Proven effect of our UV protection film
The following graphic shows the light spectrum visible to the human eye. The wave range of ultraviolet light (UV radiation for short), which is no longer visible to the human eye, begins at the left edge of the page. This range is largely responsible for the fading of objects.
The different types of UV radiation
Like visible light in different colours, UV radiation is divided into three ranges: UVA, UVB and UVC.
- UVC radiation is completely swallowed up by the earth's air envelope and does not reach the earth's surface.
- UVB radiation is partially weakened by the ozone layer of the air envelope.
- UVA radiation, like visible light, is largely transmitted by the air envelope.
| Classification of UV light according to DIN 5031 | Wavelength |
|---|---|
| UV-A | 380 nm - 315 nm |
| UV-B | 315 nm - 280 nm |
| UV-C | 280 nm - 100 nm |
Test result of our UV protection film
A UV protection film must therefore block UVA and UVB radiation for wavelengths below 380 nm so that objects behind it are protected from fading.
The graph on the left shows the measurement results of our UV protection film for wavelengths between 200 and 400 nm. The curve shows that UV rays up to 378.1 nm are blocked 100%. Only above that does the light transmission of the ultraviolet radiation increase. This results in 99.5% protection against UV radiation. Really good UV protection products are characterised by a shielding of more than 99%, conventional ones only just achieve this at best.
Theoretically, despite the protective film, rays with wavelengths > 378 nm can still affect objects behind the film. Unfortunately, 100% protection cannot be guaranteed.
