A thermally insulating glass panel comprising two spaced-apart sheets of glass enclosing a low pressure space, and interconnected by a peripheral joint of fused solder glass and an array of pillars transversely between the glass sheets. The pillars may be made entirely of metal. Alternatively, the array may be made of a combination of solder glass-containing pillars and non-solder glass-containing pillars. Additional support pieces may be arranged between the glass sheets before the peripheral joint of solder glass is fused.
A thermally insulating glass panel comprising: two spaced apart sheets of glass enclosing a low pressure space and interconnected by a peripheral joint of fused solder glass and an array of pillars; wherein at least some of the pillars are made entirely of metal, and pillar spacing, pillar radius and the number of pillars are chosen such that tensile stress present on outward facing surfaces of the glass sheets is smaller than about 4 MPa, conical stress fracture of the sheets of glass adjacent pillar locations is deterred, and heat flow for the entire p...
