"I recall seeing a vídeo some time ago about a Florida inventor that came up with a special glass that could withstand hurricane-driven debris hitting windows. I wonder if it ever went to market?"
it is generally called 'hurricane glass" and it is just a sandwich of two thin glass panels(for scratch resistance) two layers of a plastic adhesive film, and one center layer of lexan or plexiglass, which is the actual structural part.

A car windshield is very similar, two layers of safety glass which shatters on impact and turns into thousands of small sharp pebbles instead of the large "daggers" that plain glass would become.

No magic to either one, any real commercial glazier or plastics fabricator can make up sandwiched layers like that. Sit down and hold your breath before you call them to ask for a price.

Scotchshield is a thin film ( about 2 mils?) of polycarbonate, like lexan, with a water based adhesive. It goes on like any window film but it is designed to remain bonded with glass, so that if a bomb goes off in front of your office, the big windows crumple instead of turning into a thousand sharp bullets. Literally.

Lexan MR10 (Mar Resistant) is the commercial Lexan product that comes with a similar anti-scratch and anti-UV film already bonded onto one side. It is used in railway car windows, which are required to be bullet-resistant. Costs more than plain Lexan but resists scratching more, and the film can be removed with heat and ammonia fumes and then replaced.

There's all sorts of good stuff for the asking and you could of course even have an inch-thick tempered safety glass panel made up. But tempering glass requires special ovens after it has been cut, and there are very few places that would do that.

Boatbuilders use plexi and polycarbonate because they are the simplest cheapest way to get a reasonable job done. If you've got deep pockets and want something all means.
