A new publication from the International Code Council and the International Firestop Council examines provisions related to the protection of openings and penetrations in fire-resistance-rated construction to preserve the effectiveness of the rated assembly. The book explains and illustrates the correct application of the code requirements so that a fire-resistance-rated and/or smoke-resistant building assembly can perform as intended and maintain its rating. It describes the important differences between these devices and systems, exactly how and where they are used, and code-compliant installation.
