Abstract
The present disclosure relates generally to an insulation-retaining sheet, e.g., for blown-in insulation, that includes an integral vapor-retarding membrane. In one aspect, the disclosure provides an insulation-retaining sheet including a sheet of mesh having an air permeability of at least 200 cfm per square foot; and one or more strips of vapor-retarding membrane, the one or more strips of vapor-retarding membrane being laminated to the sheet of mesh, the first side edge each of the strips of vapor-retarding membrane extending to the first side edge of the sheet of mesh, the second side edge each of the strips of vapor-retarding membrane extending to the second side edge of the sheet of mesh, wherein the insulation-retaining sheet has a plurality of open zones extending laterally from the first side edge of the sheet of mesh to the second side edge of the sheet of mesh in which no vapor-retarding membrane is laminated to the mesh.
