What is the difference between a two-track and a triple-track storm window?
The number of channels, and so the number of sashes. A two-track carries one glass sash and one screen. A triple-track carries two glass sashes and one screen.
Which one covers more of the window with glass?
A triple-track. A two-track glazes roughly half the opening at a time, while a triple-track can glaze the full opening in winter and still position the screen freely in summer.
Why would I choose a two-track?
Cost per opening is lower, which matters when you are ordering for a whole house. The frame is also slimmer, and on a single-hung window where only the bottom sash operates, the second glass sash of a triple-track is not doing anything you need.
Is a two-track good enough for winter?
For most openings, yes. With the glass sash closed it creates the same insulating air gap against your primary window that any storm window relies on. The difference is how much of a tall opening the single sash can cover.
Does either one include a screen?
Yes. In both, the screen is built into the same frame as the glass, so there is no separate screen to buy, fit or store between seasons.
