Overview
In the event of a fire, a standard fire shutter can become red hot when exposed to intense flame. Such extreme heat can radiate through the shutter potentially igniting nearby combustible materials. This can allow the fire to spread well beyond it’s point of origin.
Solution? An Insulated Fire Shutter.
Unlike standard fire shutters, the insulated model is designed to reduce the transmission of radiant heat, providing another layer of protection to prevent the spread of fire making them an essential barrier in environments where flammable or heat sensitive materials are stored.
Insulated fire shutters provide:
Dual-sided Fire Insulation – Steel slats on both sides provide insulation against fire attacks from either direction.
Robust and Impact Resistant – Can function as a security shutter and built for daily use.
Weather Resistant – Suitable for external applications, with PVC bottom seal to protect against the elements.
Pressure Resistant – The rigid design accommodates differences in air pressure from ventilation systems.
Self-Supporting Structure – Steel guides transfer most of the shutters weight to the floor, reducing structural load.
Rapid Closure – Can be configured to close within 30-60 seconds, depending on site requirements.
Applications:
- Dangerous Goods Stores
- Warehousing
- Storage Facilities
- Manufacturing Plants

Drum Assembly
The barrel assembly consists of an extremely rigid steel tube sheathed over a pair of drive shaft assemblies fitted to heavy duty bearing sets and supported at both ends by steel head plates. The drive shaft is a solid polished steel round bar incorporating key ways to accept the drive sprocket. Corresponding to the size of the shutter, the head plates are either 6mm or 8mm thick with shafts of either 38mm or 50mm diameter.
The entire drum assembly is enclosed by a housing consisting of 1.0mm thick galvanized steel sheet cladding secured over an insulation layer of fire boards.
The IFS-4G incorporates a self-supporting structure in the form of a ‘goalpost’ made up of steel ‘C’ channels. The entire shutter box and barrel assembly rests on this structure, thereby transferring the bulk of the weight to the floor. The head plate is then anchored to the wall to secure the shutter vertically.
Curtain
The curtain is formed by a single layer of interlocking steel cavity slats spanning the full width of the door opening.
Slat
Each slat consists of a continuous length of an inner and an outer steel profile. They are connected back-to-back by modular stud brackets without the use of any exposed fasteners. This unique design secures the two profiles together while keeping them thermally separated. The cavities between the profiles are filled with insulation material, creating a dense, energy-efficient core.
End Clips
Custom-shaped steel end-clips are secured to the ends of the slat to prevent lateral movements and ensure structural stability.
Bottom Rail
The bottom rail is constructed from two lengths of 50mm x 50mm x 2.0mm thick steel angles, secured back-to-back through a medium of fire boards. A PVC weather seal covers over the fire boards and forms a tight seal against the floor when the shutter is fully closed.
Guides
The door guides are a pair of modules formed by fire boards built around the steel ‘C’ channel vertical guide posts. The rear face of each guide module is finished with galvanized steel cladding for added durability and a clean appearance.
Operation
The drive unit consists of a suitably-sized linear drive motor operator, mounted parallel to and behind the door roll. It has an integrated gearbox and a chain operated sheave wheel for manual operation in case of power failure.
The control box is lockable, housing a set of push buttons for Up’, ‘Down’ and ‘Stop’ operations. The door operation shall automatically stop at the desired upper and lower limits via adjustable limit switches. For safety reasons, the ‘DOWN’ button shall require the operator to push and hold when closing the shutter. This is to ensure the closing operation is being supervised.
Upon sighting an obstruction, the operator will automatically release the push button by reflex. This action will instantly stop the downward travel of the shutter and prevent accidents.
Power supply requirement: 3 Phase 415V x 20amp isolator to be provided for each motor.
Activation
The motor operator has a versatile control adaptability that can enable it to respond to a wide range of activation modes, including Fire Alarm signal, smoke or heat detectors, fusible links etc. In certain situations, a fail-safe operating configuration may be required. This is available as an option.
