   Thanks, Gabe, that's just what I was looking for. Nice to know I remembered correctly.

   I've seen that stuff somewhere.  Wondered where you'd get lath straight enough to match the grooves!

   nick.. we've been insulating our crawl spaces and basements with Performguard EPS. (3" ) with 1/2" OSB.. the Performguard is treated with borates.. about R20... paying about $45 for a 4x8..

   the only thing left to insulate is the 12x12 space on top of the foundation which we do by drilling thru the subfloor above and blowing cells in thru a 1" nozzle..Mike Smith   Rhode Island : Design / Build / Repair / Restore

   Looks interesting. Are you getting it from an SIP manufacturer or a local place? And how are you attaching it to the basement walls?

   This is going to be a full basement under an addition we're about to start building. It will be radiant slab with 2" styrene under, and 12" block walls with 40 mil self-adhesive bituthene waterproofing. Eventually it will be a spare bedroom, so we are going to insulate and drywall it, and that's it. I'm still grappling with the problem of having two vapor barriers. I'm not worried about water, between slab drains, footer drains, bituthene, and gravel backfill water shouldn't be a problem, but I don't want to trap any moisture between the bituthene and the interior foam. Fiberglass is out of the question, and I suppose I could wet spray cells, but I think that might be a little bit overkill.

   all of our foam comes from Branch River Foam.. which i learned about here two years ago...most of the EPS guys are associated with  R-control, as is Branch River .. some kind of franchise or licensing parent...

   they can bond blueboard, cement board, osb.. or anything else you might want..

   the floor system above locks in the top and the concrete slab locks in the bottom.. in this case we only have about 8'2 from the sub-slab to the bottom of the subfloor above.. in a normal basement we could order 9' high panels and do the same thing..

   or use the 8' high panels and block the top differrently..

   here's the same job with a 3" panel and blueboard helping us make the transition from the cathedral ceiling area to the area above the old attic...

   forgot the link for R-Control..

   BTW, my local Lowes store has R-control sheets in 1/2 and 2" if I remember correctly.
