Wood Moisture Content

Wood moisture content (MC) is the amount of water present in wood, expressed as a percentage of the wood’s dry weight. It plays a crucial role in the physical and mechanical properties of wood and can significantly affect its performance and durability.

Why is Moisture in Wood Bad?

Excessive moisture in wood can lead to numerous adverse effects, including:

• Warping and Buckling: Moisture expansion and contraction cause wood to warp or buckle, affecting its structural integrity and aesthetic appeal.
• Rot and Decay: High moisture content provides an ideal environment for wood-destroying fungi and bacteria, leading to rot and decay.
• Insect Infestation: Damp wood attracts insects that feed on it, weakening the wood and potentially causing structural damage.
• Reduced Strength and Stiffness: Moisture softens wood, reducing its strength and stiffness, making it less capable of bearing loads.
• Increased Thermal Conductivity: Wet wood conducts heat more readily, making it less energy-efficient for insulation applications.
• Fungal Growth and Mold: High moisture levels promote mold and fungal growth, which can cause health issues and deteriorate wood over time.
