During a fire, a deployed fire shutter can become extremely hot, and the intense heat radiating from the shutter curtain may ignite combustible materials on the other side, allowing the fire to spread.
Fire containment starts with proper insulation. Most fire codes permit fire shutters to serve as compartment walls, but only if they are insulated. In areas storing highly combustible materials, insulation is essential to prevent fire from spreading through radiated heat.
Our fire-insulated roller shutters help prevent the spread of fire and radiated heat, protecting both people and property.
Even under intense flames, the insulated curtain safeguards combustible materials, providing effective heat containment.

Our insulated fire roller shutter solutions are engineered to meet demanding fire-protection requirements, with the IFS-4G offering a self-supporting steel-curtain design that minimises heat transfer, provides structural stability, and supports daily operational use.
Each model is purpose-built to minimise heat transfer, provide structural stability, and support daily operational use.
The Gliderol IFS-4G is our latest 4th-generation design, featuring steel curtains, slats, and a self-supporting design to withstand high temperatures while minimising heat transfer to adjacent areas.
Download BrochureThe IFS–4G has been tested to internationally recognized safety standards, including BS EN 1634-1 2014 + A1 2018, EN 1634-1 2014, SS 489:2015, MS 1073:1993, and TCVN 9383:2012.
It is available in three models, each offering different levels of fire insulation.
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 keyways to accept the drive sprocket.
Corresponding to the size of the fire-insulated roller 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 thk 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 ‘goal-post’ 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.
Door Curtain
For IFS-4G, the shutter curtain is formed by a single layer of steel interlocking cavity slats spanning the entire width of the door opening.
Door Curtain Material
Slats
For IFS-4G, 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 voids between the two profiles are filled with insulation material to form a dense core.
The internal surfaces of the slats are lined with an insulation blanket comprising mineral wool and fire-resistant fabric. The blanket is securely attached to the slats in an innovative way, without puncturing the insulation materials with fasteners.
End Clips
Custom-shaped steel end-clips are secured to the ends of the slat to prevent lateral movements.Bottom Rail
The bottom rail is formed by 2 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 the fire boards and seals against the floor when the shutter is fully closed.
Door Guides
The door guides are a pair of modules formed by fire boards built around the steel ‘C’ channel vertical guide posts. The back of the guide module is finished with galvanized steel cladding.
The steel ‘C’ channel guide posts also act as vertical structural supports by helping to transfer the fire-insulated roller shutter weight to the floor.
Finishes
Available in Stainless Steel, Galvanised, Polyester Pre-coated, Powder-Coated, or PVF2 finishes.
Door Operation
Motor Drive
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 a power outage.
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.
Inevitably, the curtains of all fire-insulated roller shutter designs are quite heavy, exceeding the capacities of conventional shutter operators.
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 20-amp isolator to be provided for each motor.
Fire 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.
