Abstract
Magnetic forces are applied to a side of a spacer frame mounted on a glass sheet to maintain the side of the spacer frame in alignment i.e. the plane containing base of the spacer frame perpendicular to the plane containing the surface of the glass to which the spacer frame is adhered. Thereafter a glass sheet is mounted on the other surface of the spacer frame. The sheets are adhered to the spacer frame by a sealant layer. After the sheets are assembled, the sheets are urged toward one another to flow the sealant to seal the space between the sheets.
