Open Cell Spray Foam - crawl space and interior walls

I was thinking of something I believe they call duo rock board. It is about 3/4 inch thick concrete with mesh in it to hold it together. It is often used under tile applications but I was thinking it may be a good choice. I would do more research into what is best product but if you decide to encapsulate you want something that looks ok on the exterior and that will allow you to spray and hold the foam on the inside. If these were put inside of the slats I think you could keep the current look on the outside. I will be heading up mid week and will take some pics and post them or PM me and you are welcome to come by and take a look. It was not cheap but it was worth it. About $5000 for a 1600 sq ft footprint if i remember right.
