Building Façade Fire Protection
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.
