The present invention relate to a method to produce an insulating glass unit (IGU) comprising the following steps: Forming a first assembly by fastening to a first glass plate (3) an IGU spacer (1) and, apart from said IGU spacer (1), an edge element (2) comprising at least one through hole (10), said edge element (2) being fastened with the help of one of an immediate tack and green strength adhesive (5) or a compressible adhesive seal (8); Fastening by pressing a second glass plate (6) to said first assembly, said second glass plate (6) being fastened to the IGU spacer (1) and to the edge element (2), said edge element (2) being fastened thanks to the other one of an immediate tack and green strength adhesive (5) or a compressible adhesive seal (8); Injecting a structural sealant (9) into said at least one through hole (10) of said edge element (2) to fill up the space between the IGU spacer (1) and the edge element (2).

An insulating glass unit (IGU) comprising at least a first glass plate, a second glass plate, a spacer and an edge element, wherein the spacer is fastened to the first glass plate by a first immediate tack and green strength structural adhesive seal, the edge element is fastened to the first glass plate by a second immediate tack and green strength structural adhesive seal, one of the spacer and the edge element is fastened to the second glass plate by a third immediate tack and green strength structural adhesive seal, and the other one of the spacer and the edge element being fastened to the second glass plate by a compressible adhesive seal.

The present application relates to an insulating glass (1) having at least two glass panes (2, 3) spaced apart from one another. The insulating glass (1) comprises at least one marginal join arranged between the glass panes (2, 3) in the region (8, 9, 10, 11) of edges (4, 5, 6, 7) of said glass panes (2, 3), said marginal join consisting of a spacer (12) and also at least one adhesive. The marginal join comprises a first adhesive at least in the region (8, 9) of two mutually opposite edges (4, 5), said adhesive having a rigidity in the cured state of at least 50 N/mm.sup.2, preferably of at least 100 N/mm.sup.2.

A spacer includes a polymeric hollow profile, including a first and second side wall, a glazing interior wall connecting the side walls to one another; an outer wall arranged parallel to the glazing interior wall and connects the side walls to one another; a cavity surrounded by the side walls, the glazing interior wall, and the outer wall, a moisture barrier on the first side wall, the outer wall, and the second side wall, wherein the moisture barrier includes a multi-layer system having a barrier function including a polymeric layer and an inorganic barrier layer, a metallic or ceramic outer adhesive layer having a thickness of less than 100 nm, a binding layer between the adhesive layer and the multi-layer system and including a polymer selected from oriented propylene, oriented polyethylene terephthalate, biaxially oriented propylene, and biaxially oriented polyethylene terephthalate. The binding layer is directly adjacent the adhesive layer.

A composite glass pane having a first glass pane, a second glass pane, and an intermediate layer arranged between the first and second glass panes is described. The intermediate layer includes one cover layer based on a thermoplastic polymer, and a border seal. The first glass pane is arranged with an offset relative to the second glass pane, the intermediate layer is cut back along at least one edge of the composite glass pane by a border distance, and the border seal is arranged in a border gap delimited by the first glass pane, the second glass pane and the intermediate layer. The border seal contains a polymer fusible with a polymer of the cover layers.

Embodiments herein relate to window spacer assemblies including surfaces with relatively high surface energy. In an embodiment, a window spacer assembly is included. The window spacer assembly including a spacer body having an inner surface, an outer surface, and lateral surfaces. The window spacer assembly further includes a first sealant disposed on the lateral surfaces. Portions of the window spacer assembly such as an outer surface or lateral surface of the spacer body and/or a moisture vapor barrier layer disposed over the outer surface can be treated to have a higher surface energy. Other embodiments are also included herein.

A composite glass pane having a first glass pane, a second glass pane, and an intermediate layer arranged between the first and second glass panes is described. The intermediate layer includes one cover layer based on a thermoplastic polymer, and a border seal. The first glass pane is arranged with an offset relative to the second glass pane, the intermediate layer is cut back along at least one edge of the composite glass pane by a border distance, and the border seal is arranged in a border gap delimited by the first glass pane, the second glass pane and the intermediate layer. The border seal contains a polymer fusible with a polymer of the cover layers.

Methods and vacuum insulated glazing units are provided. The methods include providing a first pane, applying a primary sealant to the first pane adjacent to and along a perimeter of the first pane, positioning support pillars on the first pane, positioning an evacuation tube on the first pane, positioning a second pane on the support pillars, heating the primary sealant with a laser beam sufficient to sinter the primary sealant to form a primary seal joining the first and second pane, evacuating an intermediate space defined between the first and second pane, and the primary seal to produce a low-pressure environment in the intermediate space by drawing gas from the intermediate space through the evacuation tube, and sealing the evacuation tube and thereby hermetically sealing the intermediate space within the first and second pane, the primary seal, and the evacuation tube to maintain the low-pressure environment therein.

The present invention relates to a system for the production of a sealant composite made of a primary sealing material and a curable secondary sealing material, the use of the system for the production of insulating glass or solar modules, an edge seal for the production of double-pane or multi-pane insulating glass or solar modules comprising the sealant composite and an insulating glass unit comprising at least two glass panes and the edge seal.
