I use THIS STUFF between the blinds and windows. When not in use I (summer heat and winter cold) they are under the mattress, rolled up and in a shirt closet or behind the couch. Plus being flexible and about 1/4" thick installing is simple the them blind strings hold them in place.
That insulation is great for windshields. It bends to the contour and keeps out most of the heat in the Summer and most of the cold in the Winter. As mentioned, when you are done with it you just roll it up and store it in the basement or any other convenient location.
