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. Communication is established through the cap through which vacuum is applied and the communication is closed off to form a permanent final closure containing partial vacuum within the chamber.

A sealed insulating glass unit, comprising an assembly of three panes of glass of the same areal dimensions in registering parallel spaced relationship with a plurality of spacer members sandwiched between adjacent panes, the spacer members being discs of slightly resilient plastic material having a diameter from about 0.0625 of an inch to about 0.0625 of an inch and an initial thickness from about 0.020 to 0.040 of an inch and slightly compressed, the spacer members being spaced-apart from about 1.5 to about 2.0 inches center-to-center between each pair of panes and the spacer members between different pairs of panes being staggered so that each spacer member between respective paris of panes is spaced-apart from any spacer member between the other pair of panes, the sealing cap being a mastic ribbon of plastic sealant highly adhesive to the edges of the panes and impermeable to gases whereby it provides a permanent vacuum-retaining seal, the spaces between the panes being under a permanent partial vacuum within the range from about 43 to about 76 cm of mercury, a layer of metal foil covering the outside of the mastic ribbon cap about the entire periphery of the unit, the unit having a total thickness within the rage from about 6.8 to about 9.8 mm. A sealed insulating glass unit, comprising a central pane and a pair of outer panes with a plurality of spacer members sandwiched between them, sealing means for establishing a pair of hermetically sealed chambers, each of said chambers between a respective one of said outer panes and said central pane, the chambers being under partial vacuum whereby implosive pressure urges the panes together, the spacer members between the central pane and one of the outer panes being staggered from those between the central pane and the other outer pane.
