Tempered glass both sides?

joeh | Posted in General Discussion on November 26, 2003 02:20am

Large tract home sliders, brand unknown. Double pane glass, one pane is marked as tempered, the other is not.

Are they only tempered on one side, or does the tempered mark apply to both pieces of glass in the assembled window?

    I would say both are tempered, even though only one bears the blaze.

    Glass lites are tempered for strength or safety reasons, and it would make no sense to have one lite be tempered and the other not.

    One way to find out.

      Doug, thought of that, but don't think they'd be of much use after testing.

      Pif, I think that should be the case, but how much does it take to add that little mark to the second sheet of glass?

      They're freebie job left overs, but no stinkin' papers.

        They're freebie job left overs,

        New left overs, or old left overs?  I've been salvaging sliding door glass for years and had a surprise once when the glass turned out not to be tempered.  No idea how old it was, but it was 3/16" and broke just like window glass.  Fortunately not one of the ones I used for a roof extension over my shop entrance. 

        I know, I know, not code.  But they've been up there for 5 years and no flying branch, or hail, has broken one yet.PAHS Designer/Builder- Bury it!
