AIA Unveils the Latest Glass Developments in Atlanta

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. Held May 14-16 at the Georgia World Congress Center, the event featured plenty of educational opportunities, as well as a packed trade show floor.

Companies representing the glass and glazing industry featured their latest developments. Exhibitors showcased everything from coated glass and components to curtainwall and metals. Take a look at some of the products at the show.

Booth #2545:
Glass For Outside and In

Guardian Industries features 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.

curtainwall and windows

Booth #2237
Take the Metro

FG 501T window wall, the first in Kawneer’s MetroView window wall series, offers a slab-to-slab aluminum frame design with an integrated edge to replicate the appearance of a true curtainwall. Described as sleek, efficient and versatile, MetroView FG 501T window wall is ideal for mid-rise commercial and multi-family housing projects.

The window wall’s 2-1/4-inch sightline and standard 5-inch depth make it easy to achieve stylish urban aesthetics, according to the company. To accentuate skyline views, balcony doors seamlessly integrate into the system. It features shallow horizontal cross members with the glass set to the front of the system to maximize the interior space.

Screw spline fabrication and joinery means easy construction and low installation costs, while simple two-piece receptors provide efficient installation, according to Kawneer. Corner members for either 90- or 135-degree applications increase design flexibility, and optional expansion vertical mullions help architects and designers achieve a customized appearance.

Thermal performance is enhanced with the IsoLock thermal break, and the sturdy aluminum construction not only provides structural integrity, but also ensures that the system will never rot, warp or buckle from moisture or weather exposure, according to the company. Additionally, the window wall is fully tested to industry standards including hurricane resistance large missile impact requirements of ASTM E1886 and ASTM E1996.

Booth #851:
PPG’s Solar System

PPG Industries displays 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.

Booth #3237:
New Spaces, New Faces

The JEB 3SEAL insulating glass spacer system and the Renovate by Berkowitz (Renovate) window/curtainwall retrofitting system displayed in the J.E. Berkowitz LP booth.

Designed for commercial glazing, the JEB 3SEAL insulating glass spacer system is made from structural thermoset silicone with integral 3A desiccant together with a triple-seal design consisting of a pre-applied acrylic adhesive for spacer-to-glass bonding, a hot-applied captive polyisobutylene primary seal, and a two-part structural silicone secondary seal.

The Renovate system was designed as a cost-effective solution for updating a building’s windows or curtainwall. Intended for commercial buildings typically built before the 1970s, the Renovate system is a factory-made, double-pane insulating glass unit (IGU) installed to the interior surface of an existing single-pane window. Compared to a traditional window replacement, the Renovate system offers similar benefits, but costs about 50 percent less and can be installed two to three times faster, according to the company. The Renovate system is available in three glass configurations and can offer solar heat gain coefficients as low as 0.27, winter U-values as low as 0.15 and R-values up to 6.67.

Booth #629:
Form a Strong Bond
As architects are increasingly turning to glass for curtainwall construction, such as transparent structural glazing walls, single or double-glazed, or even double-skin façades, it can be a challenge to balance aesthetic appeal and energy efficiency. This requires adhesion between the components and highly elastic, weatherproof seals.
Sika will feature a variety of options that can help. These include engineered structural adhesives and sealants to meet these demands and guarantee peak performance, according to the company. Sika supplies a wide range of innovative facade products with highly specific properties to meet the specific application. These include structural glazing and insulating glass secondary seals, as well as weather seals.

Energy Options from AGC

Energy Select 28 is one of the latest developments from AGC Glass Co. North America. The glass is a high-performance, triple-silver on a clear substrate with a visible light transmittance of 62 percent. Also new is the Energy Select 20, triple-silver available on the company’s most popular tinted substrates. These include pure bronze, pure grey, meadow green and forest green achieving solar heat gain coefficients as low as .20 and light-to-solar gain ratios in the range of 1.58 to 2.02, depending on the tinted substrate selected.

These new glass products offer maximum solar control and high visible light transmittance. They were designed for commercial buildings where cooling costs are of primary concern, and the energy code requirements are focused on the solar heat gain coefficient, according to AGC. 

Energy Select 31 is another new high-performing coated glass product, which has a slightly blue hue designed for commercial building applications.  It was developed to provide optimum performance in both warm- and cold-weather regions, with a visible light transmittance of 62 percent and solar heat gain coefficient of 0.31.
