What is a Fire-Rated Wall?

What Comprises a Fire-Rated Wall?

Designed to contain fire and smoke for a predetermined amount of time, fire-rated walls are part of a building’s passive fire protection system. Whether permanent or temporary, these walls are inspected against applicable code by the appropriate regulatory authorities, with the goal of preventing fire from spreading from one part of a building to another. The wall’s rating indicates how long it can contain the fire – typically 45 or 90 minutes, or 1-, 2- or 4-hours. For more information about one-hour fire-rated temporary containment walls, click here.
