Quiet windows (soundproofing)

[markocosic]

Hello,


3rd floor apartment; city; traffic noise. Walls are brick, solid, and ~600 mm thick - the noise is coming from the windows only, which want replacing.


Any pointers?


This site appears to suggest:

-large air gap
-dissimilar glass thickness to offset resonant frequencies
-laminated glass to damp vibrations/offset resonant frequencies
-triple glaze with a large gap to the internal glazing

Who sells the stuff? Any experience?


Thanks,
