2012 IECC - Slab-on-grade Zone 4B
I will have an ICF stem wall that will transition into the ICF house wall. The interior will be a slab-on-grade design. This is for a Zone 4B (desert) climate.
1 - Should the vapor barrier be on-top or below the rigid EPS?
2 - What thickness is good for a vapor barrier?
3 - Will 3" of rigid EPS suffice for a Zone 4B climate?
4 - Any links to some details showing the above condition?
5 - Should crushed & compacted rock be used below the EPS and concrete slab?
