According to IBC Section 404.6, atrium spaces shall be separated from adjacent spaces by a 1-hour fire barrier constructed in accordance with Section 707 or a horizontal assembly constructed in accordance with Section 711, or both.
Smoke and Fire curtains are used for smoke containment and smoke compartmentalization in atria as part of an engineered smoke control system. Smoke curtains can be used as a component in exhaust or pressurization smoke control systems and additionally provide a 1-hour or 2-hour fire rating.
Atrium smoke control is complex and requires close coordination between the curtain manufacturer, the fire protection engineer, the mechanical engineers, the architect, and the AHJ. We provide design and code compliance support free of charge.
