In many cases the building must be designed with a fire-rated floor system. This typically means that the cavity between the edge of the floor slab and the back of precast within the SlenderWall system needs to incorporate a fire-stop or other fire safety design. This cavity is filled with a mineral-wool fireproof material. A pourable smoke seal material may or may not be used on top of the fire-stop material.

There are several UL rated assemblies utilizing proprietary fire safety material that can be used to provide the required fire safety design. Refer to Drawing Detail A-3 in the Typical Details for typical Fire Stop detail at slab edges.
