City of Hope Hospital in Duarte, California, uses 21,000 square feet of GreenGirt Max CMH™ over metal studs, behind aluminum flat plate cladding, with mineral wool insulation. It is an oncology hospital, part of the City of Hope medical campus. It was designed by DAG Architects and built and installed by Ehmcke Sheet Metal Corp.

A hospital is held to stricter life-safety requirements than almost any other building type, because many of its patients cannot evacuate quickly. That requirement shapes the wall assembly. Continuous insulation that is itself non-combustible is the safer specification for a healthcare building, forming an unbroken insulating layer that does not support combustion. Behind a flat aluminum exterior suited to a medical institution, that same continuous layer maintains the steady interior conditions patient care depends on.
