What is Protecting Our Nation?
Dear Window Film:
I have read the recent article “Business the Hard Way” in the November-December 2001 issue numerous times now (see page 22). I read it each time with great interest as well as concern.
Your article says how film companies and attachment system companies are working 24-7 to meet the demands of the federal government. I think that’s great for the industry as a whole!
But I have to wonder, what types and thickness of films are actually being utilized? I recall reading an article concerning the Protective Glazing Council (PGC) and how the federal government was not satisfied with the performance of a 7- or 8-mil film for glass mitigation. And we all know that a 4-mil film is not intended for glass mitigation. So, have we actually graduated to using the thicker 3-ply, 11- or 12-mil films? And if they are actually are using the thicker films, then where do the attachment system companies come into play?
I know that is extremely difficult to get a 7- or 8-mil film to crease 90 degrees at the frame and wrap around a metal bar, and that getting a 11- or 12-mil film to do the same is virtually impossible. But okay, so the government said put up a 7-mil film with the attachment system. And they are accepting a 2-sided system. That still raises a couple of questions. If that 90 crease at the frame isn’t perfect every time, is there not a void created in the film? And, don’t the holes through the film and frame work for the screws used in a mechanical system weaken the integrity of the film and the frame work? And what about a 4-sided mechanical system? How can you possibly install the film, overlap all four sides and work through the corners without cutting the film? Cuts in film say void in integrity to me.
So given the fact that the performance of the 7- or 8-mil films may not be enough in glass mitigation, possible voids in integrity of film and frame work from screw holes with mechanical attachment systems, and the inability to utilize a heavy film (11 or 12 mil) with the mechanical systems, not to mention that not too many film applicators can actually put up the heavy films, I pose this question: What exactly is our nation being protected with?
