Smoke curtains and fire shutters are both fire protection systems, but they serve different purposes and function differently in a building’s fire safety strategy. Here are the key differences between them:


  • Smoke Curtain:

    • Primarily designed to control and contain smoke during a fire.

    • Helps to prevent the spread of smoke to other areas, improving visibility for evacuation and reducing smoke inhalation risks.

    • Typically used in conjunction with smoke ventilation systems to manage smoke movement within a building.

  • Fire Shutter:

    • Primarily designed to provide a physical barrier to stop the spread of fire.

    • Can also help in containing smoke to some extent, but their main function is to contain and compartmentalize fire.

    • Often used to protect openings in fire-rated walls, such as doorways, windows, or service counters.

Construction and Materials

  • Smoke Curtain:

    • Made from flexible, fire-resistant materials that can withstand high temperatures but are lightweight.

    • Often consists of a fabric curtain that can be deployed vertically or horizontally.

  • Fire Shutter:

    • Made from more rigid, fire-resistant materials such as steel or other metals.

    • Typically resembles a rolling shutter or door that can be rolled down or across an opening.


Activation and Operation

  • Smoke Curtain:

    • Automatically deployed upon detection of smoke or fire, often triggered by smoke detectors or fire alarm systems.

    • Can retract or deploy to create smoke reservoirs or direct smoke towards exhaust systems.

  • Fire Shutter:

    • Automatically activated in response to heat or fire detection, such as through the building’s fire alarm system or a fusible link that melts at a certain temperature.

    • Closes to seal off an area and maintain fire compartmentalization.

Installation and Use

  • Smoke Curtain:

    • Commonly installed in open spaces, atriums, stairwells, and corridors to control smoke flow and maintain escape routes.

    • Can be used in conjunction with glass walls or partitions to provide an invisible barrier against smoke.

  • Fire Shutter:

    • Typically installed in walls, doorways, and windows to provide a fire-rated barrier.

    • Used in areas requiring high fire resistance, such as between different fire zones or in places where fire doors are impractical.

Regulations and Ratings

  • Smoke Curtain:

    • Generally tested and rated based on smoke leakage performance and temperature resistance.

    • May need to comply with specific smoke control standards and regulations, which can vary by region.

  • Fire Shutter:

    • Tested and rated based on fire resistance, typically measured in hours (e.g., 1-hour, 2-hour fire rating).

    • Must comply with fire safety regulations and building codes that specify the required fire rating for different applications.

In summary, smoke curtains are designed to manage smoke movement and maintain clear escape routes, while fire shutters provide a robust barrier to prevent the spread of fire and maintain fire compartmentalization within a building.
