I've seen this thing smashed out in like 3 different SW series, what's up with that? It's like the Padme "push one button to make anything work" situation, how many more times does Palpatine's window need to be smashed out before he replaces it with a Beskar'gam wall in order to stay safe?
He probably doesn't care how many times his window is smashed. He probably only has a window so he can throw people out of it when he's bored.
It's not real glass! It's a hologram to make it look like you are busting out the chancellors window...in truth, there is no window in Palpatine's office. Mace didn't fly out into the city, he was transported into a secret holographic world of terror.
When I saw the tread title, I immediately thought it would be a discussion of why a lightsaber was able to shatter it, whether it was glass or transparisteel. That seems like a far more apt question...
2) General Grievous smashed it in when he kidnapped Palpatine in LoE. 3) Clone troopers broke into it for no reason at all, when Cad Bane was holding senators hostage in an episode of CWA. This was stupid!
Those're three different windows, actually; Palpatine was in his apartment in 500 Republica in LoE and in TCW he was in the Senate building for some reason. Though the office was identical to his regular office, in the executive building.
Don't forget that time Mas Amedda got totally hammered and Orn Free Taa dared him to throw a chair through it. That was awesome.
One would expect a Chancellor's office would have something decent, like transparisteel. But for some reason it brakes too easily. Maybe it has been broken so many times that by the time in ROTS when Mace flies out, they have decided that it was probably too expensive to replace the transparisteel over and over again, so they used simple glass. *shrugs*
Maybe Palps liked it because people could get in. It helped reinforce the image of Palpatine as a vulerable old man. As Sidious though, he knows he can handle anything that comes through. Besides, he probably either planned whatever comes through or saw it coming in the Force days before it happens.
Maybe transparisteel just doesn't exist in the movies... or even the Clone Wars micro-series(a clone fired a rocket through the windows on a turbolift, if that were transparisteel he'd have been killing the people inside that turbolift). Remember, Obi-Wan simply lept through the windows of Padme's apartment in AOTC.
lol. Personally who knows what the IU explanation for the window is. I guess Lucas by de facto deems it glass since it so easily breaks with everything. But I think in RotS Lucas just wanted a "cool part" to break the window open and used it as a plot device for Mace's demise. Meh.
I guess we now know why in Betrayal he threw his Sith Lightning at the rogue Stormtroopers at the very moment the window was shot at.
One could say that, like all tissues are Kleenex, the term "transparisteel" has been colloquially broadened to include all transparent window materials, and the cases of shattering "transparisteel" are really some other, non-metallic material -- basically glass or plastic. It's conceivable real glass could be a status symbol, and some type of plastic or bulletproof glass is used in applications calling for more than cheap transparisteel foil but less than full protective panes of transparent metal.
