A shutter assembly includes a stile having a solid core and a plastic outer cover. Holes are formed in the plastic outer cover and aligned with an axial groove formed in the solid core to receive a slotted louver pin. The louver pin includes a pair of arms that provide a sufficient compression fit in the axial groove of the stile while enabling each louver to rotate freely. Separate stile end caps are formed to be flush with the edges of the ends of the plastic cover. Each louver includes louver edges and opposite end caps which are substantially flush with the louver edges. A method of manufacturing a shutter assembly is also provided.
