What is the purpose of using a moisture-resistant board in specific areas?

The purpose of using a moisture-resistant board in specific areas is primarily to enhance moisture resistance. These boards are designed to resist moisture absorption, which helps prevent issues such as mold growth, warping, and structural damage that can result from prolonged exposure to humidity or water.

Moisture-resistant boards are often utilized in areas that are prone to high humidity, such as bathrooms, kitchens, and basements, where traditional materials might deteriorate over time when exposed to moisture. By incorporating these boards into construction, builders ensure the longevity and durability of the structure while maintaining a healthy indoor environment.

The other options, such as preventing fire hazards, reducing sound transmission, and increasing thermal insulation, highlight important considerations in construction but do not directly relate to the primary function of moisture-resistant boards.
