Fenestration unit with interior installation features and associated systems and methods

A method of installing a fenestration unit, the method comprising:

• performing an interior installation phase from an interior of a building structure having an exterior opposite the interior of the building structure, the building structure including a rough opening having a rough opening frame, the rough opening frame having a center, a perimeter extending around the center, and a support surface facing toward the center and substantially orthogonal to an interior surface of the building structure that faces toward the interior of the building structure, the interior installation phase including,
• arranging a fenestration unit in the rough opening from the interior of the building structure using an insertion force such that the fenestration unit exerts a retention force on the rough opening frame that is greater than the insertion force to maintain positive engagement of the fenestration unit with the rough opening frame and resist extraction of the fenestration unit from the rough opening after insertion of the fenestration unit in the rough opening such that the fenestration unit remains stationary in the rough opening without use of fasteners,
• adjusting a position of the fenestration unit within the rough opening,
• securing the fenestration unit to the rough opening frame with a plurality of fasteners such that an anchoring clip coupled to a perimeter of the fenestration unit contacts the interior surface of the building structure, and
• insulating a gap between the rough opening frame and the fenestration unit;
• and
• performing an exterior installation phase from an exterior side of the building structure independently from the interior installation phase, the exterior installation phase including, weather sealing the fenestration unit to an exterior surface of the building structure.
