Here’s What We Know about Hyundai’s New Window Film So Far

July 3rd, 2024 by Casey Flores

Large consumer brands have tried adding window film to their repertoire  before—but never by a company as globally recognizable as Hyundai.

The almost $50 billion Seoul-based auto manufacturer announced in April it would be getting into the window film industry with its “Nano Cooling Film” product.

Hyundai spokesperson Dain Kang says the company chose window film because as “the trend in vehicle design moves towards increasing glass surface area, glass has been identified as a major contributor to thermal load inside vehicles” and that “Hyundai Motor Company has focused on new materials to be applied to the glass.”

King isn’t specifying what markets the company will be targeting with its film nor whether Hyundai is manufacturing the film itself or private labeling.

“Hyundai Motor Company expects to enter mass production of this technology, but nothing has been decided yet,” he says.

In its initial release, Hyundai said the product is a “revolutionary vehicle window tint that offers a significant improvement in interior cooling performance compared to conventional tint films.”

King provided Window Film magazine with data from the film’s testing.

“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 [19.74°F] compared to conventional tint film, and up to [22.19°F] compared to the same vehicle without ]window tinting,” he says. “Additionally, the crash pad temperature of the vehicle with Nano Cooling Film was [27.58°F] lower than the same vehicle with conventional tinting, and [39.6°F] lower than the same vehicle without tinting.”

Darrell Smith, executive director of the International Window Film Association, says it’ll be tough for Hyundai to offer its own film at its dealerships.

“You don’t see the other manufacturers selling directly to car dealerships,” Smith says, noting it isn’t clear how Hyundai plans to distribute the film yet.

“There’s a potential legal issue. They may decide to make a window film, but they can’t sell their new cars with the window film on it,” like they do in Asia where vehicle glass comes transparent—not pre-darkened like it does in North America, Smith says. “They have to be making it to install it as an aftermarket sale separate from the original vehicle sale.”

Regarding its visible light transmittance range, whether they’ll be hiring separate sales representatives, and even marketing the film at major trade shows, Kang says “nothing has been decided yet.”
