Direct sun light tends to cause skin sensation. This sensation is mainly due to mid-IR rays. In the mid-IR range, the rays at 1450nm and 1900nm are well absorbed by human skin, and cause the sensation. Most Infra Red rays near these wavelengths can not transmit through Sekisui's solar control interlayer film.

The solar control interlayer film can transmit radio waves emitted from such as radios or cell phones. Because conventional heat reflecting glass shields those radio waves, a vehicle's windshield made of the glass may cause the failure of communication with ETC. Such problems do not occur if the solar control interlayer film is used because it does not shield radio waves at any wavelength.
