Knutson Construction

The Children’s Hospital and Clinics of Minnesota Minneapolis campus were constructed in two phases. Empirehouse was contracted to provide the exterior curtainwall and composite metal-panel system cladding for the new five-story building and the nine-story clinic expansion.

The new building’s curved façade connects to the tower expansion by a skyway which is composed of a monumental compound curved, dual-cantilevered structural silicone-glazed cladding system.

Empirehouse provided both the aluminum panel and curtainwall systems which maximized the envelope product integration and efficiency of the building envelope installation.

Empirehouse selected the façade and functional components to integrate within the curtainwall system. This allowed for easy access to windows from the inside or the outside of the enclosure. Vapor barrier components were installed to ensure that the patient environment was free of water infiltration.
