Window tinting is the application of a thin film to the windows of a car, usually made of polyester or dyed film, to reduce the amount of light and heat that enters the vehicle. It can be used to improve privacy, reduce glare, and protect the interior from fading. Window tinting can also help to improve fuel efficiency by reducing the amount of heat that enters the car, which can reduce the load on the air conditioning system.
Window tinting has been around for decades, but it has become increasingly popular in recent years as the technology has improved and the cost has come down. Today, there are a wide variety of window tinting options available, from simple clear films to more complex films that offer a variety of features, such as UV protection, heat rejection, and glare reduction.
