Best type of sound proof windows for my bedroom?
« on: October 16, 2015, 11:51:29 AM »

Hi guys. All our bedroom windows face the road and to add to the problem, my house is on the 1st floor. The primary noise problem is the traffic noise especially the honking noise (I am from Mumbai, India where people have a disease of unnecessarily honking :P). Also there is a construction site nearby whose work starts at 8 am in the morning itself. The existing windows are normal builder fitted single glazed aluminium sliding windows that hardly help in reducing the noise.

Now I have a few queries. Firstly, I am confused whether to replace my existing windows or add an additional window inside by keeping the existing one. From what I understand, installing an additional interior window behind the existing window is the best solution. My window sill width is just 7.5 cm. The total window frame area is 40.53 sq. ft. There are 4 tracks. 3 sliding windows and 1 mosquito net frame. Will an additional window fit within that sill width? If required, I can do away with the mosquito net to increase the width of the sill.

However, if the additional window is not possible and I have to replace the existing windows only then which option is better, a double glazed window with different glass thickness and an air gap in between or a laminated window? I have been getting contrasting opinions about this, some say double glazed is better and some say laminated is better. One of the contractors has given me options for both double glazed and laminated glass in UPVC frame. The configuration for double glazed is 6mm clear glass + 10 mm spacer + 5mm clear glass. The configuration for laminated glass is 12 mm clear glass + .75 EVA laminate + 5 mm clear glass.

Lastly, the unending confusion of aluminium vs UPVC window frames. Now some say that aluminium is better because it has more mass. However, I have also read that UPVC is better since there are less number of gaps in UPVC as compared to aluminium. And if the UPVC is metal reinforced, then wouldn’t its mass be the same as aluminium then?

Kindly suggest the best possible and economically feasible solution for my problem.

Guys, kindly reply on my other post since I had forgotten to add a detail in this one and there is no way to edit or delete this post now.

Ok I accidentally deleted the other post by mistake.
But to easily answer your question
You are basically trying to create the greatest air space between two panes of glass.(or 2 windows)
The heavier the glass and the greater the air space = the greater the reduction.

We would recommend at least 2" air space or greater.

UPVC frames are better then aluminum.

Hi Randy. Thanks for the reply. Well I doubt if any of the window profiles here will have a dead airspace of 2 inches between 2 panes. The other method would be to have a secondary window which honestly I am not very keen for.

The two options I have mentioned above (configuration for double glazed is 6mm clear float glass + 10 mm spacer + 5mm clear float glass OR The configuration for single glazed laminated glass is 12 mm clear glass + .75 EVA laminate + 5 mm clear glass) won't give any noticeable sound reduction?
This website (http://www.build.com.au/window-acoustics-and-noise-control) suggests that single glazed laminate is better than double glazed clear glass at reducing traffic noise. Is it so?

Otherwise what would be your recommended glass configuration?

That is a good article, as you read a secondary window would be the best option.

If that is not possible it does fall back to mass law.

So yes thicker laminated glass with dissimilar thicknesses would work as well...

For us it always comes back to cost vs. reduction so we tend to lean for the best.
