RH is the Esoteric Measure of Moisture

What is the Best Measure of Moisture?

Relative humidity (RH) is a measure of the amount of water vapor in the air compared to the maximum amount of water vapor the air can hold at a given temperature. It is expressed as a percentage, and the higher the RH, the more water vapor is in the air.

Significance of RH in Water Damage

RH plays a crucial role in assessing and preventing water damage:

• Water Vapor Absorption: High RH increases the air's capacity to hold water vapor. Excess water vapor can condense on surfaces, leading to mold growth and structural damage.
• Drying Process: During water damage restoration, low RH promotes evaporation and drying by extracting moisture from wet materials.

Advantages of Using RH as a Moisture Metric

• Non-Invasive: RH can be measured using sensors without damaging the structure.
• Continuous Monitoring: RH can be monitored over time to track changes in moisture levels.
• Comparative Basis: RH provides a standardized measure of moisture, allowing comparisons between different environments and materials.

Conclusion

RH serves as a valuable metric for understanding moisture levels and their impact on buildings and materials. By monitoring RH, it is possible to identify and mitigate potential water damage risks, ensuring structural integrity and occupant health.
