Acoustic rated insulated roller shutter.
The Sonaroll is suitable for any application where an acoustic rating is a requirement.
It has been installed in TV studios, recording studios, theatres and exhibition halls but also more industrial applications such as turbine halls, boiler rooms, loading bays and warehouses and then also schools, serveries and reception areas.
The Sonaroll is Bolton Gate Company’s purpose built acoustically rated rolling shutter.
This sound reducing door system combines several features and benefits into one design. In addition to acting as a secure and weather resistant closure, the shutter offers significant acoustic and also thermal insulation properties.
Extensively tested at the Department of Acoustics at Salford University, the door achieved a maximum sound reduction of 27.2 dB (at 5000 Hz) with a 22 dB RW. A special double curtain arrangement is also available. This provides significantly increased acoustic performance with a maximum of 39.8 dB (at 2000 Hz) and 33 dB RW rating.
Operation
Curtain
The shutter curtain is constructed from acoustically rated 100 mm high foam bonded continuously interlocked galvanized steel laths with a flat profile. The laths are securely held in place using black nylon end locks.
Bottom rail
The bottom rail comprises a standard lath fitted with a black trim section carrier and rubber weather seal.
Side guides
Vertical guides are formed from rolled galvanized steel in a double rebate profile with twin brush strips. Full height angles are provided for mounting to the structure.
Roller
The roller is constructed from seamless steel tube of adequate diameter to resist deflection and held in bearings or cups attached to the endplates.
Endplates
Zinc plated mild steel of appropriate thickness relative to door size and supplied with angles for fixing to the structure.
Casings
A galvanized steel coil casing and motor casing are provided as standard to close off the operating mechanism and complete the aesthetic appearance of the door. A full span acoustic infill is also mounted directly below the coil casing (provides an additional 1 dB under test conditions).
Finish
Galvanized steel is the default finish but please refer to Options below for alternatives.
