ABSTRACT OF THE DISCLOSURE The improved folding door and door frame assembly includes a door frame having a horizontal top channel member adapted to receive a number of depending door slides, and a vertical side frame member below the channel member. The assembly also includes a folding door formed of an array of interconnected, parallel, vertically extending polyvinyl chloride slats arranged in side by side relation. The slats have small staple fibers substantially uniformly distributed throughout the body thereof to give the slats a translucent sandy appearance and feel. Each slat in the array preferably is corrugated to provide a number of integral parallel segments. Each slat has an integral side folding hinge extending along the length of one side thereof and a hinge- receiving slot or groove along the length of the opposite side of the slat. The slats are interconnected through the side hinges and grooves. The slat on one side of the array is connected to the door side frame through its side hinge, while the slat on the opposite side of the array is connected to a handle-bearing side panel through the side hinge of the panel. Preferably, the panel and frame are textured to match the slats. The aforementioned slides are connected to the upper ends of the side panel and slats to hold them in the vertical position in the frame. The improved method includes forming the slats from a pelletized and extruded mixture of polyvinyl chloride, titanium dioxide, plasticizer, tribasic lead sulfate, stearic acid and the staple fibers of less than 2 mm. length and of cotton, flax, wool or a mixture thereof.
