Agree with Seabornman,

Unless you know without a doubt that the glass is tempered, DO NOT use in that application. It's against code and very dangerous.

Not a good idea for the reasons mentioned above.

Nope.

OK, will check about the tempered glass. Wasn't sure on that part. These are supposed to withstand winds up to 60mph. I preferred a rope railing, need to check code on that too, but also wanted to cut some wind there. Thanks everyone.

look for a logo on the glass surface that says tempered. If there isn't a logo then safely break one.

If it breaks into big sharp shards of glass then don't use them. If it breaks into tiny cubes then it's tempered.

Per Home Depot, the replacement glass is non tempered. These panes are very old. Is there a way to find out if tempered? Maybe break one? My alternative was rope, which I have to still check on code. Or, a canvas panel which I really like. View is not a problem, it is wind that I would like to cut down on.

I have never known Jalousie window glass to be tempered as far as I known it was always just plain plate glass.

Every piece of modern tempered glass has a marking permanently fused into the glass like so: an alternative is laminated glass, for which you would see a seam in the center of the glass.

I have also never seen tempered Jalousie window glass but you never know until you check. I would say that if the replacement glass isn't tempered then there is virtually no chance that the older glass is tempered.

I like the canvas idea. I think that would be an option worth looking at

Curiously, and really just trivia not related to the original question of this thread, but the information concerning Cat 2 / Class A and Cat 1 / Class B designations pertains specifically to laminated glass only and not to tempered glass, but oddly the picture on the right shows a simulated tempered glass logo.
