Moisture Mapping Unveiling the Hidden Secrets of Wood Moisture Content

Wood Moisture Content

Wood is a porous material that can absorb and release moisture from its surroundings. The moisture content of wood is defined as the ratio of the weight of water it contains to the weight of the oven-dry wood. Moisture content is typically expressed as a percentage. Wood with a moisture content below 15% is considered dry, while wood with a moisture content above 30% is considered wet.

Why is Moisture in Wood Bad?

Excessive moisture in wood can have several detrimental effects:

  • Shrinkage and Warping: As wood dries, it shrinks. If the drying process is uneven, this can cause the wood to warp or twist.
  • Fungal Decay: Moisture-rich environments promote the growth of fungi, which can cause wood decay and structural damage.
  • Insect Infestations: Certain insects, such as termites and carpenter ants, are attracted to moist wood and can cause significant damage.
  • Reduced Strength: Wet wood is weaker than dry wood and is more susceptible to damage from loads and impacts.
  • Increased Thermal Conductivity: Wet wood conducts heat more readily than dry wood, making it less effective as an insulator.
