This technological breakthrough was\u00a0originally developed by <a href=\"http:\/\/www.precisefilm.com\/madico_v-kool.html#vkool\">V-Kool<\/a>\u00a0 in 1991, and still manufactures the highest performing spectrally-selective film in the world.<\/p>\n<p>3M had the goal of making spectrally-selective films cheaper, and in some ways, succeeded. There are a couple of caveats: First, the optical clarity, or\u00a0distortion impediment of Prestige 70 is <strong>moderate <\/strong>and adds a waviness to the glass<strong>. <\/strong>Some would argue that a film that costs $8-$12\/sqft shouldn&#8217;t distort the view at all. As for Prestige 70 heat rejection, it is not constant, and on a double-pane installation will only perform between 44%-50% heat rejection, depending on the angle of the sun. Still, for those who want to save a couple bucks per foot, this is a way to go.<\/p>\n<p>Panorama HiLite 70&#8217;s distortion impediement is <strong>undetectable<\/strong>, and its heat reduction performance on double-pane glass is 51%, but its quality that comes at a higher price than Prestige 70 ($10-14\/sqft).<\/p>\n<p><a href=\"http:\/\/www.precisefilm.com\/madico_v-kool.html#vkool\">V-Kool 70<\/a> ($10-$14\/sqft) distortion impediment is <strong>undetectable<\/strong>, and offers the highest heat rejection in its class on double-pane glass (56.2%).\u00a0\u00a0<\/p>\n<p>The manufacturer names and product ID\u2019s are as follows (In order of performance<br \/>\nfrom best to worst):<\/p>\n<p><a href=\"http:\/\/www.precisefilm.com\/madico_v-kool.html#vkool\">V-Kool<\/a>: VK70 | 56.2% TSER | 64.4% VLT<\/p>\n<p>Panorama: HiLite 70 | 51% TSER | 64% VLT<\/p>\n<p>Vista: VS70 | 48% TSER | 61% VLT<\/p>\n<p>3M: Prestige 70 | 44% TSER | 61% VLT<\/p>\n<p>(TSER: Total Solar Energy Rejected)<\/p>\n<p>(VLT: Visible Light Transmission)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>With the hit the economy has taken, the use of\u00a0 &#8220;spectrally-selective&#8221; films has seen a dramatic fall.
