Eisenglass 

What da "baldy from Baldymoore" U.S. prez had installed in da windows of da White House.

After installing Eisenglass in his end-of-Pennsylvania-Avenue abode, da chrome-domed 34th commander-in-chief hired folks from Middle Earth to serve as "Eisenguards" to keep folks who were less than inclined to say, "I like Ike" from lobbing rocks through said fragile silicate sheets.
