Insulated Fire Roller Shutter (IFS) Partner with Gliderol

Certification: MS1073:PART3 & BS476:PART22


IFS-2G Series Fire Insulated Shutters

In a fire situation, a deployed fire shutter can turn red-hot when subjected to the full force of the flames, and intense heat can radiate from the shutter curtain. This radiated heat can ignite combustible materials that may be stored on the other side, hence allowing the fire to spread. The solution to this is the use of Fire Insulated Shutters.


Most fire codes permit fire shutters as compartment walls, but they need to be insulated. 


In premises where highly combustible materials are stored, the fire shutters should also be insulated. The objective is to prevent the spread of fire through heat radiation effectively.


The IFS-2G has the following features:-


  • The asymmetrical design provides fire insulation for fire attacks from any direction. This is a necessary criterion if used as a compartment wall

  • Steel slats on both exposed curtain surfaces – for durability and impact resistance

  • Suitable for use as an external shutter, with PVC bottom weather seal

  • Can double-up as a security shutter for daily usage

  • Rigid curtain – can accommodate air pressure differentials from mechanical vents

  • Do not need guide encasements (unlike most insulated fire shutters)

  • Can meet any regulator-prescribed closing speed (e.g., 10 to 30 secs for Malaysia & Singapore) Watch Video Below

  • Fail-safe model available where required.

  • DfMA friendly – can be supplied fully-assembled for easy incorporation into any PPVC module.

We have 2 models, all with maximum Width of 12.0m & max Height of 7.0m :

  • IFS-2G 60 offers 60 mins of fire insulation with fire integrity of up to 240 mins

  • IFS-2G 120 offers 120 mins of fire insulation with fire integrity of up to 240 mins


Door Curtain

The door curtain consists of two walls of steel interlocking slats that are attached to a single barrel such that they roll and unroll as one. The slats of each wall are faced away from the other, with the concave faces forming the exposed surfaces of the walls. Model IFS-2G 240 has two such curtains rolled unto two separate barrels, with an air-gap in between.

Door Guides

The slats are specially-designed interlocking profiles that are roll-formed from galvanised steel material of various thicknesses.

The internal surfaces of the slats are lined with an insulation blanket comprising of 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.

Custom-shaped steel end-clips are secured to the ends of the slat to prevent lateral movements.

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 thk galvanized steel sheet cladding secured over an insulation layer of fire boards.

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 over the fire boards and seals against the floor when the shutter is fully closed.

The door guides are a pair of modules formed by fire boards built around the steel ‘C’ channel vertical guide posts. The surround 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 shutter weight to the floor. 

Door Operation

Motor Drive

Inevitably, the curtains of all insulated fire shutter designs are quite heavy, exceeding the capacities of conventional shutter operators. As such, the IFS-2G employs a custom-built motor operator to manage the weight of its two walls of insulated steel curtain. 

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 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.

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.

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.

It incorporates an effective controlled-descent governor that allows large shutters to close safely by gravity while achieving the prescribed closing time. This is one of the most important criteria of the custom-built operator.

Where a fail-safe operating configuration is required, the IFS-2G can be fitted with a fail-safe motor operator that has a system-monitoring capability. It ensures the automatic closure of the shutter whenever there is a power outage or a fault in any of the fire activation devices.
