  • Roll-up thermal insulator
    Patent number: 5678622
    Abstract: A roll-up heat insulation device in the form of a planar structure which, in the unrolled state, forms a multichamber system for providing air-filled, preferably circulation-free, compartments where volume can be reduced again when being rolled up. The planar structure is constructed in the form of a heat insulating mat which possesses at least two consecutively disposed foils, where reciprocal distance is controllable with the aid of distance webs that are offset in the vertical distance (AV) and are flexibly joined to adjacent foils.
