A two-section slat for use in a roll-type shutter is formed of a channel-shaped extrusion section having a hook formation at its upper end and a receiving channel for the next slat hook along its lower edge. The channel is overlapped by a cover section which is engaged and interlocked with the channel section at the upper edge, lower edge and in the central portion of the cover section. The two sections are formed with interlocking means which hold the two sections together under resilient pressure to form a hollow, substantially rigid, flat bar. The cover section may have a preselected color or texture which differs from the color and texture of the channel section. Thus, the slat, having two different colors or textures can match the decor of a interior room of a dwelling while also matching the appearances of numerous shutters exposed to view on the exterior of the building.
