I am in the process of moving an old 30x40' barn to my site, and converting it into a home. I would like to use "Curtain Wall Stress Insulated Panels" (OSB, foam, drywall from the Winter Panel Co.) for all the exterior walls. What is the best method for supporting these panels? Do I need to support them with an extra wide foundation wall ($$$), or can I use some sort of support which extends out from beneath the sill, or do these panels even need to be supported from the bottom?
