If the upcharge for dual pane windows is worth keeping out the noise, then do it.
Yes, they help with condensation, but add no thermal value. They are NOT THERMOPANE windows like your home, they are dual pane glass.
If you are going to live in it year round, and are staying in the colder climates during winter, it may be worth the price. Otherwise, you will never know the difference, and paid for the option.
Well of course they add thermal value! Storm windows were not sealed to the original window. Nor is the plastic window seals some folks use over there stock windows in the winter. It all adds thermal value. Sealing is just a more efficient way, but typically is a waste through an an aluminum frame anyway.
