Nano-Ceramic Window Tint: You Might Not Have Heard of it, But You Want It

A Boost to Comfort and Visibility with Less Heat and Glare

applying ceramic window tint

In areas where the sun shines the brightest, window tinting is one of the best upgrades for controlling the cabin temps and warding off skin cancer when driving under the midday sun. However, ceramic window film is significantly more effective at blocking solar energy while appearing virtually clear or lightly tinted. In effect, it simultaneously allows the most visible light and shuts out a large percentage of the heat-producing infrared rays. How cool is that?

Puns aside, nano-ceramic and nano-carbon 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: Nano-Ceramic Window Film

  • 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 super 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 the cabin, in addition to 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 growths of the skin.

“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.”

Makers of window film who were successful at creating a formula that utilizes nano-ceramic compounds benefit from improved visibility and durability, with higher color stability and heat rejection 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 but allowing more light 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
  • Less glare

What Makes Ceramic Window Film Special?

  • A non-metal formula that won’t block GPS navigation or electronic signals
  • Resistant to discoloration and hazing
  • Maximum IR rejection, which indicates how much heat is blocked
  • 99% UV-A and UV-B protection
  • Glare reduction
  • High-quality adhesive
  • A film thickness of about 1.5 mil
  • Limited lifetime warranty

A great window film for all your needs does the best of everything from heat reduction, to IR blocking, to glare and fade reduction. Plus, 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 mid-west 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, is less reflective than its competitors—even with a VLT of around 70 and 80—and is highly capable of reducing glare.

New and Improved

Last year, 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 and will block 99% of damaging UV rays. Even though it has a natural sheen and gloss, Ceramic IR can reduce glare up 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 that 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.

IRER ¥ 67% 67% 67% 67% 67% 66% 66%

3M prides itself on customer service and keeping its network of dealers and installers up to date on its products. In addition to the company’s in-depth test procedures and a limited lifetime warranty, a five-day installer training and certification course are available at distributor locations or an authorized 3M shop. Product support is there if you need it either over the phone with a product specialist or a dedicated website created as an added resource for the installers.

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 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, which 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
