The invention concerns an insulating part comprising a sealed casing defining an inner enclosure (), the part having thermal conductivity of less than 100 mW/m.K, the sealed casing () comprising at least one thin metal sheet () having a thickness of less than 1 mm and welded peripherally to keep the enclosure under low pressure and/or controlled atmosphere, the weld, which is produced in a chamber under low pressure and/or controlled atmosphere, having a leakage rate of less than 10Pa&#xb7;m/s, after a first thermal treatment according to the standard RTCA-DO 160-G, section 5, Cat A (from &#x2212;55&#xb0; C. to 400&#xb0; C.) and a second thermal treatment at &#x2212;196&#xb0; C. for 1 hour.
