Abstract
An insulating glass unit is shown comprising a pair of generally parallel, spaced-apart glass-panes and a spacer peripherally joining the glass panes to each other. The spacer is a tubular structure, and may include a particulate desiccant filling at least a section of the interior and conforming to the interior configuration thereof to contribute compressive strength to the spacer. The spacer desirably is made from stainless steel sheeting having a thickness not greater than about 0.005 inches. In a preferred embodiment, the spacer includes side walls sealed to the glass panes and an outer wall extending between the side walls and having a sealant free portion between the side walls that extends substantially completely about the periphery of the glass unit.
