiotic agents. Non-living or abiotic agents include weathering, mechanical wear, chemicals, and heat. Biotic agents include bacteria, fungi, insects, marine borers, and woodpeckers. The chapter reveals that wood can be protected against biological degradation by limiting one or more of the four basic factors required for growth-that is, oxygen, temperature, moisture, and food source. Non-durable woods can be supplementally protected with chemicals. This method is known as "wood preservation." Wood treatment can be divided into short-term protection lasting less than six months and longer-term protection that may need to last 50 or 100 years. The amount of chemical and the depth to which it must be applied to be effective differ substantially from that needed to protect wood exposed in soil in a tropical environment for many years. The chapter describes various treatment methods, such as brushing, dipping or soaking, two-stage dip diffusion, and thermal treatment.
