Abstract: Embodiments herein relate to methods for attachment of a retention member to an insulating glazing unit, resulting structures, and systems for the accomplishing the same. In some embodiments, a method of attaching a retention member to an insulating glazing unit can include placing a spacer unit between a first pane of glass and a second pane of glass to form the insulating glazing unit and applying an adhesive composition to at least one of a perimeter of the insulating glazing unit and the retention member. The method can further include mounting the retention member onto perimeter edges of at least one of the first pane and the second pane. Other embodiments are also included herein.

Abstract: Embodiments herein relate to a system and method for retaining an insulated glass subassembly including a laminated layer of glass within a frame of a fenestration unit providing protection against wind borne debris. A fenestration unit can include a frame member defining a channel with a lower end and an attachment surface thereon along with a glass subassembly including a proximal end received and seated within the channel and an outside facing surface of the exterior pane proximate the lower end of the channel. A retention member can engage the interior laminate pane, and a glazing material can be on the attachment surface at the lower end of the channel. The outside facing surface of the glass subassembly can be attached to the channel of the frame member with the glazing material. In various embodiments, methods of making a retention member are included herein. Other embodiments are also included herein.
