Abstract: A sealed insulated glass unit is made up of an assembly of at least two panes of glass of the same areal dimensions in registering parallel spaced relationship. Small spacer members are sandwiched between the panes to maintain their spacing. A cap of impervious material covers and adheres to the peripheral edges of the panes and bridges the gap between them to form a hermetically sealed chamber. The chamber is under partial vacuum whereby implosive pressure urges the panes and cap together in a cohesive unit. A method of making the unit involves forming an assembly of at least two panes having registering peripheral edges while inserting and maintaining in place between them a plurality of small thin flat spacing members. The assembly is maintained in place while the cap of sealing material is applied to the entire periphery to adhere to the edges of the panes and to bridge the gap between them to form a closure establishing a closed chamber between the panes.

Abstract: At least two generally parallel transparent panes are provided with a spacer between them at their perimeter, which spacer holds a fire protection material which includes an intumescent material, an opaque finely divided material in a solid, liquid or gel-like form.

The spacer itself may be composed of fire protection material or may be a channel holding such material or hollow tubular structure with openings or may be a combination of these forms. The invention also includes the method of placing fire protection material in the spacer between panes of glazing material and when temperature reaches a predetermined level expelling the fire protection material into the space between the panes and coating their internal surfaces with an opaque coating.

Abstract: An insulated glass unit formed from a pair of glass sheets, one of which has an electroconductive coating, i.e. a first sheet, is fabricated by positioning the first sheet on a vacuum support and the other sheet, i.e. second sheet, spaced above the first sheet a sufficient distance therefrom to prevent arcing during electrical heating of the marginal edges of the second sheet. After the marginal edges of the second sheet are heated to a temperature sufficient to cause sagging of the marginal edges, the two sheets are brought together to join the marginal edges by fusion.

Thereafter, the sheets are separated from one another and air moved between the sheets to bloom the edes. After blooming the edges, the joined glass sheets are annealed, and an insulating gas moved into the airspace through a pore hole.

Abstract: A method of producing multi-pane glass units having a non-air gas in the interpane space. The method includes the steps of assembling several glass units, each of which has a pair of spaced glass panes and a peripheral spacer. A separator device is interposed between one of the panes and the peripheral spacer of each of the units. When the units have been so assembled, a vacuum is drawn on the units in an evacuable chamber to remove substantially all of the air from the interpane spaces. The chamber is then refilled with a suitable gas, such as argon, to refill the interpane space of each of the units. The separator is then removed from the glass units, to close the opening between the pane and the peripheral spacer of each unit, thereby completely sealing the interpane space of each unit from the vacuum chamber environment. The units can then be removed from the vacuum chamber and further processed.
