An elongated extruded door sill member is supported by a wood base and includes a sloping top wall and a rear wall connected by integral channel portions and a thermal barrier. The channel portions and barrier cooperate to define an upwardly facing cavity, and strips of resilient closed cell foam material are mounted within the channel portions. A vertically adjustable rail member extends longitudinally within the cavity and has side flanges projecting downwardly into the foam strips to form fluid-tight continuous seals. Opposite end portions of the rail member carry pads of the resilient foam material between the flanges for engaging the strips, the channel portions and the thermal barrier to form fluid-tight seals at the ends of the rail member.
