Total Solar Energy Rejection measures how much solar energy is blocked, including visible light, infrared, and UV radiation.

Infrared Rejection specifically measures how much heat-producing infrared radiation is blocked by the film.

UV Rejection protects against harmful ultraviolet radiation that causes skin damage and interior fading.
