Sonaroll acoustic roller shutters act as a secure, weatherproof closure with high thermal and acoustic insulation values with sound reduction up to 27 dB Rw.
The shutter curtains are made from 100mm continuously interlocked galvanised steel laths that are held in place by end locks. Each lath is infilled with acoustic material and has a bottom rail with a rubber seal.
It has vertical rolled steel guides in a double rebate that are fitted with twin, full-height brush seals and supplied with suitable angles for fixing to the structure.
Operated by a 400 volt, 3-phase geared motor mounted on one of the endplates.
Adjustable limit switches are incorporated to stop the shutter at the end of each travel and a safety brake is incorporated in line with current Health and Safety legislation.
