### Wood Moisture Content
Moisture content (MC) in wood describes the amount of water present within its structure relative to its dry weight. Wood MC directly affects its physical properties, such as dimensional stability, strength, and susceptibility to decay.
### At What Moisture Content Does Mold Grow on Wood?
Mold requires a certain level of MC to thrive. Typically, wood with an MC of **20% or higher** provides a conducive environment for mold growth. At this MC, mold spores can germinate and colonize the wood fibers, leading to discoloration, decay, and potential health hazards.
### Role of Moisture Mapping
Moisture mapping is a technique used to identify areas of high MC in wood structures. This information can be used to:
– Prevent mold growth by implementing targeted drying measures
– Assess the extent of moisture damage
– Determine the optimal conditions for wood treatment and restoration
– Monitor the effectiveness of moisture control strategies
### Benefits of Moisture Mapping
– Accurate assessment of moisture levels
– Early detection of potential moisture problems
– Targeted moisture mitigation
– Improved building performance and occupant health
