Edge-of-slab fire barrier systems for single spandrel, zero spandrel, and steel back pan configurations

Generally, the model building codes require the void between a rated floor assembly and a non-rated exterior wall, such as a curtain wall, shall be protected by a listed firestop system.  But, the complexities of modern-day façades are pushing the limits of fire safety and forcing manufacturers to develop innovative firestop solutions to solve today’s design challenges.

Where unique designs demand customized solutions, Hilti’s extensive firestop experience, in conjunction with a comprehensive firestop systems portfolio, enable us to provide the right solutions to meet your project specific perimeter firestopping needs.
