Reflective window film has become popular among homeowners who are energy conscious. Its low price and ease of application also makes it a popular purchase. There are different types of window film designed for different use, including light blocking, privacy, insulation and reflective. These are all available in colors, white and mirrored. None of these raises the temperature of the glass—in fact, some will actually lower the temperature in the summer. You may not a slight temperature increase when using the various depths of black film, so if you are concerned about this, check with the manufacturer or installer before you purchase that type.
