A window is disclosed which has a window frame with a generally Z-shaped flange. The Z-shaped flange has an inwardly facing generally V-shaped pocket. A window pane is provided which has generally V-shaped edges adapted to fit within the inwardly facing V-shaped pocket in the flange section. A track is disposed between the window pane and the window frame to permit sliding therebetween. The dimensions of the mating V-shaped pockets and V-shaped edge are such that upon installation the flat face of the window pane is flush with the outer leg of the Z-shaped flange member.
