There are ways to improve this system or others like it by taping the seams on the weather barrier "rain plane"(tyvec), caulking around penetrations in the weather barrier such as vents, electrical,etc. I would also suggest ridgid insulation (2" styro) behind the weather barrier that has taped seams. This will help control thermal, vapor, and air issues. So I agree that the more continuous your barriers are the better it will be, but I streess that no wall is wet Proof. Get the water out ASAP!

Thanks for the comment and good point, however, No wall is completely weather proof weather that is CMU, vinyl, hardie, etc, as the exterior cladding material is 'only' for decorative reasons. Yes it does block out most of the rain/snow but every wall cavity will get wet. It is the time that the cavity is wet determines if you will have problems. Creating the air space behind the cladding to create air movement and a place for water and vapor to escape is the biggest key.

With a full vented cavity behind the siding material wouldn't a failure of the underlying wrap say a nail puncture or tear become a severe water intrusion point since the siding has a full vent at the top and bottom? I'm thinking a moderate rainstorm with blowing rain.
