First thanks for the recommendation Mcfarang , would be nice to know who you are !

As most of the longer members may be aware i'm the owner of PSD.

Only information offered on this post.

For noise reduction the use of "double glass" is of course the option.

Just a few points ,

The glass used must have different thicknesses and seperated by a spacer bar,( standard would be 5mm glass, spacer bar of 9mm and then 6mm glass giving a 20mm sealed unit ) However it also depends on the noise you can hear and want to cut out , is it tuk tuks , bass from a disco , general traffic or soi dogs ? as this would dictate the glass used ( perhaps laminated with float glass would be the ideal solution )

To use the same thickness of glass on both would actually increase the noise as it would act as a drum transferring the noise from outside in.

Inert gas ( argon for example ) is effective only for heat transfer and has no effect on noise reduction.

One major point often overlooked is the window design , a sliding window by design is only effective at noise reduction to around 70% , a casement window nearer 80% and a fixed window closer to 90%.

There are two major Thai flat glass manufactures Thai Assahi and Guardian Industries and nearly all window companies buy there glass from them ( not double glazed , this is done by the individual fabricators )

For the OP the double glass ( depending on sq.m works out at approx 1,000thb to 2,000thb per sq.m ) depending on size and then the window frame on top ( sliding , casement , fixed at different pricing )

Hope this helps

Two points: firstly, Thai Assahi will fabricate units, they did so for my condo at Floral five years ago. Secondly, the inert gas in the void is important for noise reduction. If you look at how sound travels between in the void it's key that there is nothing in the void (even air) that will allow the sound waves to reverberate, doubters on this point should check the net et al to understand the dynamics of sound travelling through air.

Thai Assahi , may fabricate the glass units but not the frame as requested by the OP and i would suggest it would be considerably more expensive to buy the frame and glazing from two different companies rather than the same one. If you obtained frames from them they sub contracted the work.

As for the inert gas , jury out on that one on . The effect between having and not would be hard , if at all possible for anyone to distinguish between. More important is the glazing option ( 5, 6 , 6.4 , 8 , ) laminated or not.

Assahi supplied the units which a third party then installed in existing aluminum frames that were designed for single pane glass but could be successfully channeled to accommodate double pane units.

Inert gas: the jury is in and has been since modern science began - if there are no molecules in the void there is nothing for the sound waves to reverberate on, please google, Totally agreed that two different thicknesses of glass.are required within the same unit.

Hi, I have to agree with Chiang Mai regarding the inert gas. Aisglass website is a site by Asahi Glass India. Fantastic and easy to understand resource for glass products. A couple of key points that I have learnt and picked up:

a) IGU (insulated glass units) are excellent for thermal insulation. But IGUs do not provide good acoustic insulation. For double glass units to have any benefit from an acoustic perspective, the gap should be a minimum of 50mm, recommended at 100mm. For good acoustic insulation, one should perhaps look at using an acoustic laminate glass, which should improve OITC rating by as much as 3 - 5 db.

B) {what the glass companies dont tell you} - IGU units are perfect for cold climates as they act as a barrier in preventing heat from escaping through conductive (non-solar) heat transfer [eg. heat from your heater escaping through the glass]. But in hot, tropical climates, your primary mode of heat transfer comes from solar energy heat gain straight through the windows. So what happens when you have an IGU window with two panes of normal clear glass is that the heat will come through the IGU relatively unrestricted, but then becomes trapped inside the home as the IGU now acts as an excellent barrier against thermal transfer by conduction - the IGU glass does not allow the heat to escape back out. One way of mitigating this phenomenon from occuring is to have a combination of Low-e and tinted glass as your panes in an IGU, and that helps to minimize solar heat gain into the home. But utlimately, heat will pass anyway and if there are no vents, or if the windows are not left open for the heat to transfer back out again, you will be left with a hot box when you come home from work at night.

In my humble opinion, the most effective solution for windows in our tropical environment is to use green tinted laminated glass throughout the home, and upgrade the laminate to an acoustic laminate where the windows are next to roads with significant traffic.

If you look at how sound travels between in the void it's key that there is nothing in the void (even air) that will allow the sound waves to reverberate, doubters on this point should check the net et al to understand the dynamics of sound travelling through air.

I'm confused. If no molecules, then, it's a vacuum. Sound travels through all gases, all it does is change the frequency (like talking in high pitch after breathing helium), but, doesn't affect amplitude.

This is how I see the case as well. Inert gas basically means that the gas (mostly noble gases) are non-reactive.

--Wiki-- http://en.wikipedia.org/wiki/Inert_gas

An inert gas is a non-reactive gas used during chemical synthesis, chemical analysis, or preservation of reactive materials. Inert gases are selected for specific settings for which they are functionally inert since the cost of the gas and the cost of purifying the gas are usually a consideration. Neon and argon are the most common inert gases for use in chemistry and archival settings.

-- --

Vacuum blocks both heat conductivity and sound waves, which both require an medium to get forward. However it does not block heat radiation. Glass and lamination can help with that.

Argon is an noble and inert gas which has lower heat conductivity than air (N2, O2). Therefore it is used with the windows and for example in wet suites while diving in cold conditions.

Argon has a speed of sound 323m/s, which is similar to air 340m/s. I'm not sure if these values correlate how well the sound is passed trough the medium, but I my uneducated guess would be that there is no significant difference between those to gases.

Perhaps the following will help:

What is Argon-Filled double glazing?

The cavity between the panes of glass in conventional double glazing is filled with air, providing a substantial improvement on single glazing. The principle is that it reduces the heat transfer between panes, keeping the heat in during the winter months, and keeping the heat out during the summer.

Replacing the air with Argon, an inert gas, further reduces the heat loss, and therefore improves energy efficiency.

What are the benefits?

  • Argon is a non-toxic, colourless, odourless, chemically inert gas. It has a thermal conductivity which is just 67% of the conductivity of air.
  • The gas is six times denser than air, and this has an impact not only on thermal conductivity, but on acoustic performance as well.
  • Argon gas significantly reduces the window’s U value, saving money on heating and increasing a properties overall energy rating.
  • The higher temperature of the gas sealed in the cavity also helps to reduce the likelihood of condensation forming between the panes.
