As most of you guys know, part of our first shipment was material that didn't meet our "perfectly flat, consistent thickness" criteria. It was a "growing pain" sort of situation with the manufacturer learning how to process to our requirements, and we think we have it sorted out. However we do have some stock and after some internal deliberation, reviews of some sheets by local builders, and some kits cut as test cases, we are listing it on the website. Click on "limited offer" page in the header.
The consensus is that this is "about" the same as typical fanfold as far as waves and thickness variation. Some folks say better, but that may be just because it's still pure white, unskinned, unperfed and not printed all over
We're still reworking boxes, so if there is a rush, we may have a bit of delay while we prep for shipment. Shouldn't be more than a few days, though.
