Hi there,

I've never done a project like this before, so I'd love to hear your advice on the framing idea below.

My customer has a stretched canvas measuring 23" x 35" and 2 3/8" thick, and he wants it framed behind glass because his children are constantly touching it. We don't want to take it off the bars. I was thinking of mounting it like the example in the picture attached, but I'm not sure what the backing is made of. Would it be safe to use plywood board + a layer of Gatorboard to buffer + a mat board and screw it onto that?

Also not sure if I need to go stack frames like you see in the picture, so possibly will get back on that later :)

Thanks for your help!

Sure, plywood would work, along with a matboard to cover--it'll be sturdy but add a good bit of weight to the frame. You might even be able to get away with just gatorboard and matboard. Perhaps just use a washer so the screw doesn't pull all the way through the gatorboard.

That is a pretty deep canvas, so yeah the likelihood of stacking frames is high depending on what they like. Otherwise, the easiest solution would be find a shadowbox about 3" deep or more, so you have room for glass clearance and the backing boards.

If it were shallower, I might have suggested use a canvas float frame along with a shadowbox frame, and just pinch the glass between as you nest them together.
 
Does he want more space around the canvas? I would use a smaller frame, doesn't need to be deep. Put that around the stretched canvas. Glass on top of that, cap it with a shadowbox frame

Otherwise you are pretty much stuck to a floater frame, put glass on top of that and use a shadowbox frame to cap that.

As for backing, I have used matboard glued to coroplast and screwed in from behind into the stretcher bars. Works well. Just measure carefully :)

I used to make floaters that way all the time before there were lots of floater mouldings available. I would still do that it I wanted to use glazing with the floater look.
