Abstract
A threshold assembly includes a unitary compression molded plastic composite body formed to define an upwardly open threshold cap channel, jamb boots at its ends, and a support substrate outboard of the channel. An extruded aluminum sill plate is snapped into place on the plastic body and a vertically adjustable threshold cap is disposed in the upwardly open channel. Drain channels may be formed in the plastic body to direct water outwardly and away from the threshold assembly. The plastic body forms a stable foundation that will not rot, swell, or rack in the presence of moisture and fabrication of the assembly is greatly simplified as compared to traditional threshold assemblies.
