Abstract

A window glazing assembly that can convert an existing or already-installed window, or be used to assemble new construction windows as a multi-pane or multi-glazed window unit, is provided herein. In particular, the glazing assembly includes an attachment assembly (e.g., peel-and-stick double-sided adhesive tape) and one or more glazing layers. Some embodiments further include a spacer assembly comprising a plurality of spacer bars that may be individually installed, e.g., one by one, around the perimeter of the window such as, to the window sash, window frame, or glass window pane, itself. The glazing layer(s) can then be secured or adhered to the spacer assembly, for example, around the perimeter thereof. Some embodiments may include additional or intermediate glazing layers, providing additional insulating airspaces and enhanced performance.

Claims

1. A multi-glazed window assembly for new construction or replacement windows, said multi-glazed window assembly comprising:

a plurality of glazing layers comprising an inner glazing layer, an outer glazing layer and at least one intermediate glazing layer, said plurality of glazing layers being disposed in a spaced relation to one another to define a plurality of insulating airspaces, and

a rigid spacer assembly disposed between said inner glazing layer and said outer glazing layer, wherein said rigid spacer assembly comprises at least one rigid spacer bar connected at one end to an inward surface of said inner glazing layer and at another end to an inward surface of said outer glazing layer,

said rigid spacer assembly further comprising at least one rigid intermediate spacer bar attached to said at least one spacer bar and said at least one intermediate glazing layer, wherein said at least one rigid intermediate spacer bar and said at least one rigid spacer bar are separate pieces,

wherein said rigid spacer assembly and said plurality of glazing layers transfer structural roof loads of a building, within which said multi-glazed window assembly is installed, and wherein said multi-glazed window assembly is installed within the building without a window header.

2. The multi-glazed window assembly as recited in claim 1 where said plurality of glazing layers comprise at least one curved surface, and wherein said rigid spacer assembly comprises at least one spacer bar comprising an at least partially curved surface configuration corresponding to said at least one curved surface of said plurality of glazing layers.

3. The multi-glazed window assembly as recited in claim 1 further comprising a heat transfer conduit disposed within at least one of said plurality of insulating airspaces;

said heat transfer conduit comprising a heat transfer fluid disposed therein, providing radiant heat collection and transfer.

4. A multi-glazed window assembly, said multi-glazed window assembly comprising:

a plurality of glazing layers comprising an inner glazing layer, an outer glazing layer and at least one intermediate glazing layer, said plurality of glazing layers being disposed in a spaced relation to one another to define a plurality of insulating airspaces,

a spacer assembly disposed between said inner glazing layer and said outer glazing layer, wherein said spacer assembly comprises at least one spacer bar connected at one end to an inward surface of said inner glazing layer and at another end to an inward surface of said outer glazing layer,

said spacer assembly further comprising at least one intermediate spacer bar attached to said at least one spacer bar and said at least one intermediate glazing layer, and

at least one ventilation tube passing through said outer glazing layer, through said at least one intermediate glazing layer, and through said inner glazing layer, wherein said ventilation tube is structured to provide a flow of air from an outward surface of said outer glazing layer, through said at least one intermediate glazing layer, and to an opposite, outward surface of said inner glazing layer.

5. The multi-glazed window assembly as recited in claim 4 wherein said at least one intermediate spacer bar and said at least one spacer bar are separate pieces.

6. A multi-glazed window assembly for new construction or replacement windows, said multi-glazed window assembly comprising:

a plurality of glazing layers comprising an inner glazing layer, an outer glazing layer and at least one intermediate glazing layer, said plurality of glazing layers being disposed in a spaced relation to one another to define a plurality of insulating airspaces,

a rigid spacer assembly disposed between said inner glazing layer and said outer glazing layer, wherein said rigid spacer assembly comprises at least one rigid spacer bar connected at one end to an inward surface of said inner glazing layer and at another end to an inward surface of said outer glazing layer,

said rigid spacer assembly further comprising at least one rigid intermediate spacer bar attached to said at least one spacer bar and said at least one intermediate glazing layer, wherein said at least one rigid intermediate spacer bar and said at least one rigid spacer bar are separate pieces, and

at least one ventilation tube passing through said outer glazing layer, through said at least one intermediate glazing layer, and through said inner glazing layer, wherein said ventilation tube is structured to provide a flow of air from an outward surface of said outer glazing layer, through said at least one intermediate glazing layer, and to an opposite, outward surface of said inner glazing layer.
