Archidose:

The story linked above guesses that the cost to replace the glass will be $450,000, based on the bill for renovating the cube in 2011, when it changed from 18 panes per side to 3. Considering that each pane is made up of (I think) 5 layers of ~10’x32’ tempered glass laminated to each other, this cost does not seem surprising.

Damn…
