Moisture mapping provides a thorough assessment of moisture distribution within a structure. Understanding the acceptable moisture levels is crucial for preventing structural damage and potential health hazards.
* For most building materials, including drywall, an acceptable moisture content range is between 5% and 15%.
* Drywall becomes damaged when moisture exceeds 20%.
* Excessive moisture can lead to warping, swelling, and delamination of the drywall panels.
Mold is a common problem associated with excessive moisture in buildings. Mold typically starts to grow when moisture content reaches above 60%.
Drywall, in particular, is susceptible to mold growth due to its high cellulose content. Mold spores are always present in the air, and when they land on a moist surface, they can germinate and start to grow rapidly.
Therefore, maintaining moisture levels below 60% in drywall is essential to prevent mold growth and potential health issues associated with mold exposure.
