My whole house has been sheathed with OSB. My builder will be applying housewrap to this next week. I will have "innie" type windows installed as well. He will also be covering the housewrap and OSB with a layer of foam board. Since the housewrap is under the foam, is it necessary that he tape all foamboard seams? I would assume since the housewrap is under the foam, this would not be necessary?
