Base molding

A wall comprising:

• a supporting wall structure,
• a base molding affixed to said wall structure at or near a floor, said base molding comprising an integral unitary structure formed by extruding a plastic material and comprising:
• a rear wall having a lower end,
• a front wall having a lower end,
• a bottom wall connecting the lower end of said front wall and the lower end of said rear wall in spaced-apart relationship, the outer surface of said bottom wall being concave and terminating in a toe at the junction of said bottom wall and said front wall and having sealant sealing said base molding to said floor,
• a panel support web connecting said front and rear walls at a position spaced from said bottom,
• a back nailing flange extending as an integral portion of said rear wall above its connection with said panel support web, and
• a face flange extending from said front wall as an integral portion thereof and above said panel support web,
• said back nailing flange, said panel support web, and said face flange cooperating to define a channel,
• a plurality of wall panels each having its lower edge engaged in said channel, and
• means fastening said back nailing flanges to said supporting structure.

An inner wall corner structure comprising:

• A. an inner corner support comprising:
• 1. a vertical angle member comprising a pair of perpendicularly oriented flanges having inner and outer surfaces,
• 2. a pair of channel members in perpendicular relationship one affixed to the outer surface of each of the flanges of said vertical angle member,
• B. a plurality of base moldings arranged end-to-end each comprising an integral unitary structure formed by extruding a plastic material and comprising:
• 1. a rear wall having a lower end,
• 2. a front wall having a lower end,
• 3. a bottom wall connecting the lower end of said front wall and the lower end of said rear wall in spaced-apart relationship, the outer surface of said bottom wall being concave and terminating in a toe at the junction of said bottom wall and said front wall, and having a sealant sealing said base molding to said floor,
• 4. a panel support web connecting said front and said rear walls at a position spaced from said bottom
• 5. a back nailing flange extending as an integral portion of said rear wall above its connection with said panel support web, and
• 6. a face flange extending from said front wall as an integral portion thereof and above said panel support web,
• said back nailing flange, said panel support web, and said face flange cooperating to define a channel adapted to receive the lower edge of a wall panel and to support said panel at a position elevated above said floor,
• said rear wall, said front wall, said bottom wall, and said panel support web cooperating to define a rectangular tubular chamer, the channel members of said corner support being disposed within the tubular chambers of said base moldings,
• C. a wall support having the back nailing flanges of said base moldings affixed thereto, and
• D. a plurality of panels having lower edges, said lower edges being disposed and retained within the channels of said base moldings.

An outer wall corner structure comprising:

• A. an inner corner support comprising:
• 1. a vertical angle member comprising a pair of perpendicularly oriented flanges having inner and outer surfaces,
• 2. a pair of channel members in perpendicular relationship one affixed to the inner surface of each of the flanges of said vertical angle member,
• B. a plurality of base moldings arranged end-to-end each comprising an integral unitary structure formed by extruding a plastic material and comprising:
• 1. a rear wall having a lower end,
• 2. a front wall having a lower end,
• 3. a bottom wall connecting the lower end of said front wall and the lower end of said rear wall in spacedapart relationship, the outer surface of said bottom wall being concave and terminating in a toe at the junction of said bottom wall and said front wall, and having a sealant sealing said base molding to said floor,
• 4. a panel support web connecting said front and said rear walls at a position spaced from said bottom,
• 5. a back nailing flange extending as an integral portion of said rear wall above its connection with said panel support web, and
• 6. a face flange extending from said front wall as an integral portion thereof and above said panel support web,
• said back nailing flange, said panel support web, and said face flange cooperating to define a channel adapted to receive the lower edge of a wall panel and to support said panel at a position elevated above said floor,
• said rear wall, said front wall, said bottom wall, and said panel support web cooperating to define a rectangular tubular chamber, the channel members of said corner support being disposed within the tubular chambers of said base moldings,
• C. a wall support having the back nailing flanges of said base moldings affixed thereto, and
• D. a plurality of panels having lower edges, said lower edges being disposed and retained within the channels of said base moldings.
