Very interesting (as a new material).

It being not waterproof/waterresistant (unless painted) doesn't seem to make it a good glass replacement for windows, though.

Possibly as an inner pane(s) of sealed multi-pane windows (with traditional glass on the outside) as - also - since it can be cut with ordinary rotary tools, it probably is not scratch resistant.

The light weight seems to me like the most relevant feature.
