Abstract:
1. A method of installing a framed object into a rough opening of a building, the rough opening having sides that define an interior, the method comprising: a) attaching a flexible barrier to a plurality of the sides of the rough opening, the flexible barrier extending toward the interior of the rough opening; b) inserting the framed object into the interior of the rough opening creating a space between the framed object and the rough opening; c) during the insertion step, creating contact between the framed object and at least a first portion of the flexible barrier thereby causing the first portion of the flexible barrier to bend during insertion; d) fixing the framed object in the rough opening so that the first portion of the flexible barrier remains in a bent position, whereby the flexible barrier extends into the space and divides the space into an external channel on an external side of the flexible barrier and an internal space on an internal side of the flexible barrier; and e) after inserting the framed object into the rough opening, inserting foam into the internal space up to and abutting the flexible barrier, wherein the flexible barrier blocks the foam from filling the external channel.
