Abstract
A method of forming a building wall system in the absence of building paper or housewrap that comprises providing a generally flat structural insulating sheathing. The sheathing comprises at least a first layer, a second layer and a third layer. The first and third layers comprises an alkenyl aromatic polymer foam. The second layer comprises paperboard. The insulating sheathing is fastened to the stud wall to form the building wall system such that a seal is formed that inhibits water from penetrating therethrough. The building wall system in the absence of building paper or housewrap passes the test requirements set forth in Section 1403.2 of the 2003 International Building Code.
