Fire-rated exterior wall assemblies are specifically designed to resist the spread of fire from one area of a building to another. They act as barriers, preventing the fire from rapidly spreading and giving occupants sufficient time to evacuate the premises. These assemblies are constructed using fire-resistant materials and are subjected to rigorous testing to ensure their effectiveness.
The term 1-hour fire-rated refers to the duration for which the assembly can withstand the spread of fire. In the event of a fire, this type of assembly can contain the flames for at least one hour, providing valuable time for people to escape and for firefighters to arrive at the scene. The materials used in the assembly, such as fire-resistant gypsum boards and fire-rated insulation, play a crucial role in achieving this level of fire resistance.

One of the key components of a 1-hour fire-rated exterior wall assembly is the fire-rated gypsum board. These boards are made of special gypsum cores that contain glass fibers and other additives to enhance their fire resistance. They are installed over metal or wood studs to create a protective layer that slows down the spread of fire. The gypsum boards also help to maintain the structural integrity of the wall during a fire, preventing it from collapsing and creating further hazards.
Another important element in a 1-hour fire-rated exterior wall assembly is the fire-rated insulation. Insulation materials with fire-resistant properties, such as mineral wool or fire-resistant foam, are used to fill the cavities between the wall studs. This insulation not only improves the overall energy efficiency of the building but also acts as a barrier to prevent the fire from penetrating through the wall assembly.
