Which material is considered essential in the design of fire-resilient buildings?

The design of fire-resilient buildings prioritizes materials that can withstand high temperatures and resist ignition. Non-combustible materials, such as concrete, steel, and masonry, play a crucial role in enhancing fire resistance. These materials do not ignite or contribute to the spread of fire, thereby providing structural stability and reducing the overall risk associated with fire incidents.

Using non-combustible materials helps to create fire barriers and compartments, which can slow down the spread of flames and smoke, offering occupants more time to evacuate and enhancing the safety of firefighters. Additionally, building codes and regulations often specify the use of non-combustible materials in certain areas, particularly in high-risk environments or buildings with strict fire safety standards. This is why the answer emphasizes the importance of non-combustible materials in the context of fire resilience in building design.
