Put three tint samples next to each other and you might expect the darkest one to carry the highest number. ZIVENT’s lineup for the 2026 SEMA Show offers a good reason to read the label. The South Korean manufacturer NDFOS says its ZV70, ZV80, and ZV90 films have a similar color appearance. The numbers refer to the company’s infrared rejection ratings of 70%, 80%, and 90%.
That distinction matters at the tint counter. If a shop offers you “the 90,” ask what the number measures. In this lineup, it tells you about infrared rejection. To compare how light the windows will look and how much solar heat the film rejects overall, ask to see two other figures for the shade you’re buying: visible light transmission and total solar energy rejected. That gives you a way to compare two quotes even when the brands use entirely different names.
