Automatic Smoke Curtains

Motorised smoke curtains contain and channelise smoke in the critical early stages of a fire - protecting escape routes, maintaining visibility and directing smoke towards extraction units. Gravity fail-safe deployment as standard.

Forming the reservoir

Smoke curtains subdivide large volumes, channel smoke toward extract points and keep escape routes clear in the critical early stages of a fire - when visibility and tenability matter most.
