Abstract
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.

1-25. (canceled)
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 thermal resistance;
- 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 over 5 perm.
A high reflectance insulating material comprising:
- a base insulating material, wherein the base insulating material comprises closed cell polyethylene foam or polyolefin providing thermal resistance;
- a strengthening layer on the base insulating material;
- a covering material positioned on the support material, the covering material including a reflective facing, the strengthening layer reinforcing the covering material;
- a plurality of perforations, wherein each of the perforations comprises an opening through both the base insulating material and the covering material;
- and
- wherein the plurality of perforations provide the insulating material with a permeance and water vapor transmission over 5 perm.
A method of fabricating a high thermal resistance and high permeance insulation material comprising:
- providing a base insulating material;
- applying a strengthening layer having a first side and a second side on the base insulating material;
- applying a covering material positioned over the second side of the strengthening layer, wherein the base insulating material provides thermal resistance;
- and
- creating a plurality of perforations opening through both the base insulating material and the covering material sufficient to provide the insulation material with a permeance and water vapor transmission over 5 perm.
A flexible insulation, comprising:
- a base insulating material having a nominal thickness that does not exceed ¼ inch and providing thermal resistance;
- a substrate material having a first side and a second side;
- a covering material positioned over the substrate material;
- and
- a plurality of perforations opening through both the base insulating material and the covering material,
- the perforations being arranged in a perforation pattern in the flexible insulation to allow water vapor to be transmitted through the perforations, the perforation pattern eliminating the possibility of the perforations resealing once formed in the flexible insulation, the flexible insulation achieving an emittance of 0.10 or less.
