Louvre windows have never been synonymous with sound insulation. But now, a new breed of louvre windows have achieved more impressive sound insulation properties then ever. So much so that they have been specified by architects and installed in high noise buildings such as the Virgin Lounge at Gold Coast International Airport and the Offices of the Brisbane Airtrain Terminal.
In tests carried out at the National Acoustic Laboratories, in accordance with Australian Standard AS 1191-2002, these impressive louvre windows achieved a weighted sound reduction index of Rw (C;Ctr) = 32dB (0;-1).
This 32dB reduction was achieved with the Safetyline Jalousie louvre window frame and a 6.38mm laminate glass. However, when used with Viridian VLam Hush laminate glass (specifically developed with an interlayer to dampen noise and provide enhanced sound insulation performance) noise reduction could be reduced a further 9.5%, improving the reduction of sound to 35dB. For more information on the test results see links at bottom of this email.
What sets Safetyline Jalousie apart from other windows is the use of marine grade seals help achieve greater sound insulation, along with the selection of the most appropriate grade of glass for each project.
Most architects are surprised when they are presented with these sound insulation test results and increasingly Safetyline Jalousie Louvre Windows are being specified in projects that traditionally would not have been considered appropriate.
If you are considering options for sound insulation in future projects, keep Safetyline Jalousie Louvre Windows in mind.
