Firestopping Needs in a Commercial Building

摘要

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.
