Abstract
An insulating glass unit comprising a pair of generally parallel, spaced apart glass panes and a spacer-sealant assembly peripherally joining the glass panes to one another and defining with the glass panes a gas-containing interpane space. The spacer comprises a first web whose edges are joined to confronting surfaces of the glass panes by primary sealant strips, the first web and sealant providing a barrier having a permeance to air and interpane gas of not greater than about 0.06 cubic inches/year-inch-arm, and providing a first thermal path having a thermal resistance of not less than about 8 hr-.degree.F.-ft/Btu. The unit is free from peripheral structure providing a separate parallel thermal path having a thermal resistance less than about two and one-half times that of the first thermal path.
