Hyundai's Nano Cooling Film Is Set To Revolutionize Window Tints

Hyundai is showcasing its material research prowess by coming up with the world’s first application of “Nano Cooling Film.” It’s a revolutionary new window tint that offers significant improvement in interior cooling performance compared to conventional tint films.

First launched in South Asia markets such as Pakistan and expected to be rolled out in other markets that experience hot climates (it may include the Philippines), the Nano Cooling Film maximizes heat dissipation by incorporating a nanostructure with excellent heat transfer characteristics. This transparent film is expected to be more effective in hot and dry climates, as the cooling effect is optimized at higher outdoor temperatures.

Hyundai says it surpasses conventional tint films in its ability to block heat while maintaining high transparency and unobstructed vision. Unlike dark tint shades that can negatively impact nighttime visibility and release absorbed heat into the vehicle, Nano Cooling Film effectively blocks external heat energy and emits internal radiant heat to the outside. This is achieved through its unique composition of three layers that selectively block or emit specific wavelengths of solar heat.

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.

In addition, the Nano Cooling Film can be applied in tandem with conventional tint films in countries where car tints are less regulated. If regular tint films are added on the back side of the Nano Cooling Film, the overall heat reflection and radiation are enhanced, resulting in greater cooling effects.

Hyundai’s experiments with Nano Cooling Film have confirmed its effectiveness. In a study comparing the interior temperature of vehicles during daylight hours in the summer, it was found that Nano Cooling Film reduced the temperature near the driver’s head by up to 10.98 degrees Celsius compared to conventional tint film, and up to 12.33 degrees Celsius compared to the same vehicle without window tinting. Additionally, the dashboard (crash pad) temperature of the vehicle with Nano Cooling Film was 15.38 degrees Celsius lower than the same vehicle with conventional tinting, and 22 degrees Celsius lower than the same vehicle without tinting.
