High thermal resistance and permeance insulation material

摘要

A low-emittance material having improved energy efficiency protection against air infiltration and moisture build-up in buildings is disclosed. The aforementioned low-emittance material utilizes existing framing openings or without increasing the wall profile of a building. The present invention provides a low-emittance material which may be implemented on traditional 2×4 framing having R-15 mass insulation material within existing or newly constructed framing cavities. The material of the present invention also meets requirements for serving as a water resistive barrier as defined by ICC AC38.

主权项

1. A flexible insulation for use in an insulation system comprising:
a base insulating material; a substrate material having a first side and a second side; a covering material positioned over the substrate material, wherein the base insulating material provides a system U-value less than 0.063; and a plurality of perforations opening through both the base insulating material and the covering material; wherein the plurality of perforations provide the flexible insulation with a permeance and water vapor transmission of about 5 perm to about 20 perm.
