What do most of you use when mounting art behind a Mat Window? Do you prefer to mount art on another piece of Mat Board or Foam Core and why? I see people do it both ways. Is it just a matter of preference?

I always use matboard. I usually have lots of offcuts to use for this purpose. Or for bigger things,
matboard you are a tad overstocked with. Sometimes you can get end-of-line bargains. Color doesn't
matter. Always hinge to the unfaced side.
I would never use foamboard for bookmats. Too thick and insubstantial.

I believe it is a matter of preference and dependent upon the type of framing it is. I like the 1/8 acid free foam board or coroplast for the common framing that doesn't need much adherence to Conservation type framing. Examples are low value prints & low value posters for this type of backing. Any art that have sentimental value or a higher monetary value I use 2 ply cotton (rag) mat between the art and the acid free foam core, coroplast, or in some framing I may even mount to 8 ply cotton mat. It is all a matter of what you need for the individual frame job.

Mat board, 4 ply as default.

Foam board, if and when it's an issue, cannot have the same properties throughout as preservation quality mat board. Foam board may be fine as a frame backing but you shouldn't - again, if/when it matters, use the frame backing board as the mounting board as well.

Even with a matboard mount back, it's important to support the back with more. We've had a lot of things come in for reframing that were backed only with matboard, and it warps over time. As Robo mentioned, foam board is a good frame backing.
