Case Study: Pacifica Honolulu
Pacifica Honolulu is a 46-floor building with 41 residential floors and 5 parking floors. Pacifica was planned with one intention in mind; to create an architecturally innovative and beautifully designed structure that provides intimate and private living space perfect for family and friends. When Global Stone Inc., a company located in Vineyard Utah, needed an acoustic underlayment to install under 18 x 18 porcelain tile, they chose CERAZORB.
