In the manufacture of an insulating unit, a spacer frame having a pair of outer legs and a base connected to provide a U-shaped cross section has one of the pair of legs adhered to marginal edges of a major surface of a first glass sheet by a layer of a moisture-impervious sealant. An elongated side of the spacer frame adhered to the glass sheets moves out of alignment i.e. the plane containing the base of the spacer frame and the plane containing the major surface of the first sheet are not perpendicular to one another. Magnetic forces are applied to the base to maintain the elongated side of the spacer frame in alignment i.e. the plane containing the base of the spacer frame is perpendicular to the plane containing the major surface of the first glass. Thereafter, a second glass sheet is adhered to the other outer leg of the spacer frame by a layer of moisture impervious sealant. After the sheets and the spacer frame are assembled, the sheets are urged toward one another to flow the sealant to seal the space between the sheets.
