Best Double Glazing for Noise

schmoo

I have recently replaced wooden double glazing with upvc double glazing with 28 mm units that have argon gas, with toughened glass front and back. I don't know what the thickness of the panes front and back are, but I am guessing they are both 6mm

We live beside a busy road with a bus stop, and I have noticed no improvement in the noise situation, which was one of the main reasons for replacing the windows.

Any ideas about what can be done without actually replacing the windows altogether?

Two other companies have told me that if we replace the units , with the new units having a front pane that is thicker than the back pane (ideally 8mm front & 6mm back), and that if the inside of the front pane is laminated, that this should significantly improve the situation. Neither of them are recommending triple glazing

Any ideas on whether I am being given good or bad advice?

Having just spend 10K I don't want to screw up again, and traffic noise is very intrusive still

What ventilation have u got in the rooms in question: wall vents/window vents?
Do the window seals work well?

What material was used to make the frames in the opes airtight? Xpanded foam perhaps:

Do u live in a 2 story or bungalow?

In relation to the triple glaze, I stayed in a hotel in Germany where, on the 4th floor I was at eye level with a bend on the autobahn which was on an elevated road about 30 meters away from the window.

The windows were quad-glazed, with quad rubber seals and there was no sound when closed.
Once I opened the seals the noise started.

Sound need air to carry it, hence look very closely at the possible air paths.

While I've done a bit of work with acoustics it's been more on noise/vibration transmission than windows - but the general principle is heavy mass stops noise. Have a look at the products below - in general the STC improves as the thicker glass is used.

I wouldn't take the advice of a general windows/doors crowd - as it seems to me that you are particularly sensitive to the noise - go contact a specialist, and get the right thing for the job. BTW I'm not endorsing the company above, never used them, just the first crowd to show up on google!

I am looking into sound proofing one room for a music studio. You can buy windows that are angled differently to reflect the sound waves.

The double glazed windows are fitted something like this \ / instead of like this I I.
