Moisture-resistant gypsum board: where to use it
Moisture-resistant gypsum board has water-repellent additives in the core and facing, so it swells, sags and grows mold far less than standard board in steamy or humid rooms. Use it for drywall ceilings, T-bar ceilings and partitions, but keep it out of direct water.
