After doing quite a bit of online research, I have found soundguardwindows.com to be one of the leading soundproof window vendors/distributors.
This window will be expensive. I just want to be sure I make the correct decision. I'd hate to have this product installed and payed for when I should have gone to company xyz instead. Would you be as so kind as to list some of the possible vendors I could reference towards making this final decision? I'd like to do my homework before making a final decision.
Thank you for your help.
