AIA Heads to Atlanta with the Latest Glass Developments

There are plenty of must-sees when visiting Atlanta: the World of Coke, Georgia Aquarium, and CNN Center, just to name a few. But if you’re visiting in May and architecture is your game, you’re likely in town for the American Institute of Architects National Convention. Set for May 14-16 at the Georgia World Congress Center, the event promises plenty of educational opportunities, as well as a packed trade show floor. Read about glass-related seminars on page 42 for more.

Companies representing the glass and glazing industry will also be on hand with their latest developments.

Exhibitors will showcase everything from coated glass and components to curtainwall and metals. Take a look at some of the products you’ll find at the show.


Booth #2545:
Glass For Outside and In

Guardian Industries will display several products, including its expanded SunGuard Spandrel HT offerings and its ShowerGuard low-iron float glass.

Designed for North American building façade spandrel applications, SunGuard Spandrel HT creates a seamless and aesthetically pleasing look that conceals interior views from the outside. Guardian uses a proprietary coating system for this new product; during heat treating, the coating bonds to the glass and is fused permanently to the surface.

This creates ceramic frit characteristics with increased uniformity from the precision application process, according to the company. SunGuard Spandrel HT is available in white, warm gray and black.

ShowerGuard is designed for all types of shower enclosures and was created to resist glass corrosion. According to Guardian, the glass reduces the greenish cast of standard float glass for enhanced clarity, allowing the design and color of showers and bathrooms to shine through. With its more neutral edge color, ShowerGuard low-iron is ideal for clear, frameless enclosures, in 10-mm and 12-mm thicknesses. 



Booth #851:
PPG’s Solar System

PPG Industries will display a range of its glass options, including its Solarban z75 glass, Optigray glass and Solarban 72 Starphire glass.

Solarban z75 is a solar control low-E glass, which features a neutral, cool-gray tint and offers architects and building owners a combination of visible light transmittance, solar control and glare control characteristics. In a standard 1-inch insulating glass unit (IGU), Solarban z75 glass has a visible light transmittance (VLT) of 48 percent and a solar heat gain coefficient (SHGC) of 0.24, resulting in a light-to-solar-gain (LSG) ratio of 2, according to PPG.

Optigray is an ultra-neutral, warm-light-gray glass designed to maximize light transmittance and clarity, and to work with Solarban coated, solar control, low-E glasses to enhance solar control performance. The glass is formulated to offer an extremely light-gray tint that eliminates the green naturally present in conventional clear glass formulations, according to the company.

Solarban 72 Starphire glass was designed for both clarity and solar control. According to PPG, in a 1-inch IGU, Solarban 72 Starphire glass has a VLT of 71 percent and a SHGC of 0.30, producing an LSG ratio of 2.38.
