Abstract: A multilayer insulation with an array of posts is provided. In particular, the posts are comprised of multiple post or support elements that are interconnected to radiation shields or sheets comprising the layers of the integrated multi-layer insulation (IMLI) structure. The support elements maintain spacing between adjacent sheets, thus maintaining a volume between the sheets. The support elements can each feature a plurality of support arms. The support elements can each additionally include a support beam that defines a minimum spacing between sheets when the IMLI structure is under a compressive load. Neighboring support elements can be interconnected to one another by beams.
