Window films come in a wide variety of colors, shades, and performance levels. Some key considerations include whether or not you want the glass appearance to change including the level of darkness and reflectivity. The length of the warranty is another differentiator. Performance is likely the most important aspect of choosing a film. The amount of light transmission, a film’s ability to block the sun’s heat, clear of dark privacy, UV/fade protection, level of reflectivity, etc. A professional window film company can help you narrow down the options by asking you questions about your needs and desires and help you attain the perfect window performance and appearance.
