Abstract:
1. A contain-and-drain sill comprising: a sill body having a threshold cap positioned to underlie a closed door of an entryway in which the contain-and-drain sill is installed and defining a generally hollow sill interior, the sill body having an exterior edge defining a nosing; the nosing including first and second attachment features extending along the length of the nosing; the nosing being spaced from the threshold cap a distance sufficient to ensure that the first and second attachment features of the nosing are positioned beyond framing and trim beneath an opening in which the contain-and-drain sill is installed; a separate sill extension attached to the nosing and extending from the nosing of the sill body to a position below the sill body, the sill extension having a generally hollow sill extension interior, opposed ends, a first clip engaged with the first attachment feature of the nosing forming a first interface between the sill nosing and the sill extension and a second clip engaged with the second attachment feature of the nosing forming a second interface between the sill nosing and the sill extension; caulking or silicone along the first interface formed by the first clip and the first attachment feature and forming a substantially watertight seal; caulking or silicone along the second interface formed by the second clip and the second attachment feature and forming a substantially watertight seal; a first end cap attached to one end of the sill extension, the first end cap closing the one end and forming a substantially watertight seal at the one end of the hollow sill extension interior; a second end cap attached to the opposed end of the sill extension, the second end cap closing the opposed end and forming a substantially watertight seal at the opposed end of the hollow sill extension interior; at least one opening in the nosing between the first and second attachment features and establishing a flow path between the generally hollow sill interior and the generally hollow sill extension interior; and at least one weep hole in the sill extension below the level of the at least one opening in the nosing and establishing a flow path between the generally hollow sill extension interior and a environment.
