Total passive fire protection cannot be achieved with the use of a singular product. It is the use of many products designed for specific applications that comprise a complete passive fire protection system. When installed properly, these products work in concert with one another to create effective barriers against the passage of flames, smoke, and superheated gases. Used in conjunction with other fire protection methods, properly installed passive fire protection will save lives, protect property, and minimize business losses.

Firestop is a product that, when installed properly, impedes the passage of fire, smoke, and toxic gases from one side of a fire-rated wall or floor assembly to another. Typical firestop products include sealants, sprays, mechanical devices (firestop collar), foam blocks, or pillows. These products are installed primarily in two applications:

1) around penetrations that are made in fire-resistive construction for the passage of pipes, cables, or HVAC systems, and

2) where two assemblies meet, forming a expansion joint such as the top of a wall, curtainwall (edge of slab), or floor-to-floor joints.
