The texture has nothing to do with whether or no it's safety glass.

I use a small mirror and a flashlight to see etchings that are too subtle for me to see unaided. If I can't see the etching, I say that I couldn't see an etching and to replace it with safety glass that does have an etching. If someone wants to argue with me, I invite them to show me the etching. On two occasions, others have found the etching where I missed it. (That's when I started using the mirror.)

The other alternative is to use a BB gun. (See, I told you it wasn't tempered. . . )

Does anyone know when the requirement for safety glass in shower enclosures was introduced? It occurs to me that this is likely in an older home, which may have pre-dated the safety glass requirement.

(I'm getting the shower scene of Hitchcock's "The Birds" in my head now)

Take comfort in the fact that in today's market, products made for buildings are required by codes to be listed for the use they serve. I don't think you would ever find a bootleg non-tempered shower door/enclosure.

"I use a small mirror and a flashlight to see etchings that are too subtle for me to see unaided."

Please elaborate.

I carry a small mirror, the size of a business card. Place the mirror against and perpendicular to the glass and use the flashlight to shine a grazing light against the glass. The mirror will often show the etching where I couldn't otherwise see it.

Of course, the etching will only be on the smooth side on pebbled glass. You might have to go outdoors to look on the other side.

Are these scratches the etchings you speak of?

Do you have a picture? This photo is from a large shower enclosure in a pretty fine home. I used to write up that I could not be sure if shower glass was tempered if it wasn't marked but stopped doing that a long time ago.

I tried the mirror technique you spoke of but didn't see how that made any difference in what I was looking at.

I believe the requirement for tempered glass adjacent to bathtubs was first required in the 1996 IRC. I see many houses without tempered glass there. My own house was built in 1990 and did not have it until I replaced the window. Many replacement window companies still don't install tempered glass.

I think you mean CABO.

The requirement is much older, though. It's in the 1979 CABO and in the '76 UBC. (Those are the oldest ones I've got.) But I suspect that it first showed up in the early '70s.

"ICBO's Uniform Building Code 1961 edition was the first to require safety glazing for shower doors."

IRC inaugural edition was Y2K. Before that we were SBCCI, which used CABO for residential.

Because it's costs money. Tempered glass is cheap for new construction standard sizes built by the thousand. Not so much for custom replacementsoftware built one at a time.

If no permits are required, consumers don't know they need it. I always recommended it, but people would rather spend $20 a lite for grids than $100 a sash on safety.
