Any suggestions?
New Number: 08 88 53 Structural Glass Flooring
Ron - the MF “bible” has 08 88 53 as Security Glazing
Oops! I stopped looking when I reached the line.
Change that to: 08 88 59 
Just a simple question-- would there not be a case for placing this in 09 since it is a flooring system-- perhaps as another “Specialty Flooring”?
I thought about that, but Division 09 is finishes, and even though the glass flooring has a finish, it isn’t just a finish.
Glass used in a floor system really isn’t any different that glass used in a wall system–it’s an opening in a floor rather than a wall. The main difference is that it has to support a different type of load.
Therefore, my choice for location is Division 08.
Can’t quarrel with that.
I just came from the thought that wood flooring is in 09 and not 06, not so much as a finish, per se, but as a system.
Quick uneducated thought was to equate glass to wood in this example.
most of the items in Division 9 only have to support themselves and incidental loads. While wood flooring does have to support whatever is standing on it, the ultimate support is the subfloor, not the floor “veneer” (which is a very good thing if you’re talking about carpet). Glass flooring is more like a skylight in the aspect that it has to have its own structural characteristics and support system for its own and incidental loads.
However, if you had glass that was just sitting on top of the subfloor, sort of like a tranparent veneer, then Ralph would probably be correct.
My vote is for Division 8, more specifically 084. The material and fabrication issues are similar to those for structural glass curtain walls. The suppliers of the glass would also be the same.
4specs lists glass flooring under 096240 Glass Flooring and Framing. Of the 12 manufacturers listed here, only two are among the 11 manufacturers listed under 084420 Structural Glass Curtain Walls. Many of those listed under 096240 are art glass manufacturers.
Hey…since glass block is in the masonry section, let’s put structural glass flooring in the concrete section!!
I’M KIDDING!!
So. . .if you have a glass interior wall does it go in division 9 as a finish? My vote (are we voting yet?) is division 8; I tend to focus, in this case, on the word “glass” rather than flooring; for some of the reasons Anne gives. By changing focus on which characteristic is most significant we can come to different divisions (flooring = 09; glass = 08).
If the focus is on flooring then concrete slab on grade should be moved to Division 9.
How about something like this?
G= glass W= wood veneer C= concrete
Basic Mat’l G08 W06 C03
Part of system G08 W06 C03
Self-contained G08 W-n/a C03
Flooring G09 W09 C03
Supported floor G09 W09 C-n/a
In other words, where used “as itself” the mat’l stays in basic Div. When used in conjunction with other elements, would move to other appropriate Div. that reflects combination of materials.
I’m going to hide behind my big chocolate bunny now, so the MF04 Task Force can’t find me!
you’ve been found!
Somebody must have eaten the ears…
