Green gypsum board is specifically used in bathrooms due to its what property?

Green gypsum board, commonly known as moisture-resistant or water-resistant gypsum board, is specifically designed for use in areas prone to high humidity, such as bathrooms. Its key property is moisture resistance, which enables it to withstand damp conditions without the risk of warping, mold growth, or other moisture-related damage that can occur with standard gypsum board.

This moisture-resistant formulation typically includes additives that enhance its ability to repel moisture and prevent it from penetrating the board. This makes it an ideal choice for wet environments where showers, sinks, and other sources of water can create a humid atmosphere.

The other properties mentioned, such as fire resistance, acoustic properties, and thermal insulation, serve different functions and are not the primary focus of green gypsum board. Fire-resistant boards are designed for increased fire safety, acoustic boards aim to minimize sound transmission, and thermal insulation is primarily concerned with temperature regulation. Therefore, while these properties are important in their own contexts, they do not contribute to the specific reason why green gypsum board is used in bathrooms.
