How Window Tint Reduces Heat
Tint films are designed to reject solar energy before it enters your vehicle. Modern films block heat using multiple layers:
UV-blocking layers
Protect skin and interior
Infrared (IR) layers
Reduce heat from sun
Reflective layers
Some films bounce light away
The total solar energy rejected (TSER) is the most accurate way to measure heat control.
TSER Explained
Stands for Total Solar Energy Rejected
Percentage of heat energy blocked by film
High TSER = cooler interior
Ceramic and nano-ceramic films often exceed 50–60% TSER, while dyed films may only block 20–30%
IR Rejection
IR (infrared) light carries heat
Films absorb or reflect this energy
Ceramic films block 70–90% IR heat
Dyed films block almost none
Benefits of High Heat Rejection
Protects interior surfaces
Prevents tint from warping due to heat
