SNRLL

The SNRLL roller shutter combines several features/ benefits into one high quality attractive design. As well as providing a secure and weatherproof closure, the SNRLL offers a high degree of thermal and acoustic insulation. Having been tested at the Department of Acoustics at Salford University, the door achieved a sound reduction of 27 dB Rw. As such, they are ideally suited to external openings where the acoustic envelope must be maintained such as power stations but are equally at home in internal applications where they act as a sound-break between two rooms, e.g. exhibition halls. They are available in large sizes (up to 10 m high) and are available in a 21 dB fire rated version.
