What does the term "green board" refer to in drywall?

Standard drywall used for ceilings
Moisture-resistant drywall used in high-humidity areas
Fire-resistant drywall for kitchens
Insulated drywall for soundproofing

The correct answer is: Moisture-resistant drywall used in high-humidity areas

The term "green board" specifically refers to moisture-resistant drywall that is designed for use in high-humidity areas, such as bathrooms and kitchens. This type of drywall is coated with a green paper that enhances its resistance to moisture compared to standard drywall, making it less susceptible to mold and mildew growth. Placing green board in environments that experience high moisture not only helps to protect the integrity of the wall but also contributes to improved indoor air quality by reducing the potential for mold development. This specialization is crucial in drywall applications where excessive moisture could lead to significant structural and health issues over time. Other options do not accurately describe the characteristics of green board. Standard drywall does not have moisture resistance; fire-resistant drywall is formulated for fire hazards, and insulated drywall is meant for soundproofing or thermal insulation rather than moisture resistance.
