I would phone a local glass shop to see if they have exactly what you want.

I bought clear matte finish plastic/acrylic sheets from an art & pic frame place several years ago because of quakes so my pics wouldn't get damaged if they hit the floor. They are nice & still using them. The non-glare feature is nice So I would Google in "Non-glare acrylic picture frame "glass" I don't know what else it's called. You have to clean with damp cloth not Windex type products or will dull them. Hope this helps! Jan
