I've seen these more and more. Airlines install them to preserve the windows and save time on deep cleaning. They are basically a dust cover for the windows.
The outer window gets very cold to the touch. The inner window is part of a thermal barrier system. The air gap between the outer window (which is thick) and the inner window is heated to help regulate the cabin temperature.
