OSB versus Styrofoam
I live in climate 3 in warm humid Louisiana and will be building in the next six months. Most of the builders in the area use OSB in the corners and 1/2 styrofoam over the rest of the home for sheathing. I understand the styrofoam has much better insulating value than OSB but I also don’t want a home that is structurally weak in a wind storm. Any advice on this?
