Buildings are constructed using materials with varying resistance to fire. Fire-resistant construction designs are employed to prevent the spread of fire and protect occupants and property. Fire-resistant materials are rated based on their ability to withstand fire for a given duration, usually expressed in hours.
Fire ratings are determined based on standardized fire tests conducted by accredited laboratories. These tests measure the time it takes for a material or assembly to reach certain failure criteria, such as:
Various materials offer differing levels of fire resistance, including:
Fire-resistant building practices offer several advantages:
Fire-resistant construction is essential for creating structures that can withstand fire and protect occupants and property. By using materials with appropriate fire ratings and employing proper fire protection measures, buildings can be designed to be more resilient to fire damage.
