A sunshade or sunscreen for an automobile includes fold lines. The sunshade is made from front and back layers and an intermediate layer. The front and back layers each have a reflective outer surface and an insulating inner surface. The intermediate layer is made from an insulating material, such as a form. To allow for folding of the sunshade, the shade is provided with fold lines which extend between opposed edges of the sunshade. The fold lines are formed by sonic (or ultrasonic) welding.
