An encapsulated insulation composite system for increasing the burn through resistance of an aircraft fuselage includes: an insulation layer of glass fiber or foam insulation and a coating or interleaf barrier layer of a high temperature resistant material and/or a coating or barrier layer of a high temperature resistant material on an outer major surface of the insulation layer of the composite and a film encapsulating the composite. Preferably, the barrier layer or layers include a reflective mineral, such as a reflective mineral containing coating carried on a sheet material. Preferably, the encapsulating film is a polymeric film such as a polyimide film.

[ What is claimed is:] [1.]1. An insulation system for increasing the burn through resistance of an aircraft fuselage having an outer skin, comprising:an encapsulated multilayered insulation composite; the multilayered insulation composite including a first insulation layer, a second insulation layer, and a first interleaf barrier layer of a high temperature resistant reflective mineral material; the insulation layers each being glass fiber insulation layers having a thickness of about one inch and having a density between about 0.34 pcf and about 0.42 pcf; the insulation layers and the interleaf layer each having major surfaces extending in planes substantially parallel to each other and being enclosed within a polyimide film; and the multilayered insulation composite having a burn through time of at least five minutes.
