1. A multilayer film comprising, in order: a) a selectively permeable outer layer comprising a polyamide;b) optionally an intermediate adhesive primer layer;c) a moisture barrier membrane comprising a polyvinylidene chloride nanocomposite, said polyvinylidene chloride nanocomposite comprising an unmodified, non-intercalated, layered nanoclay dispersed in a polyvinylidene chloride polymer;d) a first adhesive tie layer; ande) a fibrous substrate on the first adhesive tie layer. 2. The multilayer film of claim 1, wherein the moisture barrier membrane consists essentially of an unmodified, non-intercalated, layered nanoclay dispersed in a polyvinylidene chloride polymer. 3. The multilayer film of claim 1, wherein the nanoclay content of the moisture barrier membrane is from greater than zero to about 2% by weight of the moisture barrier polymer. 4. The multilayer film of claim 1, wherein the moisture barrier membrane consists of an unmodified, non-intercalated, layered nanoclay dispersed in a polyvinylidene chloride polymer. 5. The multilayer film of claim 1, wherein the moisture barrier membrane has a coating weight of from about 0.05 lb/ream to about 1.2 lb/ream. 6. The multilayer film of claim 1, wherein the moisture barrier membrane has a moisture permeability rate of about 0.5 perm or less at 25% RH and 21° C. as determined by ASTM E96, Procedure A (50% dry cup), and from about 5 perm to about 40 perm at 95% RH and 21° C. as determined by ASTM E96, Procedure B (90% wet cup). 7. The multilayer film of claim 1, wherein the selectively permeable outer layer consists essentially of a biaxially oriented polyamide layer having a thickness of about 15 μm or less. 8. The multilayer film of claim 1, wherein the fibrous substrate comprises a non-woven fabric comprising biodegradable polymeric fibers. 9. The multilayer film of claim 8, wherein the fibrous substrate comprises multiple plies of non-woven fibers that are consolidated with a polymeric matrix material. 10. The multilayer film of claim 1, wherein the optional intermediate adhesive primer layer is present, and wherein the fibrous substrate comprises multiple plies of non-woven fibers that are consolidated with a polymeric matrix material. 11. The multilayer film of claim 1, wherein the amount of nanoclay in the moisture barrier membrane is from greater than zero to about 10% by weight relative to the weight of the moisture barrier polymer, and wherein the selectively permeable outer layer consists of a polyamide. 12. A multilayer article comprising an insulation material attached to the fibrous substrate of claim 1 via a second adhesive tie layer. 13. A multilayer film consisting of, in order: a) a nylon 6 layer;b) optionally, an intermediate adhesive primer layer;c) a polyvinylidene chloride nanocomposite layer, said polyvinylidene chloride nanocomposite consisting of an unmodified, non-intercalated, layered nanoclay dispersed in a polyvinylidene chloride polymer;d) a first adhesive tie layer; ande) a fibrous substrate on the first adhesive tie layer. 14. A method of producing a multilayer film, comprising: a) providing a selectively permeable outer layer comprising a polyamide;b) optionally applying an intermediate adhesive primer layer onto the selectively permeable outer layer;c) applying a moisture barrier membrane onto the selectively permeable outer layer, the moisture barrier membrane comprising a polyvinylidene chloride nanocomposite, said polyvinylidene chloride nanocomposite comprising an unmodified, non-intercalated, layered nanoclay dispersed in a polyvinylidene chloride polymer;d) applying a first adhesive tie layer onto the moisture barrier membrane; ande) applying a fibrous substrate on the first adhesive tie layer. 15. The method of claim 14, further comprising attaching an insulation material to the fibrous substrate via a second adhesive tie layer. 16. The method of claim 14, wherein the nanoclay content of the moisture barrier membrane is from greater than zero to about 2% by weight of the moisture barrier polymer. 17. The method of claim 14, wherein the selectively permeable outer layer comprises a biaxially oriented polyamide layer having a thickness of about 15 μm or less. 18. The method of claim 14, wherein the fibrous substrate comprises a non-woven fabric. 19. The method of claim 14, wherein the moisture barrier membrane has a coating weight of from about 0.05 lb/ream to about 1.2 lb/ream. 20. The method of claim 14, wherein the moisture barrier membrane has a moisture permeability rate of about 0.5 perm or less at 25% RH and 21° C. as determined by ASTM E96, Procedure A (50% dry cup), and from about 5 perm to about 40 perm at 95% RH and 21° C. as determined by ASTM E96, Procedure B (90% wet cup).
