I am new here and I am having a little a bit of trouble choosing right product for soundproofing existing windows. We have purchased Unit which is on very busy rd. I think the only thing which would comply with strata is to install secondary windows I have found couple companies. http://www.soundbarrier.com.au http://www.soundblock.com.au Being Sunday I can not get any quotes today. Does anyone have experience with similar issue or with this companies? I m also having hard time finding price (approx). Any help would be great. Re: Sound Proofing Windows 2Oct 12, 2008 9:04 pm Normal window companies should be able to provide you with a solution for sound deadening. I can tell you that it's going to be an expensive exercise!
There are a few ways to keep noise down with glass i.e - Thicker glass - Laminated Glass - Double Glazing If you give the glass companies the measurements of your windows and specify the type, they shuld be able to give you a price over the phone.

The products you've found already are probably the most efficient & economical choices. Also have a look at http://www.magnetite.com.au/ Double glazing is rediculously expensive and only starts to become effective as a sound barrier when the gap gets out past 100mm.

Also have a look at http://www.magnetite.com.au/ Double glazing is rediculously expensive and only starts to become effective as a sound barrier when the gap gets out past 100mm. Magnetite quoted me $300/m2 at the Home Show... and that is rather expensive for secondary glazing... Also double glazing is an effective sound barrier even at 12mm - EcoClassic is STC 34.5 - glass thickness is the critical factor "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy.

It is a 6.5mm lamintated saftey glass, which can be glazed into most existing aluminium or timber frames. It isn't cheap, last job I did in it was charged at $185/sq m. This was for an entire house, so it will be more expensive to do one or two windows.

The important parameter to consider is the STC. Here is a outline on the subject. http://en.wikipedia.org/wiki/Sound_transmission_class A sound engineer told me that it was a bit more complicated that this but this summary should suffice. Here is commercial website indicating what is possible. http://www.vuewindows.com.au/sound-glass.aspx Re: Sound Proofing Windows 7Nov 24, 2008 4:05 pm dymonite69 Here is commercial website indicating what is possible. http://www.vuewindows.com.au/sound-glass.aspx This is good basic stuff. We tested a window with 6mm glass and with 6.38 laminated (with the PVB layer mentioned in the link) and the difference was not 1 dB. Testing is expensive and rigorous and not many people do it, prefering instead to make claims which when in situ are impossible to prove or disprove. The best results (without going to the 100mm airspace) come from differentially thick glass in a double glazed unit with a argon.

The best results (without going to the 100mm airspace) come from differentially thick glass in a double glazed unit with a argon. If you go by the Wikipedia table, for any given noise level you need at least an STC change of 5 before there is a noticeable difference and at least 10 before it is largely removed. Purely based on physics, sound attenuation can be achieved by: a) passing through several successive layers of different acoustic impedence (resulting in reflected energy) b) passing through an air gap which will dampen vibrations (and reduce resonance/ringing) c) increasing the thickness of the material d) changing the surface texture of the material (resulting in scattering) e) using a material with a higher attenuation co-efficient (probably limited for glazing applications) Re: Sound Proofing Windows 9Nov 24, 2008 8:42 pm dymonite69 EcoClassic dymonite69 Here is commercial website indicating what is possible. http://www.vuewindows.com.au/sound-glass.aspx This is good basic stuff.
