System and methods of attaching retention members to insulating glazing units

A method of attaching a retention member to an insulating glazing unit comprising:

• obtaining the insulating glazing unit, the insulating glazing unit comprising a first pane, a second pane, a spacer unit disposed between the first pane and the second pane, and a sealant disposed external to the spacer and between the first pane and the second pane, wherein the first pane is a laminate pane comprising a polymeric material disposed between a first glass layer and a second glass layer;
• applying an adhesive composition to at least one of a perimeter of the insulating glazing unit;
• applying the retention member to the perimeter edges of the first pane and the second pane;
• and
• shaping or removing a portion of the adhesive composition that is external to a channel;
• wherein applying an adhesive composition to the perimeter of the insulating glazing unit comprises applying the adhesive composition into the channel disposed between the first pane and the second pane and to the outside of the spacer unit, wherein the volume of adhesive composition applied is greater than the volume of the channel disposed between the first pane and the second pane and to the outside of the spacer unit such that a portion of the adhesive composition is beyond an outer periphery of a proximal end of the first pane and a proximal end of the second pane;
• wherein the adhesive composition contacts the polymeric material of the first pane.
