According to Wikipedia, PMMA, also known as acrylic or acrylic glass as well as by the trade names Crylux, Plexiglas, Acrylite, Lucite, and Perspex, is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass.
Our studies show huge potential for usage of PMMA for daylighting applications in buildings, but it is not easy to collect reliable information about the CO2 emissions or maybe other negative consequences of this material?
