EPS, XPS, or polyiso, which board?
EPS is cheapest and vapor-permeable; good for exterior walls and below grade. XPS has higher R per inch and resists moisture; common on roofs and under slabs. Polyiso has the highest R per inch but loses some R in cold weather, fine in San Diego where it rarely gets that cold. The pro picks based on assembly and budget.
