This insulating building panel encloses a vacuum between two parallel plates that are separated at their edges by a post frame. Within the vacuum chamber, a support structure prevents implosion of the panel due to suction pressure. Glass plated vacuum panels form windows and steel plated panels cover other exterior surfaces, but materials. used are not restricted to those mentioned. When vacuum is applied, the plates engage the past frame in an airtight manner with no other means of attachment between them except at an anchor point in each steel plated panel where plates are held to their post frames in order to maintain their relative positions to each other. When the weather exposed plane of a steel plated panel expands or contracts away from the anchor point in relation to the post frame due to fluctuating outside temperatures, the plate slides laterally over the post frame without obstruction and without forcing an accompanying movement of the post frame. Warping, which would otherwise render the panel impractical, is thereby eliminated. Stress upon support structures in steel plated panels due to thermally induced movement of weather exposed plates is also eliminated, spacers between plates being spheres that roll with such movement.
