Zip system has many issues, I wouldn't install it. It basically is plastic paint on plywood

Tyvek is still fairly common in this area...for the most part the extra insulation within the panelized systems is overkill.

As for how pretty it is, it doesn't need to be ironed flat. Air moves through is just fine, that's the point of a house wrap. It really is just a moisture barrier.

As a builder, I prefer my moisture barrier to be separate from the sheathing, even when I am using rigid foam paneling. I will use tyvek even with a panelized house wrap - it is cheap and effective.

it's all zip system now

it doesn;t matter. most contractors have stopped using it anyway because you can get sheets of plywood that have the same treament. it is green sheets you se eon sides of construction.

or you can get an iron and go make it all pretty. It annoys me when it is upside down

I've been passing an addition project in our neighborhood, and have noticed that the Tyvek doesn't seem to be placed perfectly flush with the walls -- there seem to be a good number of wrinkles, air bubbles, etc.

Just wondering if this is normal? I've been considering asking the owner of the house if they would recommend their contractors, but have been wondering about the Tyvek...
