What must windows in smoke partitions be designed for?

Windows in smoke partitions serve an essential role in maintaining the integrity of smoke control systems within a building. They must be designed specifically to manage the flow of smoke during a fire event, which is why they can be either sealed to resist the passage of smoke or automatic-closing upon smoke detection.

The purpose of sealing windows is to prevent smoke from migrating from one area to another, thereby protecting occupants and allowing for safe evacuation. Similarly, automatic-closing mechanisms are designed to engage when smoke is detected, further aiding in the containment of smoke.

Having the flexibility in design (either sealed or equipped with automatic-closing features) provides building designers and inspectors clarity on how to approach smoke partition window installation based on the building's unique requirements and fire safety strategies. This dual option allows for tailored solutions that can be more effective in managing smoke control along with ensuring compliance with safety regulations.
