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.
