Determining the moisture levels in internal walls is crucial for maintaining optimal indoor air quality. Ideal moisture content helps prevent mold growth, which can trigger respiratory issues and other health concerns.
Understanding Moisture Readings
Moisture readings are expressed as a percentage of weight compared to the wall’s oven-dried weight. Desirable moisture levels for internal walls vary based on the material:
| Wall Material | Acceptable Moisture Content (%) |
|---|---|
| Plasterboard | 10-15 |
| Timber | 12-18 |
| Concrete | 4-8 |
Effects of Excessive Moisture
Excessive moisture in walls can result in:
- Mold growth and its associated health risks
- Damage to the wall’s integrity, leading to structural issues
- Reduced indoor air quality, affecting occupant well-being
Controlling Moisture Levels
Maintaining proper ventilation, using dehumidifiers, and addressing leaks can help control moisture levels. Regular moisture readings by qualified professionals ensure early detection of any problems, enabling timely intervention.
