Wood degradation

Wood degradation is a complex process influenced by various biological, chemical, and environmental factors. It significantly impacts the durability and longevity of wood products and structures, necessitating effective preservation and protection strategies. It primarily involves fungi, bacteria, and insects. Fungi are the most significant agents, causing decay through the breakdown of wood's structural components, such as cellulose, hemicellulose, and lignin.^[1]^[2]

Prevention

Applying preservatives, such as chromated copper arsenate (CCA) or borates, can protect wood from biological and chemical degradation.^[3]

Coatings, such as paints, varnishes, and water repellents, provide a barrier against moisture and UV radiation. Advanced coatings containing UV stabilizers and biocides offer enhanced protection.^[4]
