Greenbuild 2013 Settles in Pennsylvania, Bringing New Glass Innovations

The Pennsylvania Convention Center in Philadelphia will go green November 20-22. Not literally, of course, but an anticipated 30,000 attendees and 900 exhibitors from the green building industry will gather there to do business. More than100 educational sessions are planned, including world-recognized speakers, LEED workshops, off-site educational sessions, and green building tours of local sites. This year’s speaker lineup includes a keynote by former Secretary of State Hillary Rodham Clinton and closing plenary speech by noted author and statistician Nate Silver.

The trade show floor will be the big draw for many. Here’s a sampling of those that will be there with some of their newest green glass and glazing developments.

curtainwall
Curtain Call – Booth #1927

Several new developments will be available from Kawneer Co. Inc. The company will bring its 1630 SS IR curtainwall to the show. Having undergone testing to hurricane and blast mitigation standards, the new curtainwall offers an additional line of defense against high winds, heavy rains and hurricanes, the company says.

The new series meets design pressure requirements on buildings in impact zones, larger span needs and ease of installation requirements with a 3-inch sightline, Kawneer reports. The company adds that the curtainwall has been tested to ASTM 1886 and ASTM 1996 standards, the TAS 201, 202 and 203 test protocols to meet Florida Building Code (FBC), and Miami-Dade’s Notice of Acceptance (NOA) criteria. The product has been tested for large- and small-missile impact and meets Level E (Enhanced Facilities) requirements, among other requirements.

The curtainwall is available in wet (silicone) glazed and dry glazed options, both of which have been tested up to 130 pounds-per-square-foot design load, and thermal cycling per AAMA 501.5 has been performed.

In addition, the company’s Traco division will also showcase its AA®5450 Series window addition to the OptiQ Ultra thermal window, now available in single and double-hung configurations, including a matching fixed option.

The AA5450 Series maintains thermal continuity, reduces thermal transmission and helps maintain interior comfort, the company says.

Thermal options on the AA5450 series window can be added or removed based on performance and cost requirements. A polyamide thermal break allows OptiQ Ultra Thermal windows to achieve higher thermal performance than the traditional style thermal breaks, according to the company, and performance is further enhanced by accommodating 1-inch double pane or 1-½-inch triple pane insulating glass. www.kawneer.com
