A wall assembly comprising exterior and interior severally insulated wall sections combined to present a jointly insulated wall. A continuous sheath of cured foam insulates the exterior wall section and isolates the bracing studs therein from those of the interior wall section. The latter section is insulated with conventional fiberglass batts and is laterally adjacent the first wall section resulting in a jointly insulated common wall assembly impervious to air infiltration and highly resistant to thermal flow therethrough.

An exterior wall assembly comprising: a first row of longitudinally spaced apart studs each stud presenting an inner and outer nailing face with a pair of web faces extending therebetween; a second row of longitudinally spaced apart studs each stud presenting an inner and outer nailing face with a pair of web faces extending therebetween, said second row of studs being longitudinally and laterally offset from said first row of studs, said lateral offset of each stud of said second row of studs extending a selected nailing face of at least one stud of said second row of studs into the area between adjacent studs of said first row of studs; means for maintaining said first and second row of studs in a generally vertical relationship; first sheathing means affixed to said outer nailing faces of said first row of studs, said first sheathing means having an inner surface cooperating with the opposing web faces of adjacent studs of said first row of studs to form a series of first side-by-side stud cavities having at least a nailing face of said at least one stud of said second row of studs protruding therein; a first insulating material spray-applied on the exposed faces of each stud of said first row of studs and along said inner surface of said sheathing means to present, upon curing, a generally rigid serpentine sheet of said first insulating material in said first stud cavities, said insulating sheet continuously extending between said first cavities whereby to position each stud of said first row of studs between said insulating sheet and said sheathing means, said sheet further contacting said protruding face of said at least one stud of said second row of studs and cooperating with the opposing web faces of adjacent studs of said second row of studs to present a series of second side-by-side stud cavities adjacent said first insulated stud cavities; and a relatively flexible second insulating material positioned in said second stud cavities, said second insulating material extending between said adjacent studs of said second row of studs and contiguous to said sheet to present a series of contiguously adjacent and longitudinally offset first and second insulated stud cavities precluding air infiltration through said cavities and the appearance of air spaces therebetween whereby to present an exterior wall assembly highly resistive to thermal flow therethrough.
