Introduction

Molds are fungi that can grow on damp surfaces, including drywall. Mold growth can be prevented by maintaining an attic that is dry and well-ventilated.

What Moisture Level Does Mold Grow in Drywall?

Mold can grow in drywall when the moisture content is above 15%. This can occur due to:

– Condensation from humid air
– Leaks from roofs or plumbing
– Flooding
– Poor ventilation

Attic Ventilation and Mold Prevention

Proper attic ventilation is essential for preventing mold growth in drywall. Ventilation helps to remove moisture from the attic, which helps to keep the drywall dry. There are two main types of attic ventilation:

Natural Ventilation

Natural ventilation relies on the movement of air through vents in the attic. These vents can be located in the soffits (under the eaves of the roof) and/or in the gable ends (the triangular ends of the roof).

Mechanical Ventilation

Mechanical ventilation uses fans to move air through the attic. These fans can be installed in the soffits, gable ends, or roof ridge.

Conclusion

Mold growth in drywall can be prevented by maintaining an attic that is dry and well-ventilated. Natural ventilation and/or mechanical ventilation can be used to remove moisture from the attic and help to keep the drywall dry.
