WINCOS Automotive Film


An automotive film cannot be chosen simply by its color, especially for premium cars where functionality is extremely important. With natural look, comfort and high functionality backed by scientific data, a high-grade and high-functionality premium brand is born. Experience this look into a new world of beauty and comfort.


Excellent heat-insulation effect

Leveraging the experience cultivated over the years as an automotive film manufacturer, the creators returned to the design table and created this product from scratch realizing high heat-insulation performance never before seen.

Results of car interior temperature change test

Even under low external temperatures, there is a 10 degree Celsius difference between cars with and without film.

Test Environment
– Test Date: April 2007
– Weather: Partially cloudy
– Climate: Highest temperature at 17 degree Celsius; Lowest temperature at 4 degree Celsius
– Test Duration: 9am to 5pm with measurements taken every hour
– Thermometer Used: With temperature recording functionality
– Test Subject: RV
– Test Area: Rear glass
– Film Used: HCN-70
UV-reduction effects

The energy ratio of sunlight is approximately: 5% UV rays (wavelength 280 to 380nm), 45% visible light (380 to 780nm), and 50% near infrared rays (780 to 2,500nm). Regular window films on the market generally reduce visible light and infrared rays greatly in order to achieve heat-insulation effect (1nm=1/1,000µm). The WINCOS Automotive Film Premium Series, however, mainly reduces invisible infrared rays, retaining high visibility while achieving outstanding heat-insulation performance.
* Values measured on film applied to 3mm clear float glass

  • * Based on automotive film standard JIS S 3107
  • * Shading coefficient refers to the ratio of solar gain from direct sunlight passing through the glass applied with different types of films to the solar energy which passes through a 3mm float glass with the float glass assigned a value of 1.00
  • * Heat transmission coefficient refers to the heat transfer between two sides of a float glass panel (with film applied) where the temperature difference starts at 1 degree Celsius, and measures the value change for each square meter per hour
  • * Near infrared reduction rate is tested based on the company’s specialized testing method deducting the penetration rate of wavelengths between 1,500mm and 2,200mm from 100%
  • * Solar Heat Gain Coefficient refers to the amount of solar energy penetrating the interior of a room as a percentage of the total amount of solar energy applied on the glass
  • * Values presented in this data are measured values during tests and not guaranteed values
