In an island type refrigeration display cabinet, a top aperture containing two oppositely disposed louvers for discharging oppositely directed coplanar air curtain sections, to form a single air curtain of multiple section in the top aperture of the display cabinet. Preferably, the cabinet also includes means for withdrawing air from the interior display space of the cabinet and forcing the air through a bifurcated conduit. Each bifurcation of the conduit is flowably connected to one of the respective louvers in the top opening of the display cabinet. Each bifurcation of the conduit also includes means for refrigerating the air flowing through the conduit to the louvers.
