But only some of them actually stop the heat that overworks your car&#8217;s AC. With more than 39 years of experience in the automotive industry, we believe that when we say UV vs IR blocking on car glass sounds like one feature, but they both have two different agendas. And your car&#8217;s marketing brochure is banking on you never asking which one does what.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Step into a Maruti Suzuki showroom, ask about the Baleno&#8217;s Zeta or Alpha trim. The pitch says UV-cut glass that blocks harmful rays. And eases your AC compressor&#8217;s workload. But Uv is a different player, wrecking your skin and interiors. In contrast, infrared radiation causes heat. Block one, and the other struts in like nothing happened. That&#8217;s exactly where windshield protection film, window tinting, and window film earn their keep. In this blog, we decode both.<\/span><\/p>\n<p>&nbsp;<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_76 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div

It has a <\/span><span style=\"font-weight: 400;\">wavelength range of 100-400 nm. It sits between visible light and X-rays on the electromagnetic spectrum. It is important for vitamin D production; meanwhile, it can also cause sunburn, premature aging and skin cancer.<\/span><span style=\"font-weight: 400;\"> In an automobile, UV rays can fade the color, interior and upholstery. The leather and plastic in the interior can start cracking due to prolonged UV exposure.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_is_Infrared_IR_Radiation\"><\/span><b>What is Infrared (IR) Radiation?<\/b><span style=\"font-weight: 400;\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">IR is part of the electromagnetic spectrum. It is electromagnetic radiation just beyond visible red light. The wavelengths are shorter than microwaves but longer than visible light. It makes up around half of the sun&#8217;s total energy. When you stand in sunlight and feel warmth, part of that sensation comes from infrared radiation.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">When sunlight hits your car\u2019s glass, the visible light and UV rays penetrate the glass. Your dashboard, carpet and seats absorb that heat. MGA Research, in its article Why Sunlight is the Most Destructive in Automotive Materials, states that auto glass acts as a one-way trap. It re-radiates that energy, creating a powerful greenhouse effect. On a summer day, your cabin\u2019s heat can reach up to 60\u00b0C due to IR rays. With this heat load, your AC has to work extra to cool the car down. This leads to increased fuel consumption in gas cars. EV cars experience reduced driving range.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_is_Visible_Light_VLT\"><\/span><b>What is Visible Light (VLT)?<\/b><span style=\"font-weight: 400;\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Visible light is the electromagnetic radiation a human eye can see. It occupies a tiny fraction of the electromagnetic spectrum. Think of it as a sandwich spread between IR and UV rays. Visible light makes up roughly 44% of the sun\u2019s solar energy reaching Earth. Visible light acts as a secondary catalyst for solar damage. Lowering VLT can decrease the cabin heat but reducing it too much can impact driving as visibility reduces too.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h4><span class=\"ez-toc-section\" id=\"How_IR_UV_and_VLT_Together_Increase_the_Heat\"><\/span><b>How IR, UV and VLT Together Increase the Heat?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">At sunlight level, the common breakdown is:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">53% IR<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">43% visible light<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">4% UV\u00a0<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Does_UV_Blocking_Make_Your_Car_Cooler\"><\/span><b>Does UV Blocking Make Your Car Cooler<\/b><span style=\"font-weight: 400;\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">Indirectly. UV blocking can protect the interiors from fading. But it is not the main reason a car feels cooler. It helps cut down harmful sun exposure. It can reduce the heat slightly because it only makes up around 4% of the sun\u2019s energy. The real player is IR rejection.<\/span><\/p>\n<p>&nbsp;<\/p>\n<table>\n<tbody>\n<tr>\n<td>\n<h4><span class=\"ez-toc-section\" id=\"Myth_vs_Fact\"><\/span><b>Myth vs Fact<\/b><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<h5><span class=\"ez-toc-section\" id=\"A_film_with_99_UV_rejection_can_reduce_cabin_heat_noticeably\"><\/span><b>A film with 99% UV rejection can reduce cabin heat noticeably?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h5>\n<p><span style=\"font-weight: 400;\">No. It\u2019s a myth. 99% UV rejection does not mean significant heat control.

It reduces fading and cracking of dashboards, seats, and trims.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Why_IR_Blocking_Has_a_Bigger_Impact_on_Car_AC\"><\/span><b>Why IR Blocking Has a Bigger Impact on Car AC<\/b><span style=\"font-weight: 400;\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">IR blocking has a bigger impact on car AC and heat reduction because it carries most of the heat to the cabin. When less IR enters the cabin, the interiors are less warm. The AC achieves the target temperature quickly. This improves the overall comfort and reduces AC runtime. Window tinting solutions infuse technology to provide maximum IR rejection that increases fuel efficiency and reduces battery consumption.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_Is_TSER_The_Actual_Heat_Rejection_in_Window_Films\"><\/span><b>What Is TSER: The Actual Heat Rejection in Window Films<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">TSER stands for Total Solar Energy Rejection. It is the most accurate metric to measure how much heat a windshield protection film, window film or window tinting can block. Other numbers look at the fraction of the sun\u2019s energy. Whereas TSER measures the percentage of all solar energy rejected across the solar spectrum. It combines IR, UV and VLT. A higher TSER means better heat rejection in aftermarket window films. So always look at the TSER percentage to know the actual cooling performance of your window tinting and windshield protection film.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_Is_a_Good_TSER_Rating\"><\/span><b>What Is a Good TSER Rating?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<table>\n<tbody>\n<tr>\n<td><b>TSER Rating<\/b><\/td>\n<td><b>Performance<\/b><\/td>\n<\/tr>\n<tr>\n<td><b>60%-70%<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Excellent<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>50%-59%<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Good<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>35%-49%<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Average<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Below 35%<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Poor<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Window_Films_Reduce_Cabin_Temperature\"><\/span><b>How Window Films Reduce Cabin Temperature<\/b><span style=\"font-weight: 400;\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Window films reduce cabin temperature by limiting the solar energy that enters the cabin through the glass and windshield.
