If you’d like to increase your home’s beauty and privacy, as well as improve energy efficiency, take a tip from the automotive world: Tint the windows.
Residential window film is a plastic film made from PET, the same plastic used in water bottles. Some films are clear, and are made of multiple layers of plastic to prevent shattering (similar to the coating on a car windshield). Others are tinted with dyes, pigments or metals to reduce the light coming through the window and block harmful UV rays.
They are typically applied on the inside of the window, and are scratchproof to make the coating more durable. Window film comes in a variety of thicknesses, depending on the job it’s doing.
