James,
After the Sandy Hook tragedy I got thinking of my own personal security . From limited information in the press the perpetrator came though the window because the doors were locked . After sending a few rounds through the tempered glass , the glass pulverized and he simply stepped though and started his killing spree . Question , where was the window located ? If it was a side-light to the door then it would be a double paned tempered glass window . Question, if it was a side-light window why no laminated wire mesh? That would have slowed him down trying to bust out the mesh . Was it a standard school window with all it’s double paned shards of glass. As you can see so many questions and no answers yet.
We are a nation of glass . We use glass in our homes ,schools, hospital, offices, but just how secure is glass? Safety glass is not security glass , the very nature of tempered glass makes it poor for security . I just installed two security doors but right next to the doors is floor to ceiling glass, now what do I do. Below is a link to a video of a fellow walking through 15 panes of tempered glass in little over one second each. As a nation we need a low cost solution to this glass problem. – Matt in the Evergreen State
