window refurbishment/acoustic rated

hi guys
a bit of advice is needed have a window that fronts onto street and nearby train line that i would like to remove and have double or triple glazed, then reinstalled to a acoustic spec as train line in nearby,

question is
anybody know of a company that do this?
am i better of to get a new window made to size?
are there specialty companies doing acoustic windows?
house is nearly 100 years old so may not be standard size
(pretty sure that its called a double hung window ie; slide up & down vertically )
would like to keep to the heritage look of the house.

cant seem to find any info on net, would appreciate any help
thanks in advance

cheers

Went through the same exercise a while back. Standard dbl glazed windows with 12mm air gap reduce noise by approx 39%. To acheive a real noise reduction you need a large air gap , too large for opening windows. If you use 6.38mm laminated glass it reduces noise levels by approx 37% and is a lot cheaper tha dbl glazing.

Hi,

I just had our bedroom window replaced with double glazed window, 6mm glass-14mm gap (filled with a high density gas)-4mm glass and a uPVC frame. Works pretty well, but I'm noticing noise coming in through the walls and ceiling now (we live near a freeway).

The window was made to measure, approx 2700x1600, cost $2600 installed (the guys did a really good job on the install too).

The glazing came with a 10 year guarantee, and the frame 35 year. Certainteed was the company, they're in cheltenham (vic).
