    You can make insulated glass doors fairly easily. Just sandwich a gas between layers of glass. Look at any modern window for an example.

      Still not as insulating as a thick door with the manufacturer’s choice of insulation material. Double/triple pane glass is far better than a single pane window but a window is still a window
