If I'm putting up vented aluminum soffits on an older house where there was enclosed wood soffits, should I be using tyvek house wrap on the outside walls, at least where I can get at it with the eaves opened up for the new soffits. The current siding is painted wood over some tongue and groove type boards. In the future I would like to pull the siding off and put up vinyl. I suppose the more I can do to insulate the house the better, right?
