Insulation configurations created by low density, loose-fill, particulate, blown insulation and/or fiber batt insulation in combination with high density, loose fill, particulate, blown and/or fiber batt insulation placed under or over the low density insulation, depending upon location. The insulation configurations are designed for, but are not limited to, attic insulation and floor insulation, where low density, loose-fill, particulate, blown and/or fiber batt insulation is normally used. The high density insulation so characterized isolates the low density insulation and greatly reduces air infiltration into, and circulation through, the resulting high and low density insulation configurations. The air infiltration or circulation which the insulation configurations are designed to minimize is generally characterized by, but is not limited to, heat-induced natural convection. A method of installing a high density layer of loose-fill, particulate, blown and/or fiber batt insulation under or over low density, loose-fill, particulate, blown and/or fiber bart insulation, for isolating the low density insulation and creating layered insulation configurations of high efficiency by reducing air infiltration into and through the insulation configurations.
