I'm trying to decide between flash and fill (BIB) and all open cell foam for exterior walls. #construction #green
Hi, I live in MD in climate zone 4 below Baltimore, but almost 5. We are building a house with 2x6 walls 16" OC all brick exterior. I have an estimate for 1 inch closed cell then blown in fiberglass fill and a quote for all open cell foam. The all open cell is 30% more, should I be worried about condensation in walls and go with the all open cell foam or will I be safe in this climate zone with the flash and fill. My neighbor did the flash and fill however only on 1 wall not all without any issues. I need to decide soon and am confused on which way to go.
