1/2 Inch Tempered Glass As A Substrate...

orson

We're generating ideas for a bar top that will be lit from underneath so the surface glows. Initial idea is to set 12x12 onyx tile in clear epoxy on top of 1/2" tempered glass sitting on framing 24"OC. Does this sound like a stable substrate?

After I posted this I saw another thread here w/ a similar type of question that got shut down. I am an experienced contractor and I'm working w/ a very experienced tile subcontractor, however, this is obviously an off the beaten path application so any input from other experienced tile folks is appreciated.

I wouldn't use tempered glass- even though it's protected from above by tiles, what if it gets hit from underneath? how about plexiglass/cast acrylic sheet such as this- http://www.professionalplastics.com/...YLICSHEET-CAST

Lexan is what we've used for
bullet proof cashiers cages.
Pretty durable stuff.
Agree with Dustball about
tempered glass.

I was concerned plexiglass would not be rigid enough.

Which part of "bullet proof"
doesn't sound strong enough?

I've used 1/2" thk acrylic with vertical ribs also in plexi.
Try playing with clear and milk white plexi to determin the affect you want.
