Abstract
A multi-paned fenestration unit in which the glass panes are manufactured directly into the support structure without first manufacturing an insulated glass unit. The support structure is designed to provide the structural support for the glass panes without a separate spacer.
Claims6
A method of manufacturing a fenestration unit, the fenestration unit including a first glass pane and a second glass pane each comprising an inside surface, an outside surface and an edge;
- each of the inside surfaces having a border portion and an inner portion and each of the outside surfaces having a border portion and an inner portion, the method comprising:
- constructing a first sash section having a first receiving surface, the first receiving surface including a raised portion at an inner edge;
- constructing a second sash section having a second receiving surface and a third receiving surface;
- constructing a third sash section having a fourth receiving surface, the fourth receiving portion including a raised portion at an inner edge;
- depositing a first secondary sealant on at least one of the group of the first receiving surface and the border portion of the outside surface of the first glass pane;
- placing the border portion of the outside surface of the first glass pane on the first receiving surface after depositing the first secondary sealant;
- depositing a first primary sealant on at least one of the group of the second receiving surface and the border portion of the inside surface of the first glass pane;
- placing the second receiving surface on the border portion of the inner surface of the first glass pane after depositing the first primary sealant;
- depositing a second primary sealant on at least one of the group of the third receiving surface and the border portion of the inside surface of the second glass pane;
- placing the border portion of the inside surface of the second glass pane on the third receiving surface after depositing the second primary sealant;
- depositing a second secondary sealant on at least one of the group of the fourth receiving surface and the border portion of the outside surface of the second glass pane;
- placing the fourth receiving surface on the border portion of the outside surface of the second glass pane after depositing the second secondary sealant.
