Washington University School of Medicine Pedestrian Bridge in St. Louis, Missouri, uses 8,000 SF of GreenGirt Max CMH™ over steel studs, behind ACM panel cladding, with mineral wool insulation. It is an enclosed pedestrian bridge connecting buildings on the medical campus, designed by Cannon Design, built by KAI Enterprises, and installed by Hyde Sheet Metal.

An enclosed pedestrian bridge is exposed to the weather on both long faces and underneath rather than on a single elevation, so heat escapes from far more of its surface than a typical wall, and any thermal bridge through the framing is felt across a conditioned space people walk through. GreenGirt Max CMH carries the ACM panels on a thermally broken support over a continuous mineral wool layer, keeping the insulation unbroken around the connector so the crossing stays comfortable.
