The Libby Gardner Concert Hall has many GRG and FPR components that were installed by WCI. The parts were fabricated on-site at 1" thick and were then installed by WCI creating a very attractive rippling ceiling that has outstanding acoustic properties In addition to the GRG ceiling and wall, a FRP (fiberglass) movable acoustic wall was installed by WCI around the perimeter of the audience. Two inches of sound absorbent fabric was applied to the fiberglass wall. The lightweight wall can be adjusted up or down to create the desired acoustic effect.
