There are two materials used for this purpose: fiberglass and a wax coating over a slightly thicker paper face. It’s the facing material that makes the difference. Gypsum is a mix of calcium sulfate dihydrate and water, and these materials are pressed into long, rigid sheets before being covered with paper facing, fiberglass mesh, or wax-embedded paper. Mold-resistant drywall contains the same core as standard drywall, made from non-organic, non-combustible gypsum. Even if the surface of the drywall becomes damp due to moisture or humidity within the room, mold can’t embed or feed on this type of drywall. Mold-resistant drywall works by creating an inhospitable environment for mold. ![]() Should a leak or high humidity condition occur in those areas, the added cost may be worth it. While this is an added expense, it’s only necessary to install mold-resistant drywall in certain areas and rooms within the home, such as bathrooms and laundry rooms-areas with the potential for a lot of humidity. In general, mold-resistant drywall costs roughly 30 to 50 percent more than a sheet of standard drywall. This differs from standard drywall which has a paper face-just the sort of organic material mold thrives on. This material prevents mold spores from attaching and embedding themselves in the wallboard, and doesn’t provide the organic material mold requires to spread. ![]() Mold-resistant drywall is a building material composed of a gypsum core and a non-organic facing material. $75.00 USD | 55M Preview Course What is mold-resistant drywall? ![]()
