Moisture Mapping Understanding Wood Moisture Content and Mold Growth

Wood Moisture Content

Wood moisture content refers to the amount of water present in a piece of wood, expressed as a percentage of its dry weight or oven-dry weight. Measuring wood moisture content is essential for determining its stability, durability, and susceptibility to decay and fungal growth.

At What Moisture Content Does Mold Grow on Wood?

Mold commonly requires a wood moisture content of 20% or higher to thrive and reproduce. Once mold establishes on wood, it can cause discoloration, damage the wood structure, and pose health risks. Therefore, maintaining wood moisture content below 20% is crucial for preventing mold growth.

Moisture Mapping

Moisture mapping is a non-destructive technique used to measure and visualize the distribution of moisture in building materials, including wood. Using specialized equipment, moisture mappings help identify areas with high moisture levels that could support mold growth. This information guides targeted interventions to address moisture issues and prevent potential damage.
