Ceramic Window Tint: You Might Not Have Heard of It, but You Want It
The superior properties of ceramic window tint will boost comfort and visibility with less heat and glare.
In areas where the sun shines the brightest, window films provide one of the best upgrades for controlling cabin temps and warding off skin cancer when driving during the daytime. However, ceramic window tint is significantly more effective at blocking solar energy while appearing virtually clear or lightly tinted.
In effect, it simultaneously allows the most visible light through and shuts out a large percentage of the heat-producing infrared rays. How cool is that?
Nano-ceramic window tint formulations are gaining popularity because they keep the cabin cool without resorting to darker shades discouraged by law enforcement. Moreover, they are not as expensive as you might think. The cost difference between metallic dye and ceramic is close enough, such that some window tinting shops now only install the ceramic film.
Key Benefits of Nano-Ceramic Window Tint
- Nano-tech delivers superior infrared heat rejection while appearing virtually clear and reducing glare
- Reduces the risk of skin cancer and breakdown of interior materials by blocking harmful UV rays
- Will not interfere with cellphone, satellite, or GPS navigation signals
- Limited lifetime warranty offered by top-tier manufacturers
Ceramic Window Film Explained
Scientists use nanotechnology to formulate a layered film that reflects more longer-wavelength infrared energy while allowing shorter-wavelength visible light to pass through. Consequently, it elevates heat rejection without resorting to ultra-dark shades.
Nanoparticles of ceramic can block 99% of harmful UV radiation that can cause damage to the skin and break down the interior materials of your vehicle’s cabin, not to mention rejecting a fair amount of IR rays that warm the inside of your car.
For these reasons, the Skin Cancer Foundation approves all of the brands listed in this article for reducing the risks of basal cell carcinoma, squamous cell carcinoma, melanoma, and other types of scary-sounding cancerous skin growths.
“Ceramic is one of the earth’s most timeless insulators and heat-resistant materials,” said Steven Schroer, Sales & Marketing Manager for the Americas at Solar Gard. “Take those properties and bring them down to a size where they can impact and absorb a spectrum of non-visible light associated with heat, and you greatly reduce the thermal load inside your vehicle.”
The makers of this window film were successful at creating a formula to utilize nano-ceramic compounds for improved visibility and durability. Indeed, the films also have higher color stability and superior heat rejection properties in contrast to dyed and metalized window films. While the nano-tech in ceramic window films has been around for over a decade, a few manufacturers went back into the lab and developed newer formulations with better properties.
Reasons to Tint Your Windows Using Ceramic Film
- Comfort: Strong heat rejection reduces the load on AC and electrical systems on hot days. Energy conservation becomes especially important for EV and PHEV cars.
- Health: Block the sun’s harmful UV rays that age your skin and damage the interior materials of your car.
- Maximum visibility: Lighter shades can block more heat and allow excellent visibility at all times of the day and during rowdy weather conditions.
- Style: Enhance the look of your vehicle.
- There is less glare.

A great window film for all your needs does the best of everything from heat reduction, to IR blocking, to glare and fade reduction, and includes a solid warranty that backs the product 100%.
Best Ceramic Window Tints
Here are some of the leading nano-ceramic window films on the market today.
3M Ceramic IR
3M is a company dedicated to applying science and engineering to innovative and useful solutions for over 100 years. Its humble beginnings in 1902 grew out of a small-scale mining venture in the Upper Midwest Great Lakes region, formally named Minnesota Mining and Manufacturing Company. Today, it’s a global company with hundreds of universally recognized products.
3M Crystalline is a well-known automotive window film that uses a proprietary make-up with 97% IR rejection and up to 66% total solar energy rejection, which helps ward off the heat on sunny days. It is not a ceramic-based film, but it’s still adept at impeding heat from the sun.
Consumers favor it because of its heat-rejection properties. It is also less reflective than its competitors — even with a VLT of around 70% and 80% — and is highly capable of reducing glare.
New & Improved
In 2021, 3M released its Ceramic IR Series window film based on nano-ceramic technology. This formula is brilliant at hampering total solar energy and IR rays without having to settle for an ultra-dark shade (or low VLT rating).
Since it is a ceramic-based film, GPS, radio, and cellphone signals come through cleanly while blocking 99% of damaging UV rays. Even though it has a natural sheen and gloss, Ceramic IR can reduce glare from 12% to 93% relative to the tint level.
What’s more impressive is that the cost of Ceramic IR is less than Crystalline.
3M Ceramic IR window film feels thicker than, say, LLumar’s FormulaOne Stratos ceramic film, according to a couple of installers I spoke with. The overall thickness of the material makes it more difficult to apply on surfaces with curves. Thus, a shop may recommend using a different brand if the shape of the window has too much curvature.

Deciphering the Specs
* VLT: visible light transmitted, the amount of light that can pass through the glass as well as the tint film.
** TSER: total solar energy rejected is the percentage of the total solar energy that is rejected and a good number to look at when comparing window films. Why? Because TSER includes all three: visible light, infrared, and ultraviolet.
*** IRR: the total infrared light rejected.
∞ UV rejection: the percentage of ultraviolet radiation that is present in sunlight and causes the most damage to our eyes, skin, textiles, and polymers.
¥ IRER: infrared energy rejection is a measurement of heat experienced from solar infrared radiation (780-2500nm), including absorbed and re-radiated energy. The higher the number, the more infrared energy is reflected and absorbed and then released outward. IRER is the endorsed calculation method of IWFA.
