What is one of the functions of fire-resistant drywall?

Fire-resistant drywall plays a crucial role in fire protection by helping to contain and retard the spread of fire. This type of drywall is specially formulated with materials that improve its fire-resistance rating, which is essential in building codes and safety regulations. By delaying the heat transfer and resisting ignition, fire-resistant drywall provides vital time for occupants to evacuate and allows firefighters to control the blaze more effectively.

Its design includes the addition of glass fibers and other components, contributing to its ability to withstand high temperatures for an extended duration compared to standard drywall. In residential and commercial buildings, this property is especially relevant in areas where the risk of fire spread is a significant concern, such as between units in multi-family dwellings, in stairwells, or around mechanical spaces.

While the other options all describe attributes that may be associated with building materials, they do not specifically relate to the primary function of fire-resistant drywall, which is to enhance fire safety by containing fires and preventing their rapid spread.
