Safety glazing can mean laminated or tempered glass. You should ask
the insurance agent what they really want.


Vic....what is your experience with lami or tempered when hit with rocks,
pellets, BB's, etc.? Aren't we looking at breakage where the Lexan
wouldn't break? I'm not so sure that the non-yellowing aspects of the
glass safety glazing is all that valuable when compared with the vandal
resistance of the plastic?

I'm really interested in your take on all this. Thanks.

Lexan will take the biggest impact. But it can be melted with a Bic
lighter. Lexan only has a 10year warranty against yellowing,the same
as 20 years ago. It is hard to clean and will scratch. A piece of
48"x60" Lexan needs 3/4" edge engagement and a 1 1/16" deep rabbet. So
you better build a good framing system. Don't for get to ventilate the
system.

Lami looks better. Won't yellow. But is heavy and should get a frame to
hold it. If you frame it properly you can replace broken pieces without
removing all the glazing. It has a higher R value, has more sound
deadening and cuts out 99% UV light. It's not as strong as Lexan, but
it takes a heavy rock to break a car windshield, and it still does not
hit the driver.

The pricing for either one is about the same.
