A louver door construction includes a spaced pair of vertical stiles and a louver unit which is formed as a one-piece extruded plastic sheet secured between the vertical stiles. The louver unit includes a plurality of integrally connected louver sections, each having an elongated inclined portion and an elongated horizontal portion. The inclined portions of the louver sections extend upwardly and rearwardly from front edges of the corresponding horizontal portions. The inclined portion of one louver section has a distal upper edge which is connected integrally with a rear edge of the horizontal portion of an adjacent louver section. The inclined portions of the louver sections are parallel with one another, while the horizontal portions of the louver sections are parallel with one another. The horizontal portions of some of the louver sections are formed with a series of slots which permit flow of air through the louver unit. Top and bottom rails are mounted on and extend between upper and lower ends of the vertical stiles.
