i was wondering which product was better, Dow Weathermate or Tyvek house wrap? I live in NY and have a uninsulated 1950 block/stucco house with high humidity levels inside, predominately during the winter with condensation on windows and mildew in a few spots on outside walls if furniture is up against the wall . We are planning to have the house vinyl sided. They will be putting foam insulation on over the existing stucco then wrapping the house in Weathermate housewrap.
Tyvek has a much higher Permeance rating than the Weathermate. Because of the moisture in the house would it be better to go with a wrap that has a higher rating?
Thanks
