Ceramic and carbon films absorb heat and release it as you drive, with airflow helping cool the glass — this is exactly how automotive tint is designed to perform.
In extremely hot climates, especially when your car is parked in direct sunlight, you may still feel some warmth. Constant sun exposure can push any tint film to its heat-absorption limit.
Automotive tint is intentionally designed to be non-reflective for safety, so it cannot reflect heat the way commercial or architectural films do.
Because it absorbs most of the heat, once the film reaches its limit, a small amount of warmth will naturally pass through — which is normal for all automotive window films.
Our films offer strong heat rejection and perform competitively with other top brands in real-world conditions.
