The present invention pertains to an insulation system comprising one or more insulation blankets, wherein each of said multilayer insulation blankets comprises: —a core consisting of an insulation material [material (I)], and —a shell encapsulating said core, said shell comprising at least one multilayer assembly comprising: (1) an outer layer [layer (L1)] consisting of a composition [composition (C1)] comprising, preferably consisting of, at least one thermoplastic polymer [polymer (1)] having a limiting oxygen index (LOI) of at least 20% by volume, wherein at least one surface, preferably the inner surface, of said layer (L1) comprises one or more grafted functional groups [surface (L1-f)], (2) directly adhered to said at least one surface (L1-f), a layer consisting of at least one metal compound (M1) [layer (L2)], and (3) optionally, directly adhered to the opposite side of the layer (L2), a layer consisting of at least one metal compound (M2) [layer (L3)], said metal compound (M2) being equal to or different from said metal compound (M1). The present invention also pertains to a process for the manufacture of said insulation system and to uses of said insulation system in various applications including aircraft applications.
