Acoustic Glazing
Double and Triple Glazed Windows
Intended for any internal application requiring high levels of sound transmission loss,
including double or triple glazed designs for new projects, as well as secondary elements for upgrading existing
glazing.

Construction
All units are custom designed to meet the acoustic requirements and the physical constraints presented by the
application. Units are either double or triple glazed with acoustically lined reveals. The window frame is
manufactured to fit within the builders-work opening and, where a raked central pane is employed, the frame secures
and seals the pane in place. The frames, glazing, reveals and architraves are delivered ready for site
assembly/installation. The frames are secured to suit and the architraves close minor gaps around the periphery, after
these have been acoustically sealed.
Glazing
Laminated glass is generally used, as this provides better acoustic performance than monolithic glass and is
inherently safer in the event of breakage. Most designs utilise dissimilar thickness panes of either 6.4mm, 8.8mm or
10.8mm thick glass. The panes, with the exception of centrally fitted raked elements, are pre-sealed into aluminium
frames ready for face fixing into the MDF frame. Fixings are concealed by a plastic extrusion fitted into a peripheral
recess. Care is taken with the specification of raked elements in triple glazed designs as, whilst these can reduce
resonances in the air cavity, the benefits are only achievable where the separation between panes is significant.
Toughened, Georgian Wired and Polycarbonate alternatives can be supplied if required.
Reveals
Acoustic material, usually fabric covered resin bonded glass fibre board, is used to line the reveals to provide sound
absorption between the panes.
Acoustic Performance
Windows are generally designed to meet specific performance criteria up to a maximum of Rw50-55.
