Whether applied to automobiles or buildings, these thin layers of film are designed to improve your windows’ performance by rejecting solar heat gain and in doing so, offer a multitude of benefits including increased privacy, improved energy efficiency and creating a comfortable indoor environment for the occupants.
To truly appreciate the value and operation of window films, it is important to grasp the concepts of Infrared Radiationt, Visible Light Transmittance and Ultraviolet rays which will ultimately dictate its Total Solar Energy Rejection specification.
The solar spectrum is made up of Infrared Radiation, Visible light and Ultraviolet rays, all of which account approximately 54%, 43% and 3% of the total solar energy from the sun respectively. The solar films’ ability to reject (either by absorbing or reflecting) these types of solar energy ultimately dictate the film’s performance (i.e., Total Solar Energy Rejection specification) – the higher the TSER of the film, the better its performance.
When choosing the right solar control film, it is best to compare the TSER specification with the same Visible Light transmission index.
