Slab Insulation Protection (Cement Board?)
Building a monolithic, slab-on-grade foundation with 2″ of rigid foam (XPS) around the perimeter. In a video on the “Eco Home Network” channel, they use cement board to protect the XPS that would otherwise be exposed on the outside of the slab.
I am wondering if anyone has experience with cement board for this use case and any thoughts on durability and getting a good finish on the cement board.
