UV Film – UV400 Technology

UV film (UV400) with extreme heat rejections 

UV400 films in our collection, cutting-edge technology in the solar film industry. These UV400 films reject 100% of all types of UV rays up to the topmost 400nm wavelength which is different from standard nano-ceramic solar films that reject UV99.99% at only below 380nm wavelength.  UV is electromagnetic radiation with wavelengths 10nm to 400nm. These waves are shorter than visible light and longer than x-rays that penetrate easily into our bodies.


  • 380-400 nm wavelength (UVT): harmful UVT Transferred without any absorbance by ozone layers. This causes skin cancer, damage to eye parts, a faster aging process (skin). Standard solar films with 99% UV rejection don’t cut these wavelength UV spectrums.
  • 315-380 nm wavelength (UVA):  Deep penetrating UVA emitted in this wavelength without being blocked by the ozone layer. This UVA makes the aging process fast. It enters the skin deeply and makes the skin age.
  • 280-315 nm Wavelengths (UVB): during clear sky days, the UVB rays are not partly absorbed by the ozone. So when UVB reaches our body, it creates skin problems like sunburns, faster aging, snow blindness, and even skin cancer.
  • 100-280 nm Wavelengths (UVC):  UVC is released in this wavelength and it is mostly absorbed by the clouds. So we are usually not much affected by these rays.


Singapore is having topmost UV levels (UV Index 12 & 13) than other countries. For reference, please refer WHO UV index


These UV films can eliminate all UV rays from Sun entering through the glass panels. Usual window films with UV rejection mentioned 99.99% work only on certain wavelengths, say 280nm to 380nm. Beyond this wavelength, the standard films are not able to block all kinds of UV spectrums. Overexposure to UV rays can cause severe damage to both skin and eyes. It can also lead to skin cancer if exposed for a long period of time. These new UV400 series films can eliminate all UVA, UVB & UVC at any wavelength, and the UV values measured at 400nm is 0%.

Additional Benefits compared to Nano-ceramic Heat Rejection Films:

  • Safeguard from skin cancer. This is necessary for Singapore homes since the rooms are getting smaller and window glass panels are getting bigger means we get UV higher volume & faster rate inside the room. Standard Nano-ceramic solar films are not sufficient to reject UVA at higher wavelengths.
  • Our UV films come with very high heat rejection properties the same as other high-end Nano-ceramic films. This means you are getting very important additional benefits in one window film purchase.
  • UV rays are more vulnerable to infants, children, and old aged. Highly recommended to buy UV films.
  • Those with high-quality carpets and furniture at home to avoid fading need this UV film compared to the standard.
  • Especially needed for eyes when your room is direct exposure to sunlight. Our retina is more sensitive to UV and UVA can easily penetrate to change cells in the retina. We are happy to say SGH has specially installed our films for their eye bank and retina testing areas.
