Fixed Fire & Smoke Curtain
A Fixed Fire & Smoke Curtain, also known as a fixed draft curtain, contains smoke within a defined area and prevents it from spreading to adjoining sections of a building. Unlike automatic curtains that deploy on alarm, fixed curtains remain permanently in position, acting as a static smoke barrier at all times. See our full Fire & Smoke Curtains range for automatic and accordion options.

Fixed Curtain Features
- Permanently positioned — no activation mechanism required.
- Overlapping curtain panels joined into a single continuous run.
- Panels connected via clamps and angle pieces to the building structure.
- Weighted bottom hem keeps the curtain taut, resisting deflection from air currents.
- Lightweight alternative to steel sheeting for the same containment role.
- Manufactured to suit custom shapes and sizes for the application.

How a Fixed Fire & Smoke Curtain Works
Fixed fire curtains are built from multiple overlapping panels rather than a single sheet, allowing long, continuous runs to be assembled across large roof spans. Each panel connects to the next, and the full run is fixed to the building structure using clamps and angle brackets. A weighted hem along the bottom edge keeps the fabric hanging straight and taut, so it holds its containment line even when air currents from ventilation, machinery, or vehicle movement would otherwise cause it to sway.
Because the curtain is fixed rather than motorized, there is no descent mechanism, control panel, or fire-alarm trigger involved — the barrier is simply always in place, doing its job continuously. This makes it a straightforward, low-maintenance option for spaces where a permanent smoke reservoir boundary is more practical than a retractable curtain.
Applications
Fixed fire curtains are best suited to large, open-volume spaces where the barrier can remain permanently in position without obstructing daily operations — most commonly aircraft hangars and warehouses. In both settings, the curtain divides the roof space into smoke reservoirs, giving smoke extraction systems a defined zone to work within during a fire, rather than allowing smoke to spread unchecked across the entire structure.
