ABSTRACT:
A vacuum thermal insulation comprises an inflatable load-carrying structure and gas impermeable envelope with proper gates for inserting pressurized air into the structure and an evacuating vacuum chamber wherein, pressurized air is used for inflating and stiffening the load-carrying structure in order to prevent scrunching the envelope due to the atmospheric pressure. Thereby, producing vacuum in locations which are out of structure.
