I needed to block the light from several windows in the room being used as a home theater with a projector. The easily workable material was quickly installed and completely blocked the light such that the room is completely dark when needed, at any time of the day. The material will be frequently taken down and put back up and I am anticipating that this tough, but soft and flexible, material will last for years. I can highly recommend this product
