Sound Barrier Double Window is a double glazing system using award winning Australian designs in aluminium (Australian Design Award 1987).
This system is suitable for use when high noise reduction is required or when existing windows and doors are in need of replacement.
The double system works in much the same way as the add on system, with the added benefit of an acoustically rated primary (outside) window and acoustic sealing of the entire unit to the building during installation.
Depending on chosen configuration and glazing STC 40-50+ is provided.
