You claimed heat (infrared) was created specifically by UV:
"Ultra violet (UV) radiation is made up of two parts; UV-A infrared (Heat) and UV-B ultra violet light, which is responsible for photosynthesis (fading)"
Infrared heat does not come from UV rays, it comes from a very different (IR) portion of the spectrum. No heat is generated by UV rays, at least not the kind that would dry out materials.
And by the way, photosynthesis has nothing to do with fading. It's a photochemical reaction with chlorophyl in plants. Perhaps you meant to say "photodegradation"?
