Claims
- 1. An insulation configuration for attic floors comprising a layer of non-solid insulation material adjacent said attic floor and at least one moisture vapor-permeable film means positioned horizontally over said insulation material and exposed to the air, whereby air circulation into said insulation material from the attic is reduced.
- 2. The insulation configuration of claim 1 wherein said insulation material is particulate insulation.
- 3. The insulation configuration of claim 1 wherein said film means is a plastic film.
- 4. The insulation configuration of claim 1 wherein said film means is an outer film defining a first boundary of said insulation material and further comprising an inner film horizontally spaced from said outer film, said inner film defining a second boundary of said insulation material, with said insulating material located between said outer film and said inner film, said outer film and said inner film reducing air circulation within said insulating material.
- 5. The insulation configuration of claim 4 further comprising at least one intermediate film horizontally disposed in said insulating material between said outer film and said inner film, said intermediate film spaced from said outer film and said inner film, with a first quantity of said insulating material located between said outer film and said intermediate film and a second quantity of said insulating material located between said intermediate film and said inner film.
- 6. The insulation configuration of claim 1 wherein:
- (a) said insulation material further comprises particulate insulation; and
- (b) said film means is an outer film defining a first boundary of said particulate insulation and further comprising an inner film horizontally spaced from said outer film, said inner film defining a second boundary of said particulate insulation, with said particulate insulation located between said outer film and said inner film, said outer film and said inner film reducing air circulation within said particulate insulation.
- 7. The insulation configuration of claim 1 wherein said insulation material is fibrous insulation.
- 8. The insulation configuration of claim 7 wherein said film means is an outer film defining a first boundary of said fibrous insulation and further comprising an inner film horizontally spaced from said outer film, said inner film defining a second boundary of said fibrous insulation, with said fibrous insulation located between said outer film and said inner film, said outer film and said inner film reducing air circulation within said fibrous insulation.
- 9. The insulation configuration of claim 8 further comprising at least one intermediate film horizontally disposed in said fibrous insulation between said outer film and said inner film in spaced relationship, with a first quantity of said fibrous insulation located between said outer film and said intermediate film and a second quantity of said fibrous insulation located between said intermediate film and said inner film.
- 10. An insulation configuration for floors in structures comprising a layer of insulating material located adjacent the underside of the floor and at least one moisture vapor-permeable film means positioned horizontally under said insulating material and exposed to the air, whereby circulation of air into said insulating material from the airspace beneath the floor is reduced.
- 11. The insulation configuration of claim 10 wherein said at least one film means is an outer film defining a first boundary of said insulation material and further comprising an inner film horizontally spaced from said outer film, said inner film defining a second boundary of said insulation material, with a layer of insulating material located between said outer film and said inner film, said outer film and said inner film reducing air circulation within said insulating material.
- 12. The insulating configuration of claim 11 further comprising at least one intermediate film horizontally disposed in said insulating material between said outer film and said inner film in spaced relationship, with a first quantity of said insulating material located between said outer film and said intermediate film and a second quantity of said insulating material located between said intermediate film and said inner film.
- 13. The insulating configuration of claim 10 wherein said insulating material is fibrous insulation.
- 14. A method for increasing the efficiency of a non-solid insulation layer adjacent the floor of an attic comprising installing at least one sheet of moisture-vapor permeable film horizontally over said insulation layer and exposed to the air in the attic, to reduce air circulation into said insulation.
- 15. A method for increasing the efficiency of non-solid insulation layer adjacent the underside of the floor of a structure comprising installing at least one sheet of moisture-vapor permeable film horizontally under said insulation layer and exposed to the air beneath the floor, to reduce air circulation into said insulation from the airspace beneath the floor.
