About two years, I had new Milgard vinyl windows (double-pane, filled with argon gas) installed in my home, and was surprised and pleased by how much they reduced noise from outside. There are many other manufacturers around the country, and I'm sure that if you call a local glass supply company they can recommend someone to you.

the new impact resistant glass now used in florida(glass/laminate/glass sandwich) is even more soundproof than insulated glass. here in florida you can get them at home depot and all window sales outfits. your local suppliers can surely special order for you.
