Thermal conductivity isn't really relevant in window glazing materials, because nearly all of the insulation is provided by the argon in a double (or triple, or quadruple) glazing unit. Most of the recent advances in efficiency have come from improving the thermal conductivity of the frame and the use of low emissivity coatings to reduce infrared transmission.
Regarding the embodied energy, I think that the reduced durability of basically anything that isn't glass will prove fatal in most applications. We abandoned plastic smartphone screens for a reason. A glass screen might crack if you're careless, but a plastic screen will become severely scuffed in normal use.

- jtriangle 3y agoI've had very good luck with the tempered glass screen protectors and a cheap case thusfar. Broken a few of the protectors, mostly dropping my phone in parking lots, never had the screen actually break when I was using one. Also, additional upside is, any scratches are on the glass protector, so, if you get a particularly bothersome one, you can just replace the glass and you're back to brand new for way cheaper than a new screen.
