Inventor: VAGEDES MICHAEL
IPC: E06B7/02
Filed: 2006-07-17
Abstract: A vent is formed from vent panels which are configured with one or more slats. The custom-sized gable vent is formed by cutting sections of the slatted vent panel. The sections of slatted vent panel interfit to provide the desired height of the vent. Trim channel is cut and sized to surround the vent. The structure is assembled by fastening the individual components to the wall of a building. The trim channels can be either J channel, when the vent is intended to abut another surface, or T channel, when vinyl siding abuts the vent. This provides the builder the flexibility to form a gable vent of a desired size and shape at the job site. Further, the slatted vent panels are designed to connect directly to siding. This allows the slatted vent panels to be attached to the wall of a building in the same manner as siding.
