ABSTRACT:
An elongate tubular spacer frame bar for insulating windows. The spacer frame bar is formed of metal and has spaced, staggered sequences of longitudinally oriented elongate slits which increase the length of the thermal conductivity path from the first pane to the second. These slits are formed by displacing the material so that this breaks and shears away along the edges of the slit, thereby forming an effective but narrow air gap. The air gap is sized to prevent the escape particulate desiccant material from within the interior of the spacer.
