NAME OF DEVICE USED TO MEASURE TINTED WINDOW PERCENTAGE INSTALL

When manufacturers design window film, they incorporate different materials designed to block specific energy wavelengths. Window Film Visible Light and UV Specifications The approximate distribution of energy from the sun above Earth’s atmosphere. IR energy is responsible for the transmission of heat to the Earth’s surface.

IR energy falls in the 700 nanometer to 1 µm region. On the other side of visible light is infrared energy (IR). UV light is in the 10 to 400 nanometer range. The energy from the sun at lower wavelengths than violet light is called ultraviolet (UV) light. The majority of the solar energy reaching the Earth is visible light, with particular emphasis on the blue spectrum with wavelengths just under 500 nanometers. In fact, NASA calculates that an impressive 1.365 kilowatts of energy per square meter reach our upper atmosphere. The sun emits a vast amount of energy through the visible and invisible energy spectrum. This sounds like a great place NOT to visit! This thoroughly violent state is fed by nuclear reactions, and it is estimated that you’d need to explode 100 million tons of dynamite every second to equal the energy produced by the sun. The sun has a surface temperature that is estimated to be about 10,000 degrees F and a core temperature that exceeds 27 million degrees. Before we get started, let’s take a look at the energy emitted by the sun and how it affects us. In this article, we are going to talk about window tint heat rejection and explain what the Total Solar Energy Rejected (TSER) rating and various infrared energy rejection numbers that film manufacturers publish really mean. You can with a dark dyed film to match your aesthetic (and your budget), or you can opt for a lighter shade of ceramic film while enjoying increased performance without resorting to blacked-out windows.A few weeks ago, we published an article that explained how window tint darkness specifications work. The films offered by Tekton and our experienced Autobahn dealers give customers tremendous flexibility. If you opt for a nano-ceramic window film, you have the opportunity to enjoy much greater heat rejection without having to choose an extremely dark shade of tint. In the past, if you wanted more heat rejection, you had to go darker with your window film. If you have any questions about VLT or are interested in any of our automotive products, just give us a shout – we’re always happy to chat.ĭo VLT specs and performance always line up? Understanding VLT ratings will help you ensure that you find the ideal product. VLT and film performance vary independently we have nearly invisible films that still reduce glare and block broad-spectrum UV radiation. The devices use a laser to test the light permeability of the window. There are devices used by professionals and law enforcement that measure VLT levels with extreme precision. Experienced automotive window tint technicians will be able to estimate your VLT to an accuracy of about 5% just by looking at it. There are several ways to find out the current VLT of your car’s glass.

How do I know my vehicle’s current VLT %? From this example, you can see that applying a film with a 10% VLT rating does not result in the glass with 10% VLT. For example, applying a 10% VLT film (quite dark) to a glass that has a 75% VLT (quite clear), you multiply 10% x 75% = 7.5%. To calculate the total VLT of a vehicle’s window once tint has been applied, you must multiply the VLT of the glass by the VLT of the tint that is applied to the glass. The glass that most automakers use has a VLT rating of about 80% (which is quite clear), but the default VLT of each car model varies.

The windows that car manufacturers install are never perfectly clear (100% VLT), so that can make it difficult to know which tint to have installed to achieve your desired overall tint. How do you calculate the true VLT of your windows? A 10% VLT tint is very dark, as only 10% of exposed light passes through, whereas a film rated 75% VLT is comparatively light. The lower the VLT percentage, the darker the window. The VLT of a specific tint is given as a percentage of the visible light that passes through the window so, a tint with a VLT level of 40% means that 40% of the visible light that a window is exposed to will pass through. Vehicle window film manufacturers and installers use a measurement called the Visible Light Transmission (VLT) to gauge the darkness of a window tint.
