Thermal insulation retaining sheet with integral vapor retardation membrane

摘要

The present disclosure generally relates to a thermal insulation holding sheet, for example, for blown insulation comprising an integral vapor retardation membrane. In one aspect, the present disclosure provides a mesh sheet having air permeability of at least 200 cfm/ft ² ; And a strip of at least one vapor retardation membrane, wherein the strip of at least one vapor retardation membrane is laminated to a mesh sheet, and the first side edge of each of the vapor retardation membrane strips is a first side edge of the mesh sheet. And the second side edge of each of the vapor retardation membrane strips extends to the second side edge of the mesh sheet, and the heat-retaining sheet extends sideways from the first side edge of the mesh sheet to the second side edge of the mesh sheet. It has a plurality of open zones, where the vapor retarding membrane is not deposited on the mesh.
