This problem is about to snow ball it has already had a big impact here in NC, the tyvek insulation installation technique has retained the moisture causing mold,(some say).

TYVEK=good

lack of insulation and ventilation is bad.

(I'm in WNC, neighbor.) The housewrap isn't really the problem, it's just poor HVAC system design. Actually, I should say "lack of HVAC system design".

Get yourself a hygrometer ($30), and monitor the relative humidity in your home. Keep it between 40 and 60% if you can.

Until recently, I was working as an electrician on million dollar homes up in the Highlands/Cashiers area. The contractors installed the crappiest, cheapest systems in those homes that I had ever seen. The rich saps paying for those fancy lake homes will be uncomfortable forever in them.

I saw one unit that was installed in an almost-inaccessible attic space above a bedroom. There was just no way that anybody was ever going to get up there and clean the coils or change the filter.
