What's the best material (considering price as I'm paying for it) to use for a conservation filler board?

Question Filler Board Suggestion For 1st Conservation Project

If you are talking about hinged paper art on a rag mount board..... I use either AF foam board or poly fluted board.

Second that.

When it's a full conservation job, like a piece of valuable art or a 400-year old map, I use matboard as the filler. Better not to take a chance on the effects of the foam, no matter what the surface material is.
Paul, I'd guess that you then back that mat with something
like Alpharag Artcare or an 8 ply rag board? Matboard alone
would eventually warp. Just asking for the sake of clarification.

How much preservation do you want? And are we talking about the board to which the artwork will be hinged, or the board behind that to add support and fill the frame depth?
AF foam board works nicely, although there is still some lingering question about its stability.
Fluted polypropylene, aka Coroplast, works beautifully with no worries.
For maximum preservation I would use matboard, either 8- or 4-ply or in combination to fill out the back of the frame. By supporting the dust cover it helps avoid punctures in the dust cover and its thermal mass slows fluctuations in the frame's microclimate.

As a FILLER board, (meaning no direct contact with the art - used to "pack out" the back of a frame to back of rabbet) -
In this circumstance, how is rag any more protective (or how is fluted poly any less protective?)
Sometimes I think we just get silly with this "maximum protection" thing.
Wouldn't poly provide better moisture resistance?
And, are we in business to make money? Isn't poly less expensive? Won't it do as good (or from my position a BETTER job) as a filler board?
A. Resistance to warpage (and by alternating flutes much stronger.)
B. Resistance to insects
C. Cost benefit
D. Prove to me that Poly offers less protection than rag board (as a filler board)
E. Why wouldn't archival corrugated also be an acceptable filler material? Aside from the lack of moisture resistance, it offers all the protection one would need.

This is my first conservation project. Please be gentle!
Slightly more info here, as I have one more piece that is in the same situation.
The art was purchased on what appears to be about 1 ply paper.
This paper is slightly buckled at the edges.
I used Jap. paper to hinge at the top, and this is applied to a rag back board. The 2 mat layers are both rag boards.
I was hoping that once assembled, the buckles would press out. They did slightly, but not enough.
I placed no material, aka filler board, behind the rag to where the art is attached. I ran out of rag material!
I'm looking for a filler board to maybe help with the buckles.

No backing board or filler is going to help with the wrinkles. They are part of the art.
I am assuming you are trying to get more pressure to push the art into the mats more in an attempt to flatten??

Mike, it would be interesting to see a picture of the
project. I do think that just having a layer of matboard
behind it isn't enough for the long run. Unless it's eight
ply, a matboard layer with nothing else behind it will
eventually warp in some way.
Good for you for wanting to learn better preservation
techniques. I've learned quite a bit from the Grumble in
this way that has really helped me as a framer.
