Acoustic Roller Shutter - Sonaroll - Acoustic Rated Insulated Roller Shutter

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 high quality attractive 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 27.2dB (at 5000Hz) with a 22dB RW, which is considerably higher than other similar roller shutters on the market. A special double curtain arrangement is also available. This provides significantly increased acoustic performance with a maximum of 39.8dB (at 2000Hz) and 33dB RW rating.
