UV light also contributes to heat gain, but because most window films reduce 99% of the UV, we&#8217;re not including this factor as a variable.<\/p>\n<p>The more visible and infrared light you reject, the more energy you save. The maximum available performance for architectural window films\u00a0is around 80% heat reduction. These high-performance films\u00a0have a reflective exterior appearance and are usually only applied to commercial windows and skylights.<\/p>\n<p>Most\u00a0residential window films\u00a0reduce around 55% of solar heat from entering the home. These products are designed to have a subtle appearance (lighter in color and less reflective than high-performance films) and sacrifice performance for aesthetics.<\/p>\n<p><a href=\"http:\/\/www.precisefilm.com\/madico_v-kool.html#vkool\">Spectrally-selective films<\/a> can reduce the same\u00a0level of heat as traditional home window films <em>without<\/em> being reflective <strong>or<\/strong> dark. These films reject a high level of infrared light, so homes in colder climates will\u00a0get the added benefit of\u00a0increased heat retention in the winter months. The combined energy savings throughout the year\u00a0comes to\u00a0around 35%-50%.<\/p>\n<p>There is no way to accurately calculate how much energy window film will save you in your specific application. The compass orientation of the glass, the number of windows, size of the windows\u00a0and\u00a0type of glass you have\u00a0are all factors that affect your bottom line energy savings.<\/p>\n<p>If your windows face north and you get little or no direct sunlight through them, window film will do little to help save energy. Heat issues in these situations are more often caused by poor circulation and\/or the room being located on the top floor of a multi-level home.<\/p>\n<p>If you have windows that face south and get direct sunlight for most of the day, you will quickly notice a significant difference in energy expenditure. Similarly,\u00a0a\u00a0&#8220;wall&#8221; of windows that face east and\/or west will also\u00a0exhibit a\u00a0high\u00a0energy savings after the application of film.<\/p>\n<p>As a general rule,\u00a0energy saving window film will pay for itself in energy savings between 2 and 5 years after you have it installed.
