Green gypsum is specifically used in bathrooms because it is __________.

Green gypsum board, commonly referred to as moisture-resistant drywall, is particularly designed for environments that experience high humidity levels, such as bathrooms. This type of board is treated to prevent mold growth and withstand damp conditions, making it ideal for areas exposed to water or moisture. Bathrooms frequently encounter steam from showers and water splashes, which can easily damage standard drywall over time.

By using moisture-resistant green gypsum, contractors ensure that the material maintains its integrity and longevity in these challenging conditions. It is important for residential construction to select appropriate materials that enhance durability and safety in specialized environments, thereby extending the life of the structures and minimizing maintenance issues associated with moisture damage.

Other types of drywall may have different properties, such as fire resistance or lightweight characteristics, but these do not specifically address the moisture concerns prevalent in a bathroom setting. Thus, the correct choice highlights the unique feature of green gypsum that makes it suitable for such applications.
