A thermally insulating jacket under reversible vacuum, having an inner wall, an outer wall and an hollow space between these walls. The hollow space is in fluid communication with an outer housing containing a reversible non-evaporable hydrogen getter loaded with hydrogen. The reversible hydrogen getter has a certain hydrogen equilibrium pressure. The hollow space contains a non-evaporable promoter getter having a certain hydrogen equilibrium pressure. These jackets can be employed with heat accumulators, batteries, cryogenic vessels, cryogenic pipes, catalytic silencers and solar panels.
