Calculating the approximate fade factor reduction of a window film is a simple process. Add the Visible Light Reduction percentage of the film to the Total Solar Energy Rejection percentage of the film, then divide by 4. Add 40% to this figure and voila, you have your estimated Solar Fade Factor Reduction Percentage.<\/p>\n
Example:<\/p>\n
A film with 60% Visible Light Reduction and 55% Total Solar Energy Rejection – (.60+.55) = 1.15, Divided by\u00a04 is\u00a0 .2875 (28.75%), add .4 (40%) to that figure and you have a total of .6875, or 68.75% – this is the total approximate solar fade factor reduction of the film in question.<\/p>\n
Clear films with no heat or visible light reduction only have the benefit of the UV blocker added to the adhesive, which qualifies for the 40% added on top of the calculated figure.<\/p>\n
This is an invaluable tool to anyone in the process of choosing a window film to protect their funishings from the damaging effects of the sun. Most people discover that the expensive Spectrally-Selective film they were so excited about really doesn’t offer as much protection as a traditional film at half the price. Others are willing to give up additional protection in favor of a higher light level. In either case, with this formula at your disposal you will be able to quantify the benefit of each film you are considering before making your purchase.<\/p>\n","protected":false},"excerpt":{"rendered":"
