Fire Shutters

Fire shutters and smoke curtains are usually used as part of an overall fire strategy in a building used in conjunction with other systems for controlling fire such as sprinklers and smoke extraction systems. All fire protection systems react to fire, heat and smoke in different ways in order to keep the building safe for occupants and emergency services in case of a fire. The role of the Fire shutter or smoke curtain is to compartmentalize a building in order to help prevent the fire from spreading so rapidly allowing anybody inside to evacuate as safely as possible. We have supplied these doors to a diverse range of customers including shopping centres, hospitals, school canteens, restaurants – as well as numerous clients in the industrial sector. Our fire-rated roller shutter doors and smoke curtains can be supplied with either a 1, 2, or 4 hour fire rating, depending on your requirements, and are tested to BS476 part 22: 1977. We offer a single skin and twin skin insulated fire shutter, depending on your needs and budget, as well as a fire curtain option for increased aesthetics and better protection against smoke.


This model FR – 78INS model provides incredible radiant heat protection. To put this into perspective, normally if a fire was raging at 1200oC on the other side of a standard fire shutter you wouldn’t be able to stand within 6 metres of the opening. However, due to the FR-INS4H’s unique construction, the radiant heat levels around the roller shutter door drop from 65kw sq metre to an incredible 2.7 kw sq metre. The FR – 78INS also offers a sound reduction value meaning they are good to use in kitchens where the room next door may also used for meetings or exhibitions. These fire-rated doors are fitted with safety brakes, coupled with ‘drive ratio control’, in order to manage controlled descents. Furthermore, we can incorporate one of our interface panels so that the roller shutter closes automatically when the fire alarm is set off.

  • The curtain is normally constructed from laths comprising a Galvanize material outer skin bonded to a special inner core consisting of high performance insulation materials.
  • Stainless steel cables connected the laths together and are fastened to the roller at the head.
  • The bottom rail comprises a standard lath fitted with an extruded PVC bottom seal.
  • Guides Manufactured from galvanised steel and shaped into a channel profile which is prepared for bolting to the structure by means of continuous fixing angles.
  • Endplates
  • Manufactured from galvanised steel of adequate thickness relative to door size and supplied with steel plates for fixing to the structure.
  • Head
  • A combination of galvanised steel and ‘u’ profile and MDF board with a special fire protection cover fastened to the lintel into which the top of the door engages providing an effective seal against the passage of flames and hot gasses.
  • Barrel
  • The barrel comprises a steel tube of suitable diameter and wall thickness to avoid deflection. Steel shafts and discs are inserted at each end and the whole assembly is supported at each end on the end brackets.
  • Operation
  • Our Fire rated shutters are typically installed with an induction motor, an electromagnetic brake, limit switches and a fusible link. The design provides a reliable system that will close the shutter automatically in the event of a fire situation. A controlled descent comes as an inbuilt safety feature.
  • In the event of a power loss, manual operation can be attained. By releasing a pull cord close to the shutter under controlled descent and a hand chain to open again. Every fire shutter is individually operated from a control station, incorporating open/close/stop push buttons positioned adjacent to the shutter guide.
  • A 24-volt DC auto reset solenoid is available for linking into the fire alarm or BMS.
  • Finish As standard, the curtain is self-finished light grey with the perimeter intumescent seal in black.
