Fire Shutter - Fireroll Acoustic - Acoustic Rated and Fire Resisting Roller Shutter

Bolton Gate Company’s Fireroll range of roller shutters is the most comprehensive available in the market. A further addition is the Fireroll Acoustic 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.
