Certain example embodiments of this invention relate to refrigerator/freezer doors that include three substantially parallel, spaced apart glass substrates that effectively form two insulating glass units (IGUs), and/or methods of making the same. The substrates in the two IGUs have one or more surfaces coated with a low emissivity coating and also have one or more other surfaces coated with an antireflective coating. In certain example embodiments, one or more of the substrates may be low-iron substrates. For instance, certain example embodiments may include a center substrate that has an antireflective coating disposed on both major surfaces, whereas the outer substrates have low-E coatings disposed on inner surfaces thereof. Advantageously, certain example embodiments combine high energy efficiency with high light transmission.
