Moisture Mapping Understanding Wood Moisture Content

Wood Moisture Content

Moisture content in wood refers to the amount of moisture present in the wood, typically expressed as a percentage of the oven-dry weight of the wood. Wood moisture content significantly influences the wood's physical and mechanical properties, including its strength, durability, and susceptibility to damage.

What is the Moisture Content in Wood?

Wood moisture content varies depending on several factors, including:
  • Tree species
  • Wood density
  • Drying conditions
  • Environmental conditions (temperature and humidity)
Generally, freshly cut wood contains high moisture content, exceeding 30%. Through natural drying or kiln drying, the moisture content is reduced to an equilibrium moisture content that balances with the surrounding environment. The moisture content of wood is crucial for its performance in various applications. For example, excessively high moisture content can lead to wood decay, while excessively low moisture content can cause wood to become brittle and susceptible to cracking. Therefore, it is essential to monitor and control wood moisture content to ensure optimal performance and longevity.
