Sound Proofing with glass

[Brinda]

Hello All,
I am in the midst of renovating my house. We have a partition wall on the first floor of our house which demarcates areas for tenants and for us. This wall is only partially built and the remaining portion is intended for fixing glass. However we noticed a problem that there is no privacy due to no sound proofing. Any suggestions, and recommendations as to people in who can do a quaity job with sound proofing. Thank you.

Sound proofing can be done via many mechanisms.. if glass space is the only way you beleive that sound can come thru, you can do few things

Get a aluminium frame done with right type of felt and "kerala rubber"..they do offer quite a bit of sound proofing..added to that, go for heavy glass, such as 10mm..if it permits..pack any empty space with silicon.. any aluminium fabricators will be able to do it..

Pls remember this is not going to be studio quality sound proofing but about 80% of will be attenuated

For soundproofing you can go for saint gobain double layer glass in UPVC frame. It provides both thermal and sound insulation.
Most UPVC brands have option of sound insulation glass.

Oh thank you for this. Any UPVC brands you would recommend which are also economical and not too much on the expensive side ?

LG Hausys And Rehau are good

But doubt they take smaller orders

When I contacted Windowfab, they told me LG stopped shipment to India from December 2020.

How about fenesta? I am not a fan of upvc, i prefer aluminium

Isn't aluminium a choice? You should look at the demo in ambica aluminium on mysore road. .much cheaper, stronger..

Prominence - Madhu Industries
You can contact their sales representative Ranganath +919739289989
Specify you need sound insulation and ask for double and triple layer glass. Layered Glass will be expensive but still cheaper than other options.

Fennista is seriously overpriced and I didn't find their dealers fair. It was suggested by my architect and I suspect they should be offering a good cut to architects.
Just to give you an idea for my whole house these are quotes I received.

Fennista in their experience centre they never give any kind of per square feet rate even of you ask most basic 6'x4' 60mm slider and insist that they should visit cite. Initially their person never showed up and finally when one day my arch called and I told him that I have got quotes from 2 others and decided against fennista they started following me up.

Inital quote 18L( over the phone) for whole house later when I refused to talk to them reduced to 13L + 48K for installation (in email) so this much of margin and discount makes me weary.

Aparna Venister Initial quote 13L I didn't reply to them as I had third lower quote they reduced by themselves to 7.5 L. Actually it was their sales strategy mistake they first want to give same quote as Fennista and then show discounts. However this is something which made me decide not to go with them.

Madhu Industries (Prominence) both Initial and final quotes 7.5L fixed and they said they won't negotiate and were quite transparent showed me all the glass options including heat rejection, sound insulation colour etc and were transparent in giving per square feet rate.
so I liked them.

All quotes for white profile. It's not possible to give break up in this post as there are too many things

Aparna and Prominence are made in India.

There are cheaper chinese UPVC but the issue is they become yellowish. UPVC has titanium dioxide which gives white colour , stability and gives resistance against UV rays and prevents frame becoming brittle. Cheap chinese ones cut on titanium dioxide so turn yellow and brittle.

About aluminium frames they rattle a lot some people cite Hindalco or domal from jindal but these companies only give sections and riveting cutting is done by fabricators and there lies the problem. The tolerance values are very high and the windows rattle with wind load.

Visualizer,

Just asking, what was the requirement( approx). Even our architect has asked us to explore upvc windows. Would like to know more on it.
