Lighter Side Of Tint, How Infrared Window Film Works

Solar control window film has been available since the 1950’s.  The evolution of thin film technology and adhesives has vastly improved over these decades as you would expect.

Today’s high teach window films are available in many iterations that provide durable high heat rejection warranted for a lifetime of comfort and reliability.

Many consumers prefer lighter coatings that are nearly invisible to cut high temperatures without altering the aesthetic appearance of their home’s windows, doors and sliders.

The key objective is to lower cooling costs without adding any interior or exterior reflectivity. This becomes critically important for deed restricted communities or condominium associations that prohibit reflective films.

The solution required to provide this type of heat rejection without substantially darkening the windows is the implementation of IR heat rejecting films that attack the invisible wavelengths. IR wavelengths represent nearly 50% of the total solar energy.

Since visible light wavelengths represent the balance of the total solar energy a window film that combines visible and IR filtering will provide the best value for the home consumer.

Advanced Film Solutions represents the Eastman Chemical’s Huper Optik IR heat blocking solar films.

Huper Optik is available in multiple light transmissions that attack visible and IR heat.

The ceramic coatings are responsible for light filtering rather than dyes. Dyes will color migrate and fade in a short amount of time. It may also be the case where surface applied dyes are easily scratched from the film.

Petented Huper Optik is 100% dye free and the combination of visible light and IR rejection is unsurpassed in the industry.

Key FAQ’s:

  • IR heat lamp gimmicks will appear to demonstrate superior heat rejection but the sales demonstration is an illusion. Since visible light represents 50% of total solar energy any IR heat lamp demo is automatically leaving out 50% of the typical homes heat gain.

  • All window film works better when the sun is at an angle to the windows. There is no film that provides any additional capabilities compared to another at an angle.

  • Ceramic films are far more durable than dyed coatings (refer to 3M Prestige multi-layered optical films,)

Window Tinting Fact Check. Consumer Awareness Starts Here

With the political campaigns in full swing most consumers are aware that various claims and statements made by candidates are not always factually correct.

The same can be said for window film statements made by various representatives and agents for window film companies.

Fortunately consumers can get detailed performance characteristics thanks to the NFRC which is a quasi-governmental agency that is the repository for factual, lab tested specifications for leading window film brands.

The NFRC (Click here) was developed to demonstrate accuracy in light of the anticipated energy savings that would eventually lead to Energy Star ratings.

While the intention of window film manufacturers to comply with the strict testing data imposed is admirable, an unintended virtue of the NFRC is to dispel numerous exaggerations frequently espoused during competitive sales calls and demonstrations.

Advanced Film Solutions is one of Florida’s leading commercial and residential window film installation companies.

We remain steadfast in highlighting factual performance expectations and real-world film comparisons.

Here are a few examples:

IR Hype

3M Window Film dealers are known to confuse heat rejection results with Infrared filtering statistics.

For example they may claim that their Prestige Film series stops 97% of the heat from entering your windows no matter how light the film may be.

In the case of Prestige 70 the actual NFRC rating for total solar energy is 50%.

Frankly 50% heat rejection is fairly good for such a light film transmission; so where is the disconnect?

IR heat blocking films like Prestige and Huper Optik do filter out a large percentage of the IR wavelengths but IR wavelengths only effect 50% of total solar energy (Heat)

The remaining portion of heat is a factor of visible light being filtered.

If 70% of the visible light is being transmitted than a large proportion of heat is not being rejected.

On Angle Hype

To further obfuscate the NFRC rated performance a 3M agent may insist that their film performs better at an angle. They may imply that this improved heat rejection is unique to their film.

Here again this is complete nonsense.

All window films and glass itself performs exactly the same way. There is no advantage whatsoever.

Heat Lamp Trick:

If a 3M dealer wants to demonstrate an illusion of heat rejection they may employ a heat lamp that blasts large amounts of IR wavelength. They may compare a coated piece of glass and compare that to a clear glass pane or a darker coating that does not filter IR wavelengths. This gimmick gives the illusion that a lighter film like Prestige 70 can block more heat than a darker silver type film.

The facts are that a darker silver film will block 80% of the total solar energy versus the 50% stated above. The visible light is reflected in the case of reflective films.

The trick is compelling but nevertheless it remains a trick.

Advanced Film Solutions represents Eastman Chemical and their portfolio of Vista, LLumar, Huper Optik coatings.

We can also do the David Copperfield illusion or make unqualified statements about angles and IR heat rejection but we choose not to do so.

We prefer facts.

IR Heat Blocking Window Film, Facts & Fiction

Today’s consumers can enjoy the benefits of IR heat blocking window film thanks to advances in thin film technology and in particular nanotechnology.

The technical aspects aside there are confusing statements frequently made that tend to misrepresent the efficacy of these films.

Advanced Film Solutions promotes Eastman ceramic films, notably the patented Huper Optik films.  These films are available in numerous light transmissions from dark to invisible.

3M offers their Prestige series which is limited to lighter 40% – 70%

The confusion generally results from the distinction between IR wavelengths and visible light wavelengths of Sun’s electromagnetic energy.

50% of heat is produced by the visible light spectrum and roughly the same amount of heat is produced by the invisible IR wavelengths.

 

A window film that can block 100% of the IR wavelengths (there is no such animal by the way!) would still allow 50% of the visible light heat unless some mechanism was used to lower the visible light transmission.

This is a very important clarification because many misinformed window film people highlight the IR wavelength rejection as the only cogent factor for heat reduction. They may also try to support that error by demonstrating IR heat lamps that give the illusion that the IR wavelength rejection is the entire issue.

It’s the combination of IR rejection and visible light rejection that produces the most effective measures to combat heat.

This becomes a balancing act and the consumer can choose just how dark or light they want their film to be.

The NFRC has provided a valuable resource for consumers to acquire factual performance characteristics rather than sales hype or ignorance of the physics behind heat.

Advanced Film Solutions coatings are all NFRC rated and we encourage the comparisons because we appreciate that facts overcome illusion.
