Vertical Kent Defender Fire Curtain

Updated: May 4, 2022

Vertical Fire Curtains are life safety systems that are designed to arrest the spread of fire in a building. The assembly comprises a fire-resistant fibreglass fabric wound over a roller and all encased in a compact headbox that is typically installed above the ceiling to be virtually invisible until activated. When activated by either a general fire alarm or a local detector, the fire curtain descends from its holding position within the headbox to its operational position (floor level) and thus forms a physical barrier for fire compartmentalization. Using the Defender K Gravity Fail-Safe System, our fire curtains descend without the need for power and fail to safe systems. These fire curtains have enabled large open building designs where otherwise permanent fire-rated partitions would be required. ​MAXIMUM WIDTH:
