Corrugated isn't dimensionally stable enough for anything big. I don't like its ability to attract humidity either. Corrugated styrene is cheap and abundant - a bit too flexible, but better than acid-free corrugated cardboard in that respect.
Hi Bob,
I still have a large supply of Light Impressions Archival Corrugated, similar to or the same as what was linked to above from years ago. Light Impressions, as you know, has undergone a lot of changes since I purchased my stash. I was hesitant to order any more from them, but you might give them a try; maybe they are more reliable now. I used to like their products a lot, especially the interleaving papers.
Anyway, lately I've been ordering corrugated in sizes I don't have lots of from other sources; B&H, university products, etc. A simple search for "archival corrugated" should get you lots of sources; even maybe some in Canada
Drew,
You can get archival corrugated in double-wall as well as single, which is fairly stiff. FWIW I've used single wall 1/8" thick corrugated for frames up to 22x28 with good results. As for moisture; it shouldn't be any more absorbent or moisture retentive than cotton rag board. I've never had any problems with it in that regard. I don't think mounted photos should be displayed in really humid environments, period, but if it can't be avoided, I would think a completely sealed framing option with desiccant of some sort might be in order.
Best,
Doremus
An impervious support mount on the back can be quite important. Museum board, cardboard, etc is quite hydroscopic. A nightmare scenario is either a tropical environment, or a commercial wall space which is poorly insulated, and subjected to serious day/night temp fluctuations. I have run decades of real-world tests with all kinds of substrates in various climates. I won't even use Crescent museum board because it's too hydroscopic. The old Light Impression product was decent, Strathmore too. Rising is the best, which seems to be the same brand Archival Methods is selling in cut sizes. But I demand vapor and condensation resistant backing behind the museum board itself. For the same reason I avoid true glass in front. Acrylic is a much better thermal insulator.
Note, by "backing" I don't mean what the print itself is mounted to, but the additional stiffener and protective layer behind the mats and glazing, involved in a complete framing sandwich.
I have actually done true hermetic encapsulation of big photos. It was involved and expensive. My own method was proprietary. The last one I did was a relatively small piece, but they intended to put it on a wall next to their sauna! I lost track after 20 years, but it was still holding up well to the steam.
