"The spans at first level were very high: 23 feet to the first support point. That's why the frames are so heavy, because you have so much internal steel to carry those loads." — Robert M. Rushing, Pre-construction Department manager, Architectural Aluminum Techniques, Orlando, Fla.

The basics: Amway Arena in Orlando, Fla., the new home of the Orlando Magic, was completed in 2010 and features large expanses of protective, impact-resistant curtain wall. "The glass in the building is the most dominant architectural feature," said Thomas Chatmon, executive director of the Downtown Orlando Development Board. "The specifications allow that the glass reacts in a predictable manner when the weather is adverse. That's very important."

The players: Architect, HOK Sport Inc., Kansas City, Mo.; general contractor, Hunt Construction Group, regional project office, Orlando, Fla.; glass fabricator, Viracon, Owatonna, Minn.; glazing system supplier, YKK AP, Austell, Ga.; glazing contractor, Architectural Aluminum Techniques, Orlando, Fla.

The glass and systems: About 64,000 square feet of YKK AP YHC 300OG impact curtain wall system. The overall size of the system is 3 inches by 7 13/16 inches, and 3 inches by 10 1/2 inches. The exterior doors for the project are YKK AP 35H Medium Stile Impact Doors — 70 exterior door leafs and 22 interior door leafs. The basic glass makeup is 1 5/16-inch insulating glass with a laminated inboard lite. Multiple makeups include: VE1-2M low-E coating on clear glass; VE5-2M low-E coating on Versalux Blue; VE1-2M on clear with a high opacity white opacifier on the inboard lite; VE1-2M on clear with a silk screen white dot pattern; some accent glass with the ½-inch air space containing a blue honey-comb material by Panelite, New York. Door lites were 9/16-inch laminated.
