Modularized insulation, systems, apparatus, and methods

An insulated aircraft component, comprising:

• at least one surface,
• at least one strut partitioning the surface;
• and
• a modular insulation blanket system comprising a modular insulation blanket, the insulation blanket being comprised of a plurality of batting blocks and a cover having sealed perimeter edges, a distal layer and a proximal layer;
• the layers being mated in a sealed relationship along a lattice of longitudinal and latitudinal heat sealed seams, the seams forming a plurality of modules between the layers, the batting blocks being disposed between said layers within the modules which are separated by heat-sealed seams, and the insulation blanket being affixed to the surface of the aircraft component such that at least one of the heat-sealed seams spans across the at least one strut and the strut is sandwiched between adjacent modules.
