How thick are the international space station windows?
Not the cupola, I've already come across a million articles on that and I'm tired of it so I came here in hopes someone would know about the other porthole windows.
Thanks.
Specifically, I'm trying to find details on the design b/c I'm designing a hypothetical inflatable habitat with windows and I can't find any details on windows for the ISS besides the cupola thing they now have and even that has sparse details.

The only windows on the ISS are in the Cupola module. The windows are made up of 4 panes. There are two pressure panes made up of fused silica glass, which are each 1.45in thick in the top window and 1in thick in the sides. There is an outer debris pane made up of fused silica glass that is .37in thick, and an internal scratch pane made up of borosilicate glass that is .44in thick. Overall, you have 2.81 in of glass (not counting spaces inbetween panes) on the side windows, and 3.71in of glass at the top.
