An insulation blanket is disclosed that contains fire-blocking materials for preventing rapid penetration of fire into an aircraft fuselage in case of a fire outside the aircraft. The insulation blanket contains at least one layer of fiberglass or other thermal-acoustic insulation material without fire-blocking properties, and one or more layers of fire-blocking material. The fire blocking material is wider than the thermal-acoustic insulation so that it may be folded against and attached to adjacent structural frame members of the fuselage. In the alternative, a thermal-acoustic insulation material is used that has fire-blocking properties instead of the separate layers of fire-blocking and thermal-acoustic insulation materials. A method for installing insulation blankets according to the present invention is disclosed, whereby a fire-blocking insulation portion of the blanket is folded against and attached to frame members of the aircraft using attachment posts or spring clips.

1. An insulation blanket, having two long edges, for installation between parallel structural frame members spaced a distance apart, said insulation blanket comprising lofted insulation adjacent to fire blocking material, wherein said lofted insulation has a width substantially equal to said distance between said parallel structural frame members, and said fire blocking material has a width sufficiently greater than said distance between said parallel structural frame members and extends beyond the width of said lofted insulation along at least said two long edges so that said fire blocking material may be folded against and attached to each of said parallel structural frame members when said insulation is placed between said parallel structural frame members.
