ABSTRACT:
Thermal insulating apparatus for an aircraft fuselage of the type utilizing a sandwich panel construction. A foam insulation panel is provided which includes a plurality of standoffs for contacting the inwardly-facing skin of the sandwich panel. The standoffs may be arranged in a grid pattern, molded integrally with the rest of the panel, and bonded to the skin of the sandwich panel. The insulation panel may be used with or without a trim panel between it and the fuselage compartment, and in either case a sheet of metal foil may be attached to the inside face of the insulation panel. The foam may be of the self-skinning type so as to resist penetration of moisture into the foam panel and help direct condensate away from the fuselage compartment.
