I assume you mean Tyvek housewrap.
Tyvek is used as a vapor barrier to keep water and moisture from penetrating walls of a structure. It also helps prevent drafts but at the same time allows the house or structure to breathe.
Tyvek is put on walls during construction after the sheathing. This could be plywood or a foam sheathing. It also helps keep the structure or house dry until the exterior finish is applied.
