This reflective insulation was for a glass door to block out sun and heat in summer and keep heat in in winter. Instead of it being rolled, it was folded in thirds, then folded multiple times to get it to fit in the small shipping box. The folds and creases are not going to relax out of it. It should have been rolled smoothly the width of the panel and shipped in a longer, narrower box. If someone can tell me how to get it to smooth out, I'd give it a try, but the way it is, I don't see that just hanging it is going to relax the creases. It's a mess.
