Specification Summary:
Bolton Gate Company’s Fireroll range of roller shutters is the most comprehensive available in the market. A further addition is the Fireroll Acoustic E120 which combines fire resistance with a high degree of sound reduction.
During extensive testing at Salford University Department of Acoustics and two Fire Test Laboratories, the door achieved a sound reduction of a maximum 25.2dB (at 2000Hz) with a 22dB Rw coupled with a rating of E120 when tested in accordance with EN1634-1.
In keeping with the same testing, the shutter is also rated EW90 or EW120 dependent on size for face fixed arrangements.
A special double curtain arrangement is also available which reduces sound transmission further to a maximum of 39.1dB (at 2000Hz) with a 32dB Rw.
Resistance to Fire: E90 or E120 (Both internal & external)
Sound Reduction: 22db RW
Fire: Tested to EN1634-1 all in accordance with
EN13501- 2; EN13241; EN16034; EN15269

Any application where fire and sound compartmentation are required but ideally suited to:
School kitchens in multi function school halls, Exhibition Halls, Recording Studios, Warehouses, Factories.
All shutters are electrically operated by a 230-volt nominal single phase or 400-volt nominal three phase Speedsafe motor mounted on one endplate and have adjustable limit switches incorporated to stop the shutter at the end of each travel. A pull cord and hand chain are provided for use in the event of power failure.
Standard operation is via a low-level push button station with emergency stop button.
In a fire condition, gravity failsafe closing is activated by a 24-volt DC signal (0.37 amps) from the client’s fire alarm panel to the auto reset solenoid which releases the motor brake and is backed up by a fusible link.
A safety brake is supplied to comply with the safeguarding requirements of EN 12604.
Shutter curtains are constructed from 100mm high flat section continuously interlocked galvanised steel laths which are securely held in place by steel end locks. Each lath is infilled with fire resisting acoustic material.
The bottom rail comprises a standard lath fitted with a galvanised steel trim section.
Vertical guides are formed from galvanised steel double rebate channels and are supplied with suitable profiles for fixing to the structure.
The roller is constructed from seamless steel tube of adequate diameter to resist deflection and held in bearings or cups attached to the endplates.
Zinc plated mild steel of appropriate thickness relative to door size and supplied with angles for fixing to the structure.
A galvanised steel coil casing is supplied to maintain the fire seal at the head.
Fireroll Acoustic E120 is supplied with most parts galvanised as standard. Where non-galvanised parts are utilised, these are finished with one coat of primer paint.
