Horizon Glass fabricated and installed the custom windows and Curtain Wall scope for the renovation of the Denver Art Museum’s Martin Building, the comprehensive restoration of Gio Ponti’s iconic 1971 tower—the only completed building in North America by the renowned Italian
modernist. Designed by Machado Silvetti with Fentress Architects as architect of record and delivered by Saunders Construction. The project fully renovated all eight levels of the two-towered, ~210,000-square-foot landmark for its 50th anniversary, adding more than 33,000 square feet of
new gallery and public space, realizing Ponti’s original vision for seventh-floor terraces and city views, introducing new skylights, and revitalizing the more than one million reflective glass tiles that clad the building’s famous façade.

Horizon’s scope encompassed the building’s 217 replacement windows—including 102 custom shapes anddimensions—along with curtain wall and a complex reworking of the museum’s signature entrance: Horizon removed the existing entrance tube, then reinstalled and modified it to accept a new custom all-glass entrance. The work supported the building’s restored thermal and
moisture integrity while delivering the daylight and refined detailing central to the renovation of one of Denver’s most beloved cultural landmarks.
