Carbon Film

VLT (Visible Light Transmission)
This shows how much natural light passes through the film.
Lower VLT = darker appearance and more privacy.

IRR (Infrared Rejection)
This measures how much heat-causing infrared radiation is blocked.
Higher IRR = cooler interior and improved comfort.

TSER (Total Solar Energy Rejected)
This is the most important overall performance number.
It represents how much total heat from the sun (infrared + visible + UV) is rejected.
Higher TSER = better heat reduction and energy efficiency.
