1. A method of attaching a retention member to an insulating glazing unit comprising:
placing a spacer unit between a first pane of glass and a second pane of glass to form the insulating glazing unit;
applying a sealant to an exterior portion the spacer unit between the first pane of glass and the second pane of glass;
applying an adhesive composition to a channel defined by the first pane of glass, the second pane of glass, and the sealant, wherein the volume of adhesive composition applied is greater than the volume of the channel defined by the first pane of glass, the second pane of glass, and the sealant such that a portion of the adhesive composition is beyond an outer periphery of a proximal end of the first pane of glass and a proximal end of the second pane of glass,
shaping or removing a portion of the adhesive composition that is beyond the outer periphery of the proximal end of the first pane of glass and the proximal end of the second pane of glass; and
mounting the retention member onto perimeter edges of at least one of the first pane and the second pane while the adhesive composition is capable of bonding;
wherein at least a portion of the retention member that is disposed laterally between the first pane of glass and the second pane of glass is embedded within the adhesive composition.
