We used Performwall and it is holding up nicely.A few other houses that used CMU block with a outside sheathing of thin insulation then stuccoed have had big mold problems.The earthquake also really effected homes that used CMUs on the Parapets...they vibrated at a slightly different rate and cracking occurred...followed by rain then mold....people fix stuff like this then hide it and who would know....until the next event or mold comes back.
