摘要： 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.

摘要： The present disclosure relates generally to vapor retarding building materials and methods for making them. The present inventors have found simple and cost-efficient materials that have low water vapor permeability at low relative humidities and that can be provided as a coating on a building material substrate. Notably, in many embodiments, the materials can have high water vapor permeability at high relative humidities. In one embodiment, the disclosure provides vapor retarding articles comprising a building material substrate; and a polymeric coating layer coated on the building material substrate, the polymeric coating layer comprising an inorganic hydrophilic particulate filler dispersed in a continuous organic phase comprising a hydrophobic polymer, wherein the content of the filler is from about 30% to about 85% by weight of the polymeric coating layer, the vapor retarding article configured to have a water vapor permeance of no more than about 1 Perm at 25% relative humidity.
