What should moisture readings be for internal walls

When assessing the performance of building interiors, moisture readings are crucial indicators. Internal walls should ideally maintain moisture levels within specific ranges to prevent structural damage, mold growth, and health concerns.

What Should Moisture Readings Be for Internal Walls?

The acceptable moisture content for internal walls varies depending on the material used. Here are typical moisture readings:

Wall Material Moisture Reading
Plasterboard < 15%
Gypsum < 10%
Concrete < 8%
Brick < 10%
Wood < 12%

Consequences of Excessive Moisture

  • Structural damage (cracking, warping)
  • Mold growth
  • Poor indoor air quality
  • Health issues (respiratory problems, allergies)

Monitoring Moisture Levels

Regular monitoring of moisture levels is essential to ensure optimal wall performance. Moisture meters are used to measure the moisture content of walls by inserting probes into the material.

Importance of Proper Moisture Control

Maintaining appropriate moisture levels is vital for several reasons:

  • Preserves structural integrity
  • Prevents mold formation
  • Ensures a healthy indoor environment
  • Extends the lifespan of the building

By understanding the recommended moisture readings and implementing proper moisture control measures, building owners and managers can ensure the performance and longevity of their buildings.
