A sealed insulating unit includes two parallel opposed panes with a spacing and sealing system between the two panes. The panes and the spacing and sealing system together define a sealed gas space. The spacing and sealing system includes a spacer frame with a primary seal between each side of the spacer frame and the opposing pane face and a secondary seal extending between the panes outside the outer peripheral face of the spacer frame. Each primary seal is greater than 0.4 mm thick on construction of the unit and has at least 7 grams of sealant material on each side of the spacer frame per meter of the spacer frame length. A spacer for a sealed insulating unit has side walls in which are defined elongate recesses, the dimensions of the recesses being selected such that sufficient primary sealant can be accommodated to provide in the sealed insulating unit opposed primary seals each at least 0.4 mm thick.

1. A double sealed insulating unit comprising two parallel opposed panes with a spacing and sealing system therebetween defining, with said panes, a sealed gas space between them, said spacing and sealing system comprising a spacer frame with a primary seal between each side of the spacer frame and the opposing pane face and a secondary seal extending between the panes outside the outer peripheral face of the spacer frame,wherein each primary seal is greater than 0.4 mm thick on construction of the unit and comprises at least 7 grams of sealant material on each side of the spacer frame per meter of the spacer frame length, and wherein the spacer frame comprises an elongate hollow metal member having opposed outer and inner walls connected together by two opposed side walls, each side wall defining therein an elongate recess accommodating at least a part of the sealant material, each recess having an arcuate section having a center of curvature located laterally within the outward lateral edge of a respective side wall.
