Moisture Mapping Guide Wood Moisture Content and Mold Growth

Moisture Mapping is a crucial process for ensuring the optimal performance and longevity of wood structures. Understanding the relationship between wood moisture content and mold growth is essential for effective moisture management.

Wood Moisture Content

Wood moisture content refers to the amount of water present within the wood fibers. It is typically expressed as a percentage of the wood's dry weight. The moisture content of wood can fluctuate due to environmental factors such as temperature, humidity, and rainfall.

At What Moisture Content Does Mold Grow on Wood?

  • Mold growth on wood is influenced by several factors, including moisture content.
  • Mold can begin to grow on wood when the moisture content exceeds 20%.
  • At 28%, mold growth becomes more prevalent and can cause significant damage to the wood.
  • Excessive moisture can also lead to other problems such as wood rot and decay.
