Water Intrusion Prevention Method and Apparatus

摘要

A method and device are presented that creates a channel adjacent a nailing flange of a window in between the window and the rough opening that receives the window. The channel is created by establishing a barrier that prevents foam insulation inserted into the space between the window and the rough opening from reaching the nailing flange. The channel then ensures proper drainage of water that enters the window cavity down to the window sill. A gasket is presented that can be attached to the window or the rough opening to create the barrier. Alternatively, a disintegrating object or a wicking object can be used to impede the flow of insulation foam and to create the appropriate channel. The present invention is equally applicable to doors or other framed objects received into the exterior shell of a building.

主权项

1. A method of installing a framed object into a rough opening of a building comprising:
a) inserting the framed object into the rough opening, thereby creating a space between an exterior face of the framed object and the rough opening; b) positioning a barrier in the space thereby dividing the space between an external channel on the external side of the barrier and an internal space on the internal side of the barrier; and c) after inserting the framed object into the rough opening, inserting foam into the internal space up to the barrier, wherein the barrier prevents the foam from filling the external channel.
