The charts and information listed below help to address the many questions about the Solar Spectrum and its effect on Heat and Fading. There are three main sections of the solar spectrum that generate energy coming through your windows or glass. The definitions and breakdown is listed below…

Ultraviolet (100-380 nanometers) – Invisible and energetic wavelengths made up of UV-A, UV-B and UV-C rays. While UV-C rays are filtered by the earth’s atmosphere, most people are concerned with UV-A and UV-B rays. Most films will block 99%+ of these harmful rays.

Visible Light (380-780 nanometers) – The only part of the spectrum visible to the naked eye, visible light is the one factor that most people can recognize right away. Visible light represents 44% of the sun’s radiant energy and 25% of the causes of fading.

Infrared (780-2400 nanometers) – The final segment is made of rays we can feel but not see. These invisible rays represent the largest source of the radiant energy 53% and also contribute to the causes of fading (25%).

We offer various types of window films to control each of these three factors. Consult with your C-Thru representative for the best window film that meets your specific needs.
