By firring out the siding three eights of an inch over this tyvek commercial housewrap water can never hold against the structure-

It makes it mechanically impossible for water to work its way in

My house was built as a spec house I believe. Its vinyl sided, with aluminum faced foam board "sheathing" and blown in Cellulose to insulate the wall cavity. Then a layer of drywall. I could literally break into the house with a utility knife!

Been wanting to re-side, add OSB sheathing, housewrap and new windows. Its a pricey project though. This is a good tip, if that project ever comes to fruition.
