Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
An insulated outer wall construction for a building, said wall construction comprising a structural outer wall, a plurality of elongated rectangular fibrous glass insulation boards mounted, with longer edges extending vertically, in covering relationship to said outer wall on a side thereof facing outwardly of the building, each of said boards being devoid of a vapor barrier and having a scrim adhesively secured thereto on an outer side thereof, the scrim including a flap along one vertical edge of the board overlapping a joint between the board and an adjacent board, fastening means mechanically securing said boards and scrim to said outer wall, and a coat of cementitious material covering said boards, scrim, and fastening means.
Claim 2
Dependent Claim
