Which material can serve as an effective fire-resistive construction material?

Gypsum board is recognized as an effective fire-resistive construction material due to its inherent properties that provide a barrier to heat and flames. The core composition of gypsum board includes gypsum, a mineral that is naturally fire-resistant. When exposed to fire, the water content within the gypsum will help provide a cooling effect and delay the spread of flames, which keeps the underlying structure protected for a considerable amount of time. This property makes gypsum board an essential component in building codes aimed at enhancing fire safety.

In construction, gypsum board is commonly used for walls and ceilings in areas that require fire-rated assemblies, thus contributing to the overall fire resistance of buildings. Its versatility and effectiveness in fire resistance stand out in comparison to the other materials listed, which do not offer similar protective characteristics against fire.
