A double door like that is going to be annoying to use and I would only install one in a very low traffic area.

Going to a garage, you already have one air lock, the garage door, so the seal of the entrance door you install is going to get very little stress.

Having two doors like this is also going to cause you to leave both of them open longer, letting more heat out, as you fumble with both doors, so if you end up using this doorway very much it might end up being a larger heat loss then planned.
