**Moisture Mapping** is a crucial tool in building and construction, particularly in preventing wood damage caused by moisture and mold. Understanding wood moisture content and its impact on mold growth is essential for ensuring the longevity of wooden structures.
### Wood Moisture Content
Wood moisture content refers to the amount of water present in wood fibers. The optimal moisture content for wood varies depending on its intended use. Too much moisture can weaken wood, making it susceptible to rot and decay. On the other hand, too little moisture can lead to cracking and warping.
### At What Moisture Content Does Mold Grow on Wood?
Mold growth occurs when wood moisture content exceeds 20%. At this threshold, mold spores can germinate and establish colonies, causing unsightly discolorations, musty odors, and structural damage. High humidity levels, poor ventilation, and moisture leaks can all contribute to elevated wood moisture content, creating a conducive environment for mold growth.
