Fire Rated Walls: Types, Assemblies, and Code Requirements

Fire rated walls are tested and certified wall assemblies that buy precious time during a fire emergency. This episode breaks down how fire rated wall assemblies actually work, from the science behind Type X gypsum board to UL assembly specifications and firestopping requirements. You'll learn the difference between 1-hour and 2-hour fire rated walls, when building codes require each type, and the common mistakes that compromise fire rated wall construction.
