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.
