<p>A reglet channel having an unimpaired apron depending from the outer edge of its upper flange down to the level of the outer edge of its lower flange to protect the sealing compound in the interior of the channel from the deleterious effects of rain and sunlight, i.e., softening, seepage, drying-out and shrinkage. For ease in manufacture by extrusion processes, the lower marginal portion of the apron may be integral with the lower flange of the channel and may be provided with a single groove in its outer surface extending parallel and adjacent to the outer edge of the lower flange. After installation in a wall the reglet channel may be slit open along this groove to provide access to its interior for engagement of the retaining lip of the flashing. The apron, if unimpaired, provides the additional advantage of holding the installed flashing in position without the need for retaining wedges. Thus, it saves the cost of special retaining components for the flashing and the cost of labor fox the installation of these components.</p> |
