Hyundai Develops High-Cooling Transparent Window Tint

Korean automaker Hyundai developed its own Nano Cooling Film window tint solution that promises greater cooling abilities whilst remaining transparent.

Korean automaker Hyundai revealed this week that it has developed its very own window tint solution. Dubbed as 'Nano Cooling Film', the automaker claims that its very own tint film has better cooling abilities and performance over conventional window tints.

According to Hyundai, its Nano Cooling Film was designed to block external heat energy and emit internal radiant heat outside. Whilst that sounds like any regular tint, the promise of doing so WITHOUT reducing overall transparency – the later to allow unobstructed vision – sees this tech stand out.

“The film’s outer layer radiates heat at mid-infrared wavelengths from the interior of the vehicle to the exterior, while the inner two layers reflect incoming heat at near-infrared wavelengths, reducing the total amount of heat that reaches the inside of the vehicle,” explains Hyundai.

Hyundai says the outer layer of its Nano Cooling Film radiates heat at mid-infrared wavelengths, whilst a dual inner-layer reflects incoming heat at near-infrared wavelengths.

Unlike regular aftermarket tints, the high heat-rejection abilities mentioned comes without reducing transparency, thus keeping visibility high at all times. This is also nifty for markets with stiff. window tint regs.

To show its effectiveness, Hyundai went as far as performing real world tests by fitting 70 customer vehicles in Lahore, Pakistan recent with its Nano Cooling Film. Besides daily temperatures peaking as high as 50° C, the fact that Pakistan bans regular window tints altogether adds to the challenge.

As tests in Pakistan just began, Hyundai said previous tests “found that Nano Cooling Film can lower the temperature near the driver’s head by up to 10.98° C compared to conventional tint film, and up to 12.33° C compared to the same vehicle without window tinting.” 

It also adds that the film is even more effective at reducing interior surface temperatures, lowering crash pad temperature readouts by 15.38° C as opposed to a vehicle primed with conventional tint, and up to  22° C compared to a vehicle without any tint.

Recently, Hyundai elected to test its Nano Cooling Film under real-world conditions in Lahore, Pakistan. Daily temperatures peaks as high as 50° C, and Pakistani laws forbid vehicles from having dark tinted windows.

The latest tests performed by Hyundai in Pakistan aims to ensure the film’s quality and ability to handle real-world conditions. In other words, this could be the final round of tests for the tech before the Korean automaking giant begins mass-producing this it in the near future.

Hyundai didn’t specify a timeframe for the latter plans, but did note how its Nano Cooling Film can be applied in combination with conventional aftermarket tints for even better results. In other words, you can still apply a layer of tint from your preferred supplier on top of the Nano Cooling Film for even greater cooling.

We’re certain we may soon see future Hyundai – and perhaps Kia – vehicles sold with the option to fit this Nano Cooling Film. Given its cooling abilities sans reduction in transparency, this might just work in markets with stiff window tints regulations and high temperatures.
