What does the term “non-combustible” refer to in construction materials?

In the context of construction materials, "non-combustible" refers to materials that are not able to ignite or support combustion under typical conditions. This characteristic is critical for enhancing the fire safety of a building, as non-combustible materials do not contribute to the spread of fire. Common examples include concrete, steel, and brick, which can withstand high temperatures without igniting or sustaining flames.

When utilizing non-combustible materials, architects and builders can reduce the risk of fire-related damage and improve the overall safety of the structure. Fire codes and standards often require that certain building elements, such as exterior walls, floors, and ceilings, be made of non-combustible materials to ensure public safety and limit the potential for fire hazards in buildings.
