A laser sealed evacuated window panel is comprised of two glass panes held spaced apart in relation to each other by a plurality of spherical glass beads and glass welded around the edges to provide an evacuated space between the glass panes that is completely glass sealed from the exterior. The glass welded edge seal is obtained by welding the edges of the glass panes together with a laser beam while the glass panes and bead spacers are positioned in a vacuum furnace and heated to the annealing point of the glass to avoid stress fracture in the area of ...
A thermal resistant panel comprising two panes of glass positioned closely spaced apart in substantially parallel relation to each other, a plurality of spherical glass bead spacers positioned between said two panes of glass to maintain the spacing while minimizing the thermal conduction between said panes, and a continuous glass joint around the periphery of said panel sealing the edges of said two panes together.
