Moisture Mapping Understanding Wood Moisture Content and Its Harmful Effects

Wood Moisture Content

Wood is a hygroscopic material, which means it can absorb and release moisture from the surrounding environment. The moisture content of wood is expressed as a percentage of the weight of the oven-dry wood. The moisture content of wood can vary significantly, depending on the species of wood, the environmental conditions, and the age of the wood.

Why is Moisture in Wood Bad?

Excessive moisture in wood can have several detrimental effects, including:

  • Warping and shrinking: Moisture can cause wood to warp or shrink, which can lead to structural problems and unsightly appearance.
  • Fungal growth: Moisture provides the ideal conditions for fungal growth, which can damage or destroy wood.
  • Insect infestation: Insects are attracted to moisture, and they can bore through wood, causing significant damage.
  • Loss of strength: Moisture can weaken the strength of wood, making it more susceptible to damage.
  • Fire hazard: Dry wood is more flammable than wet wood, and excessive moisture can increase the risk of fire.

Moisture Mapping

Moisture mapping is a technique used to measure the moisture content of wood. This can be done using a variety of methods, including moisture meters, infrared cameras, and electrical resistance probes. Moisture mapping is an important tool for assessing the condition of wood and for identifying areas of high moisture content that may need to be addressed.
