Film types compared
Not all window film is created equal, and different films are best specified for different use cases.
| Film Type | Heat Rejection | Glare Control | Light Transmission | Best For |
|---|---|---|---|---|
| Dyed Film | Moderate (30–45%) | Good | Reduced | Budget conservatories |
| Metalised Film | Good (45–60%) | Very good | Moderate | Older residential glazing |
| Ceramic Film | Excellent (60–70%) | Good | High — stays bright | Modern homes & offices |
| Nano-Ceramic | Excellent (65–75%) | Good | Very high | Premium installs |
How window film reduces fading.
Before we highlight the features of window film which protect items from fading we need to understand what causes fading.
UV is the biggest contributor to fading but it is not the only one. UV light actually only represents about 40% of the problem.
So what else causes fading?
UV light: ~40%
Visible light: ~25%
Heat: ~25%
Other factors: ~10% (humidity, material quality, dye fastness)
As you can see UV is only part of the problem. To control fading we need to reduce as many of these damaging elements as possible.
How can window film help prevent fading?
Typically most professional solar control films filter at least 99% UV light, we have a specialist museum grade clear film which filters 99.5% UV and our top of the range 3M Prestige filtering 99.9% The extra. protection in that final 1% might not sound like much but this is targeting the part of the light wave is the strongest contributor to fading. Small increments can have tangible results.
As we have learned above, by eliminating UV we have only tackled 40% of the problem. The good news is the visible light (how much light passes through the film, also known as visible light transmission or VLT) and heat can also be reduced with window film.
If you a keen to lower visible light levels in pursuit of further fade protection then the good news is you will liekly reduce heat too. Most window films which lower VLT will be solar control window films, these offer a combination by lowering visible light, reducing heat and also blocking UV.
Much of the decision around which film will be best for you will be subjective. Often appearance plays a critical role when choosing window film in homes. I expect you are not prepared to reduce vast amounts of natural light or change the aesthetic of the property. And, rightly so but this does not mean yo ucannot achieve good levels of fade protection.
3M Prestige Sun Control Window Films for fade protection.
