What Should Moisture Readings Be for Internal Walls?
Internal walls, particularly those made of gypsum board or plaster, are susceptible to moisture damage. Determining the appropriate moisture levels is crucial to prevent structural issues or health hazards.
Moisture Content Guidelines
- Ideal Range: 6-9%
- Elevated Moisture: 9-13%
- High Moisture: 13%+
Consequences of Excessive Moisture
Excessive moisture can lead to:
- Mold growth, which can cause respiratory problems and allergic reactions
- Structural damage, weakening the wall’s integrity
- Reduced insulation effectiveness, increasing energy costs
Moisture Detection and Mitigation
To detect moisture, non-invasive moisture meters are used. If elevated or high moisture levels are detected, immediate action is required:
- Identify the source of moisture (e.g., leaks, condensation)
- Repair the source and address any underlying issues
- Ventilate the affected area to reduce moisture buildup
- Consider using dehumidifiers or air conditioners to control humidity levels
Conclusion
Maintaining optimal moisture levels in internal walls is essential for ensuring a healthy and structurally sound environment. Monitoring and addressing elevated moisture levels promptly can mitigate damage and maintain the integrity of the building.
