Hi Sarah,

My apology, do PM me again.

BTW, does this proofing really minimize sound? Another contractor replied my enquiry, with quote of more than $2K and advised me to install not sliding panels but the swing-type window. How was yours done?

TIA again.

Hi Reiki,

PMed!

I did swing type windows as it's more effective in sound proofing than sliding windows. The sound proofing is not 100% but good enough to cut down traffic noise when the vehicles are cruising pass, and it will be cheaper to run air con as the heat transfer is less compared to single glazed window . One of my guests who slept in the bedroom facing side road said the double glazed windows help a lot.

I noticed that my friend's double glazed windows at his condo has wider gap in between the glass panels for vaccum/gas to buffer the sound, read that it will be more effective with wider gap but HDB has a restriction on the gap
