Economical Transparent Mylar Film Shadesare like putting sunglasses on your windows. They control solar heat, glare, fading and in winter reradiate the room's heat. They provide daytime privacy only with full vision out to the street. Rooms stay bright. They are a lamination of metalized Mylar (polyester) and dyed, UV treated Mylar joined with heat and pressure to form a flexible and durable transparent shade material.
