  • Patent number: 4089143
    Abstract: A method of converting single pane glass to multiple pane hermetically sealed insulating glass without removing the existing glass sash and frame by using a preformed elastomeric (neoprene) glazing gasket as a mechanical seal. The preformed neoprene rubber seal glazing gasket is supported on a suitable frame of metal, aluminum, or other construction material. The glazing gasket support frame is attached to the existing sash or frame with suitable fastner. The preformed elastomeric glazing gasket is mechanically compressed against the existing lite of glass by the force of the fastner when the support frame is tightened against the existing sash or frame. This mechanical compression of the preformed elastomeric glazing gasket against the existing lite of glass forms a seal that is impervious to air and water vapor. The preformed elastomeric glazing gasket is grooved for support of the second lite of glass that is required to form the multiple pane hermetically sealed insulating glass unit.

  • Patent number: 4074480
    Abstract: A double-glazed window is readily made by installing onto an existing window a spacing frame containing a desiccant and joining a matching pane of glass to the spacer around the periphery thereof, thereby making an air tight seal about the air between the glass panes, with the desiccant in the spacing frame or in a portion thereof being communicable with the air between the panes so as to remove moisture from it to prevent undesirable condensation. The described double-glazed windows are readily installed by the homeowner, using a kit of materials for construction of the spacing frame and installation thereof.

  • Patent number: 4057945
    Abstract: An improved insulating spacer to reduce the heat transfer between the two panes of glass of double insulated glass comprises an extruded or roll-formed metal spacer together with plastic insulating elements which thermally isolate the metal spacer from the panes of glass while permitting conventional application of the sealant to provide reliable bonding. On one embodiment the plastic insulator comprises an extruded plastic overlay which fits tightly over part of a conventional metal spacer and has projecting contacts which abut the glass. In an alternative design the plastic insulator comprises extruded plastic strips which are attached through grooves in the metal spacer. In both designs the height of the insulating contact element can be selected to correspond to the desired gap width between the two glass plates.

  • Patent number: 4055031
    Abstract: A gasket construction for mounting a plurality of panes or panel members within a frame comprises a gasket member having a one-piece body, and a desiccant material incorporated in the one-piece body. The gasket body has at least one spacer wall section formed integrally therewith to provide a plurality of continuous peripheral grooves for receiving the panel members in parallel, closely spaced planes with an enclosed space formed therebetween. Means are provided for communicating the desiccant material with the enclosed space or spaces to prevent the generation and presence of condensation on the interior surfaces of the panel members.
