Abstract
Installation systems and methods for fenestration units configured to be set into a rough opening (RO) from interior side of a building structure or wall. The fenestration units may include a retention system coupled to the frame and operable to exert a retention force on the fenestration unit to maintain positive engagement of the fenestration unit with the rough opening framing and resist extraction of the fenestration unit from the rough opening upon insertion of the fenestration unit in the rough opening from the interior side of the rough opening.
Claims20
A fenestration unit having an interior side and an exterior side configured to be installed in a rough opening in a structure, the fenestration unit comprising:
- a frame having a perimeter, a front side, a back side opposite the front side;
- and
- a weather seal system secured to the perimeter of the frame, the weather seal system including,
- a fin assembly configured to transition from a first, folded configuration toward a second, projecting configuration in which the fin assembly projects outward relative to the front side of the frame, and
- a retaining assembly releasably securing the fin assembly in a constrained state in the first, folded configuration.
A method of installing a fenestration unit in a rough opening in a structure comprising:
- inserting an exterior side of the fenestration unit into the rough opening from an interior side of the rough opening;
- releasing a retaining assembly secured to a perimeter of a frame of the fenestration unit such that a weather seal system secured to the perimeter transitions from a constrained state in which a fin assembly of the weather seal system is compressed toward the frame to a deployed state in which the fin assembly projects radially outward from the perimeter of the frame;
- and
- securing the fenestration unit in the opening in the structure with the fin assembly abutted against an exterior surface of the structure.
