In areas with high moisture, such as bathrooms, green board or moisture-resistant drywall is the appropriate choice. This type of drywall is specifically designed to withstand increased humidity and moisture levels better than regular drywall. It has a special moisture-resistant core and is typically faced with a green paper that helps to reduce water absorption.

Using green board in moisture-prone areas helps prevent mold and mildew growth, which is crucial for maintaining a healthy indoor environment. Regular drywall lacks these moisture-resistant properties and would deteriorate more quickly in humid conditions. Fire-resistant drywall serves a different purpose, focusing primarily on providing fire resistance and not on moisture issues. Paper-faced drywall is a general term that applies to standard drywall and does not offer the same level of protection against moisture. Therefore, green board is the ideal choice for areas such as bathrooms.
