### Understanding Wood Moisture Content
Wood moisture content (MC) refers to the amount of water present in the cellular structure of wood and is expressed as a percentage of its dry weight. Ideally, wood should be dried to an optimal moisture level to enhance its durability, performance, and resistance to damage.
### Why is Moisture in Wood Bad?
Excessive moisture in wood can lead to a range of undesirable consequences:
– **Warping and Buckling:** Moisture causes wood to expand or contract, leading to distortions such as warping and buckling.
– **Decay and Rot:** High moisture levels create a conducive environment for fungi and bacteria that cause decay and rot.
– **Expansion and Contraction:** Fluctuations in moisture content cause wood to expand and contract, potentially damaging structures and finishes.
– **Reduced Strength and Stability:** Excess moisture weakens wood fibers, affecting their structural integrity and stability.
– **Increased Conductivity:** Moist wood conducts electricity, raising the risk of electrical hazards.
– **Corrosion and Metal Damage:** Moisture can cause corrosion in metal components, such as nails and fasteners, compromising their effectiveness and posing a safety hazard.
