DSI-H 3HR Horizontal Fire Curtain


The DSI Horizontal Fire Curtain Model DSI-H3HR allows architects to compartmentalize large floor openings and reduce or eliminate mechanical smoke evacuation systems. A solution to design challenges of preventing smoke and fire from spreading through the ceiling and atrium voids, stairwells, and skylights.

The DSI Horizontal Fire Curtain consists of a light gauge steel headbox that houses the roller, fabric, and motor within the casing to create a small compact package that remains virtually invisible. The curtain consists of woven fiberglass wire reinforced fabric. During deployment, the slim steel side guides prevent derailment of the fabric during operation ensuring integrity of the system when faced with negative or positive pressures of a fire.
