Abstract

Two window panes are each laminated on one side with polyethylene terephthalate film. The film sides are faced towards each other and a spacer of ¼ to {fraction (9/10)} inch width is placed between the coated surfaces of the window panes. An inboard surface of the spacer is positioned level with a top of the framing system. The area between an outside edge of the spacer and the edge of the window panes is backfilled with silicone sealant. The formed composite is then secured in a glazing channel on the window frame with silicone applied in the glazing channel of the window frame.

Claims

1. A method of forming and mounting an insulated impact-resistant glass composite into a window frame, the steps comprising:

coating one side surface of two window panes having a predetermined thickness with a laminated safety film extending to all edges of the window panes;

facing the side of the window panes containing the laminated safety film towards each other while inserting a ¼

to {fraction (9/16)} inch wide spacer inboard from the edges of the window panes between the laminated surface of the window panes while providing an inboard edge of the spacer in a site line with the window frame;

backfilling a structural silicone from an outboard edge of the spacer to the edges of the window panes to form a two window pane composite;

placing a silicone tape or silicone composition in a glazing channel of the window frame below the sight line of the window frame;

inserting the window pane composite in the glazing channel of the window frame while maintaining the silicone tape or silicone composition between an inside surface of the window frame and the surface of the window pane composite opposite the coated surface; and

installing a snap in glazing bead together with filling any gap between the glazing bead and the window pane composite with structural silicone up to the site line of the window frame.

2. The method according to claim 1 wherein the laminated safety film is provided as a polyethylene terephthalate film.

3. The method according to claim 2 wherein the polyethylene terephthalate film is provided in at least three plies having a thickness of at least 0.012 inch.

4. The method according to claim 1 wherein the outboard edge of the spacer is mounted about ¼

inch from the edges of the window panes.

5. A method of forming and mounting an insulated impact resistant glass into a window frame, the steps comprising:

applying a multiple ply laminated safety film to one surface of two window panes of predetermined thickness, the safety film extending to the edges of each window pane;

inserting a spacer between the window pane surfaces receiving the safety film, an inboard edge of the spacer configured to extend no further than a site line of a window frame in which the window panes are to be mounted, an outboard edge of the spacer extending no closer than ¼

inch from the edges of the window panes;

applying a structural glazing compound from the outboard edge of the spacer to the edges of the window panes;

providing the window frame with a glazing channel below the site line and applying a glazing tape to a surface of the glazing channel;

inserting the window panes with spacer into the glazing channel, the surfaces of the window pane opposite the safety film juxtaposed to the glazing tape;

installing a glazing bead; and

filling any gap between the glazing bead and the window panes with a glazing compound up to the site line of the window frame.

6. The method according to claim 5 wherein about three ply of polyethylene terephthlate is provided as the safety film.

7. The method according to claim 6 wherein the polyethylene terephthlate laminated film is provided at a thickness of 0.008 to 0.020 inch.

8. The method according to claim 7 wherein the polyethylene terephthlate laminated film is provided at a thickness about 0.012 inch.

9. The method according to claim 5 wherein the spacer is provided at a thickness between the window panes of ¼

to {fraction (9/16)} inch.

10. The method according to claim 9 wherein the spacer is provided at a thickness between the window pane of ¼

to ½

inch.

11. The method according to claim 5 wherein the structural glazing compound applied is silicone.

12. The method according to claim 5 wherein the structural glazing compound applied is buytal.

13. The method according to claim 5 wherein the glazing tape is a silicone tape.

14. The method according to claim 5 wherein the window panes are provided ⅜

inch thick.
