A pass-by insulating glass window unit for replacing single glazing including a sealing assembly sandwiched by glazings having dissimilar plane surface dimensions. One glazing, the exterior glazing, has the plane dimensions of the single glazing it replaces. The other, the interior glazing, and the sealing assembly have plane dimensions slightly smaller than the dimensions of the window opening. The pass-by insulating glass window unit is assembled with each of the four edges of the exterior glazing extending equidistantly outwardly from the aligned edges of the sealing assembly and the interior glazing. The thickness of the sealing assembly is predetermined to provide an enclosed insulating space of optimum insulating value. For use in double hung window sashes, the thickness is chosen to assure passage of the movable window openings, and to position the interior glazing to be in approximate alignment with the plane of the interior surface of the wood sash. The assembled pass-by insulating glass window unit is placed, interior glazing first, through the window opening or sash from the exterior side until the exterior glazing contacts the glazing rabbet.
