Wood Moisture Content

Wood moisture content (MC) refers to the amount of water present in wood fibers. It is crucial for ensuring the durability and stability of wood products.

At What Moisture Content Does Mold Grow on Wood?

Mold growth occurs when wood MC exceeds a specific threshold. The optimal MC for mold growth ranges between 20% and 30%. At these moisture levels, mold spores readily germinate, colonize, and spread throughout the wood, leading to the potential for decay and structural damage.

Moisture Mapping

Moisture mapping is a valuable technique for identifying and addressing moisture issues in wood structures. It involves using specialized tools, such as moisture meters, to measure moisture levels at various locations within the wood. This data enables professionals to develop targeted moisture management strategies, such as:

• Identifying and addressing moisture sources (e.g., leaks, condensation)
• Selecting appropriate moisture control measures (e.g., ventilation, dehumidification)
• Monitoring ongoing moisture conditions to ensure the effectiveness of mitigation measures

By controlling moisture levels in wood, we can significantly reduce the risk of mold growth, decay, and other moisture-related damage, extending the lifespan and preserving the integrity of wood structures.
