      You’ll get ice on the sides, these can’t be sufficiently hermetic.

      EDIT: With some -30 Celsius outside (EDIT:happened only once or twice in my lifetime, 20 would be something more real) and +15 inside, for example, and usual humidity for a living place, where people cook etc.

        only time I’ve ever had ice build up on the inside of a window was when the window was end of life and the AC broke and it was -35 F

          What was the temperature inside (don’t think anybody remembers or even measures humidity)?

          It seems common sense to me that on the sides of a sliding window there’ll be very thin gaps, while with a “normal” window there is pressure between parts at all sides.

          But I can’t say I’ve seen many sliding windows in my life.

            like 65 F, probably around 35% humidity

            there’s a seal around the windows that slides up and down when you open it

              OK, maybe I’m wrong. I’m not very good at physics and easily believe what other people say, but since this thing is really uncommon here - I shouldn’t.
