Window manufacturer Mumford & Wood Ltd has supplied replacement windows in the massive renovation of the Grade II-listed Jessops Hospital, now the music school of the University of Sheffield.
Mumford & Wood designed and supplied around 250 bespoke, double-glazed, acoustic Conservation box sash windows, each with a fanlight.
For areas overlooking pedestrian street traffic ‘double-double-glazed windows’ – a double-glazed unit in the external opening using acoustic glass and another double-glazed unit in the internal opening separated by a 75mm cavity – were used.
“Effectively we used a double-glazed Conservation box sash window either side of a void in the same opening which doubly contributed to the acoustic control of this fantastic music school,” said managing director Dave Snowling. “In most cases we work toward reducing unwanted noise from entering a building; in this case we needed to trap the sound of music within the building and avoid it from escaping!”
The Conservation range is made from clear grade larch, only from sustainable sources. The windows are BFRC rated A-C, depending on size and specification, and carry Kitemark, Energy Trust and Secured by Design accreditations.
