Understanding Ceramic Window Tint Technology
Ceramic window tint represents a significant upgrade over traditional dyed or metallic film options, using microscopic ceramic particles to block infrared radiation without the drawbacks of older technologies. The performance of ceramic window tints is often subject to rigorous testing protocols to ensure heat rejection and clarity. This advancement has positioned ceramic tint as the preferred choice for vehicle owners prioritizing both performance and electronic compatibility.
Nano-Ceramic Construction
The ceramic construction of SunTek CIR embeds microscopic ceramic nanoparticles throughout a multi-layer polyester substrate. These particles, invisible to the naked eye, absorb and dissipate solar infrared energy before it enters your car’s cabin.
SunTek’s marketing references the heat-shielding ceramics used on the Space Shuttle during atmospheric re-entry—a fitting comparison given that both applications harness ceramic material properties to manage extreme thermal loads. The nano-ceramic particles in the CIR target absorb infrared wavelengths between 780 and 2500 nanometers, which carry the primary heat energy from sunlight.
Non-Metal Composition Benefits
Unlike older metalized films that reflect radio frequencies, SunTek CIR’s metal-free composition eliminates signal interference entirely. Your GPS navigation, satellite radio, cellular phone, keyless entry systems, and tire pressure monitoring systems work without degradation.
This non-metallic approach solves a persistent problem with earlier-generation window film products. Metal-dyed tints from the 1980s and 1990s often disrupted electronics, making ceramic tint especially relevant as vehicles incorporate more connected technology and drivers depend on seamless phone and navigation performance.
Selective Infrared Rejection (SIRR)
Selective Infrared Rejection measures how effectively window film blocks heat-carrying infrared wavelengths while allowing visible light transmission. SunTek CIR achieves up to 84% selective infrared rejection, as measured by spectrometry in accordance with industry standards such as ASTM E903.
The number representing visible light transmission (VLT) or infrared rejection is a key specification when selecting window tint. This selectivity means CIR reduces cabin heat without requiring an extremely dark tint. Understanding these measurements helps you choose the right visible light transmission level for your needs and local regulations.
