Same stuff, varying qualities. Most cheap extruded acrylic comes from China and it's useless. Quality acrylic usually has a name on the cover. Plexiglas is a trade name for the Rohm & Haas product, while other companies make different brands like Perspex or Acrylite. I have never heard of a UV-protected acrylic in sheet form except for museum-grade, which is generally too thin for glazing and really designed more for artwork protection. Lexan (Makrolon) is available UV-protected because it doesn't have the same UV stability of cast acrylic.
More to the point, I used cast 2404 for our windows, you can see white sealant through it, and they show no sign of distress after 6 years. Novus products work really well to remove hazing and scratches.
