摘要

A method of replacing an existing fenestration unit secured in a rough opening in a wall having a finished exterior includes releasing an existing fenestration unit from the wall by cutting around the existing fenestration unit, including cutting into the finished exterior of the wall and through a perimeter portion of the existing fenestration unit to release the fenestration unit from the wall. The method also includes removing the existing fenestration unit from the rough opening in the wall, installing a water management system along a sill of the rough opening, and inserting a new fenestration unit into the rough opening.

1. A method of replacing an existing fenestration unit secured in a rough opening in a wall having a finished exterior, the method comprising:
releasing an existing fenestration unit from the wall by cutting around the existing fenestration unit, including cutting into the finished exterior of the wall and through a perimeter portion of the existing fenestration unit to release the fenestration unit from the wall; removing the existing fenestration unit from the rough opening in the wall; placing a sill liner adjacent a sill of the rough opening such that a sill liner channel faces upward toward the center of the rough opening, placing a head liner adjacent a head of the rough opening such that a head liner channel faces upward away from the center of the rough opening, the head liner including first and second connection ports at each end of the head liner channel; and placing a first jamb liner adjacent a first jamb of the rough opening such that a first jamb liner channel is aligned with the sill liner channel and the first connection port of the head liner channel, such that fluid can flow from the head liner channel to the first jamb liner channel via the first connection port, and then from the first jamb liner channel to the sill liner channel, placing a second jamb liner adjacent a second jamb of the rough opening such that a second jamb liner channel is aligned with the sill liner channel and the second connection port of the head liner channel, such that fluid can flow from the head liner channel to the second jamb liner channel via the second connection port, and then from the second jamb liner channel to the sill liner channel; inserting a new fenestration unit into the rough opening; and securing the new fenestration unit in the rough opening.
