A wall construction suitable for exterior load bearing walls includes spaced studding positioned vertically between upper and lower plates with the inner surfaces of the studs scalloped so as to present limited areas of contact with lath and plaster or drywall. Insulating board is positioned on the outer continuous surface of the studs with a foam board affixed directly thereto. Siding or the like is positioned on the exterior of the foam board to form the exterior surface of the wall. Insulating bats are positioned within the wall cavity adjacent the insulating board and between the spaced studding. Openings are provided in the interior wall surface to circulate warm air in the interior of the wall cavity. Additional openings are provided in the lower plate of the wall to allow air to circulate from a basement area into the wall cavity. The spaced transversely positioned scallops in the inner surface of the studding substantially isolates the interior wall from the exterior insulating board, foam and exterior siding.
An improvement in an exterior load bearing wall construction having horizontally spaced vertically standing studding and outer and inner wall portions supported thereon, said improvement comprising the formation of said outer wall portion consisting of at least two layers of insulating board and at least one layer of insulating batting and an exterior surfacing material, a plurality of closely spaced scallops formed in the inner surfaces of said studding to form narrow transverse areas therebetween, said inner wall portion comprising dry wall and the like positioned against said narrow transverse portions of said studding, upper and lower plates positioned on the upper and lower ends of said studding, said outer wall portion extending only partially into areas of said wall construction between said studding so as to provide air spaces between said outer wall portion and said inner wall portion and openings in said inner wall portion for ventilating said air spaces.
