## 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

#### Keeps cabin cooler

#### Reduces A/C usage

#### Protects interior surfaces

#### Improves driver comfort

#### Prevents tint from warping due to heat
