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.
Claims18
A flexible insulation comprising:
- an insulating material having a thickness between 3/16 and ⅜ inches, the insulating material including a closed cell polyolefin foam;
- a reflective covering material positioned over the insulating material, the insulating material having a side that is directly or indirectly adjoined to the reflective covering material;
- and
- a plurality of punched holes, wherein each of the plurality of punched holes has an initial diameter of at least 1/16 inch and extends completely through at least both the insulating material and the covering material, at least some of the plurality of punched holes having a spacing of about one inch between adjacent ones of the plurality of punched holes, wherein formation of the plurality of punched holes removes material in the form of the punched holes from the flexible insulation.
A method for manufacturing a flexible insulation comprising the steps of:
- providing a first layer and a second layer, the first layer being a first reflective facing layer that reflects radiant heat and the second layer being an insulation layer having a thickness between 3/16 and ⅜ inches, the insulating layer including a closed cell polyolefin foam;
- adjoining at least the first reflective facing layer directly or indirectly with the insulation layer;
- passing the adjoined layers through a drive roll assembly;
- and
- punching a plurality of holes completely through the adjoined layers according to a perforation pattern using a collar mechanism mounted to the drive roll assembly, wherein each of the plurality of punched holes has an initial diameter of at least 1/16 inches, the collar mechanism creating openings through the reflective facing layer, the first polyethylene layer, and the insulation layer, wherein at least some of the plurality of punched holes have a spacing of about one inch between adjacent ones of the plurality of punched holes, and wherein the punching the plurality of holes removes material in the form of the punched holes from the flexible insulation.
