I didn't realize that some windows were made for storms and other were
not. That's not addressed in the literature I've read, but I have
taken your suggestion and emailed the manufacturer. I may need to
send them a photograph before they know what I'm talking about.

Most modern windows will not be designed with storms in mind. Some of
these are made for the southern market. Tennessee is pretty far south
but for sure gets some cold weather. In other cases, double or
triple paned windows are already so efficient that no storms are
needed.

In some cases a storm window can be fitted into the location where
your window screens reside. Typically sreens are swapped for storms
seasonally. You local hardware (Ace) may be able to build this type
of window for you with the same thickness frame as your existing
screens.

I live in Minnesota where a lot of older homes have the storm
windows. Storm widows here are only used on the old-fashioned windows
that were designed with them. Folk with modern windows have no need
for storm windows and do not use them. Your best choice for noise
reduction will be new windows.
