Ceramic Window Film: Heat, UV, and Privacy without Guesswork

Ceramic tint is about IR and UV at a given VLT — not how black the glass looks.

Updated: September 2026 8 min Read Ultra Nano Shield

Overview

Ceramic automotive window film uses non-metallic ceramic particles to reject infrared heat and block UV while keeping a chosen visible light transmission. Darker is not automatically cooler. Ultra Nano Shield publishes CR70 (VLT 75%, IR rejection 75%, TSER 69%) and CR50 (VLT 50%, IR rejection 92%, TSER 89%), both 2 mil, 99% UV.

Published CR Table

Thickness 2 mil both. UV 99% both. Glare reduction is printed as 35% on CR70 and 25% on CR50 — confirm that line; it may be counter-intuitive.

Metals vs Ceramic

Metalized films can interfere with some antennas. Ceramic is sold partly to avoid that. Still test if a customer has sensitive gear.

Legal

Always check local tint law before choosing VLT. This page is not legal advice.

Summary

Read VLT, IR, TSER, and UV as separate numbers. Ultra Nano Shield already printed two ceramic grades.
