I caught the last bit of this home improvement show the other night and they were talking/showing about this stuff you can roll onto any window and it makes it a hurricane window.  They would roll it on and then they used one window a day later and hit it with a baseball bat...rather hard I must admit.  It did what you would expect a cane window to do, shattered but did not penetrate. 

I can't find anything when doing internet searches.  Anyone have any idea what I'm referring too or seen this product?  Any help is appreciated.

Almost any of the window film products will help keep broken glass in place, but there are some "special" products for it, too.  Google on "Hurricane Window Film" and you will get a lot of hits.

What it WON'T do is protect the lite of glass from being sucked out or pushed in by wind pressure because the glass deflects and would eventually break at the edge of the film or loose its bite in the framing.  Glass will deflect a lot before it breaks and one of the calculations needed in commercial facades is to insure that the glass bite is sufficient to hold a lite in place at the extremes of wind load deflection.

In order to improve that performance, the film must extend to the edge of the glass (so it is captured in the bite) or be secured to the window frame.  Most residential windows have fairly small lites and imact breakage is usually a much bigger problem than wind pressure failure, so the films should be effective.

Some of the glass in the Sears Tower was reinforced in the late 70's or early 80's with film that was attached to the window framing to minimize the possibility of a broken lite falling to the ground.

Applied films usually degrade visual quality somewhat.  The thicker the film, the better the protection, but more degradation.

The film will not be as good as real laminated glass, but would be much more effective than taping your windows......something to think about on the Gulf Coast.  My daughter's apartment in Galveston recently got trashed by a broken window during Ike and the film may have helped.
