<p>A multi-layer flexible sheet is provided for hanging freely on the interior room side of a window, or the like, that reflects radiant heat from inside the room back into the room with high effective reflectivity, transmits light from the window into the room adequately for looking out, is easily rolled up when not needed, and, furthermore, can be used in summer to reflect out undesired heat and glare from incident sunlight without undue loss of transparency for looking out. A synthetic resin layer of polyethylene or polypropylene having a thickness not exceeding 0.1 mm is on the room side of the laminate and has a metallic film on its outward-facing surface of gold or aluminum that does not need to be of high uniformity in thickness. A cover layer of transparent synthetic resin on the side facing the window protects the metallic film from mechanical damage and is of strength and thickness sufficient to supply any additional necessary mechanical stability.</p> |
