Product Description
Our twin skin steel shutters are the most effective way to secure an opening and/or compartmentalise against a spreading fire. Unlike single skin fire shutters, this model provides incredible radiant heat protection. To put this into perspective, normally if a fire was raging at 1200°C 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-INS4H also offers a 20dB 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.

Technical Specifications


The curtain is made from aluminium tubes and links arranged in a brick bond pattern. Our usual mesh size is 230 x 70mm. Internal horizontal rods are manufactured from 8mm diameter round bar and pinned at each end to prevent lateral movement.


The side guides are formed from 38 x 29mm extruded aluminium channels and prepared for fixing to the opening structure. 

End Plates

Manufactured from mild steel to a suitable thickness relative to door size and supplied with angles for fixing to the structure.


Generally galvanized. Any non-galvanized plates are prime painted. Customers can choose to have a powder coating of almost any colour as an additional extra.


Smaller shutters tend to be controlled by 240-volt single-phase tubular motors. Adjustable limit switches are incorporated to stop the shutter at the end of each travel. Standard controls are open/close/stop buttons for geared motors and rocket switches on single-phase motors. A safety break is incorporated in line with current Health and Safety legislation.

Galvanised steel hoods can be supplied to cover the coiled shutter and motor.
