I will begin siding my house with vinyl soon and would like some opinions on whether to lay down 1/4 inch fanfold or not. Only reason I would do it is for the extra insulation but from what I gather the r-value of the stuff is only 1 or 1.5 . I will be wrapping house with Tyvek. The exterior area of the house is abt 2000 sq feet.
Is this a waste of money?
Thanks in advance
