Great Glazing: Clyfford Still Museum

The basics: The $30 million Clyfford Still Museum, a gift from the artist's estate to the city and county of Denver, houses a collection of more than 90 percent of Still's total work. The 30,000-square-foot building is located on a prime site in Denver's Civic Center Cultural Complex, located directly west of Daniel Liebeskind's iconic Denver Art Museum building. Architects chose glass products that would control the daylight's intensity, preventing damage to the artwork.

The players: Architect, Allied Works Architecture; general contractor, Saunders Construction Inc.; glass manufacturer, PPG Industries; glass fabricator, Oldcastle BuildingEnvelope; skylight supplier, Skyline Sky-Lites LLC; glazing contractor, Metropolitan Glass Inc.
