THERMAL INSULATING MATERIAL

摘要

A thermal insulating material that is superior to blown-in polyurethane foam that has vertical insulating properties and lateral thermal conducting properties, and is made of alternating layers of aluminum metal foil and insulating foam that causes the temperature of a cold spot to increase at least 3 degrees F. when compared to an equivalent amount of blown-in polyurethane foam. This material is suitable for increasing the temperature of cold spots of the exterior of refrigerator/freezer doors.

主权项

1. A thermal insulating material comprising alternating layers of aluminum foil and insulating foam material,
wherein the material is less than about ½ inch thick; wherein the material has vertical thermal insulating properties, wherein the material has lateral thermal conducting properties; wherein the material is applied to a chamber formed by an exterior panel and an interior panel of a refrigerator or freezer door; wherein the exterior panel has an exterior recess which causes a narrowing of the chamber and a cold spot at the exterior recess; wherein the material is applied to the chamber behind the recess; and wherein the material causes the cold spot to increase in temperature by at least 3 degrees when compared to the cold spot insulated with an equivalent thickness of blown-in polyurethane.
