Summary: Mold in your home can cause health problems. Mold Resistant Drywall can help prevent mold.
In recent years, there has been a growing concern about mold.
Today’s homes are more airtight, thereby trapping more pollutants, like mold spores. Mold spores are microscopic airborne particles.
Eliminating mold can be not only very difficult, but very expensive.
It is better to try and prevent the growth of mold through mold prevention.
As they say, “An ounce of prevention is worth a pound of cure”.
Mold is a living organism and it needs food and moisture to live.
Take away one of the two, and you help prevent mold.
Drywall manufacturers have found that gypsum board with paper facings (drywall) can absorb moisture, so they have developed mold resistant gypsum.
It won’t absorb moisture as easily as regular drywall, thus taking away one of the essentials that mold needs to survive.
Mold Resistant Drywall only limits the conditions which are necessary for organism growth, thus reducing the chances for mold.
Mold-resistant does not mean that mold cannot grow. Under the right conditions, mold can grow on almost any surface.
