Tape House Wrap or Exterior Foam
I’m planning to install new vinyl siding on my house with 1” xps foam insulation in climate zone 5 with 2×4 walls. The build up will be plywood, house wrap, 1”foam, and vinyl siding (with no air gap).
in this situation, should my air barrier be foam with taped seams or house wrap with taped seams?
