The architect designed fiberglass-molded, precast concrete tiles as the building’s rainscreen. The tiles are double convex curves, creating a pillowed effect for each tile. This gives a quilt-like feeling to the façade. There are seven square tiles with seven different values of convexity, ranging from pillowed to flat in profile. An eighth L-shaped, pillowed tile was used to allow for windows. Fiberglass molds are inexpensive to make and can produce more units than Styrofoam or rubber molds. The fiberglass mold gives the precast concrete a smooth and slightly glossy finish.
