Seems even more useful than its weight. There is a lot of energy loss from the windows of buildings. Would be a huge gain if that can be brought down significantly.
Imagine leaving a house unattended in a humid or rainy area for one year, you would come back to swollen up windows which I am sure are far from clear. I guess you would have to replace these windows at least 5-10 times as often as regular glass. Also, glass is 100% recyclable whereas this would produce even more plastic waste.
Someone mentioned that this isn't weatherproof, but it could still be used for the inside plies of a triple glazed window for instance.
Yep, not much different from:
>Possibly as an inner pane(s) of sealed multi-pane windows (with traditional glass on the outside)
I mean, what is the "Or,"?
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.
