Do we need housewrap?
Building a new home in Hanover NH. Advantech sheathing will be taped. Then 2 1/2 inches of XPS will then be applied and taped. Then firing strips, then Hardy siding.
Initial plan was to place house wrap on outside of of XPS. Our builder says that perhaps house wrap is not necessary, given the tape on sheathing then again on XPS, but he is willing to add it if we prefer.
Is there any advantage to house wrap with this construction method?
