Dear Glass Detective:
I’m working on a novel and am in search of education on windows for a scene I’d like to create. It involves a high art jewelry designer who works out of a studio in her home. The room is 40 feet long. It faces East. I’d like to have several large windows to bring in the morning light and show the view of Lake George in Upstate New York. The windows would need to be of sufficient strength to provide unquestionable security. The character has a safe, but the content of the room (equipment, tools etc.) is still of great value. My uneducated ponderance… would it be possible to have a several layers thick laminate glass as a sturdy deterrent to thieves? I appreciate your help. Oh and I love the Holmesian attire detective.

Thank you for contacting the Glass Detective with your question about what glass would be appropriate for security purposes when valuables are involved. Given the scenario you describe, a good glass professional (similar albeit not identical to the Glass Detective) would recommend the use of heavy laminated glass panels pretty much identical to what is used in “hurricane zones”. This is what is known as “impact glazing.” If maximum security is desired, “bullet-resistant glass” which is typically four to five layers thick with heavy PVB interlayers between the glass panes, could also be used. The framing for these systems is also custom to accommodate the thickness of the panel and also the weight (often 1-3/16” thick at 16-17 lbs/sq. ft.) of the glass.
Another option would be compositions made of polycarbonate and glass. These glass-clad polycarbonates are lighter and often used in security applications such as jails and prisons. Size limitations could prevent it from being a good selection for a large room with oversized windows. So I’ll stay with the multiple layered laminated glass (impact-resistant glazing) as my choice.
As for your comment regarding the Glass Detective’s “Holmesian attire”, that was not his idea. The Glass Detective actually likes to think of himself as more of a Columbo-type. However, his grandchildren believe he is more of a Clouseau-type. Good luck with the novel, Cathleen, and when your novel becomes a movie and they are looking for the guy to play the detective that analyzes the glass, I’m available and work cheap. I hope this is of some help to you and thank you again for contacting Glass.com.
