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.
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.
