ABSTRACT:
A vacuum-insulated thin-wall panel requires internal spacers to resist the compressive force of the atmosphere and to hold the sides apart. Such spacers are paths for heat flow by conduction. However, in the panel of this invention, the sides are held apart by a web of relatively thin and long spacers stressed in pure tension. Heat flow through such spacers is substantially less than through the more massive spacers designed to be stressed in compression.
