glass is it
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.
It’s a Bird …
A line of bird-safe, low-E coated, acid-etched glass products is available from Walker Glass in conjunction with PPG Industries. The glass utilizes both Walker’s AviProtek pattern and PPG’s Solarban glass.
According to Walker, the glass comes with AviProtek acid-etched stock or custom patterns on surface one, combined with the high-performance low-E coatings, Solarban 60, Solarban 67 or Solarban 70xl glasses from PPG on surface two.
Cladding Goes High-Tech
Alcoa Architectural Products now offers Reynobond NC coil-coated double-sheet aluminum panels, a new cladding option for façades with high technical, visual and environmental requirements. Engineered to deliver the flatness and stiffness of traditional Reynobond aluminum composite material (ACM) with the dent resistance and recyclability of sheet metal, NC double-sheet panels come in sizes up to 62 inches wide and 20 feet long, facilitating the production of 60-inch modules.
The new double-sheet aluminum panels are offered in a full range of coil-coated paint finishes, including high-performing Colorweld 500 finishes, trompe l’oeil Design Line finishes, PrismFX color-shifting finishes and CID/Retail program colors.
Terra Cotta Style
Linetec will feature its expanded palette of texture finish colors, created to mimic the look and feel of natural terra cotta. The finish utilizes a 70-percent PVDF resin-based coating to achieve a high level of performance in an exterior environment and a texture additive to help replicate the natural feel of terra cotta.
Sage Electrochromics will feature its SageGlass, an advanced dynamic glass designed to electronically tint or clear to optimize daylight and improve the human experience in buildings, according to the company. SageGlass is designed to manage the sunlight and heat that enter a building, reducing energy consumption while improving people’s comfort and well-being. It can reduce a building’s cooling load by 20 percent and HVAC requirements up to 30 percent. With SageGlass users can control sunlight and block glare without shades or blinds while maintaining the view and connection to the outdoors.
YKK AP America Inc. added the 35HL/50HL impact-resistant entrances to its Protek product line. The 35HL/50HL medium- and wide-stile impact-resistant doors were designed for applications where hurricane impact performance and cost are priorities.
The HL series also was developed to provide sizes, options and delivery required for fast food and low-rise retail projects. The 35HL/50HL impact-resistant entrances were tested to meet large and small missile impacts up to 50 PSF, according to the company. The doors are also equipped with low-maintenance single-point hook locks and meet the stringent standards for Florida’s High Velocity Hurricane Zone, Miami Dade and Broward counties. Each door features the YKK AP VersaJamb design, a reinforced tubular door frame that allows for sidelite glazing without shear clips while maintaining the structural integrity of transom frames.
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.
Curtainwall and Storefronts with Custom Fabrication
Petersen Aluminum provides custom fabrication for curtainwall and storefront applications. The company utilizes advanced shearing and bending equipment to produce a wide range of custom architectural components. The manufacturer’s anodizing capabilities allow for clear, as well as a complete range of bronze and black shades, while maintaining an extremely tight color range, according to the company.
Seal It Now
Dow Corning will feature both its 121 structural glazing sealant and HPI-1000 building insulation blanket.
The 121 structural glazing sealant was designed for assembly, installation or repair of structurally glazed glass and other substrates. Featuring easy-to-use dispensing, the 121 structural glazing sealant offers a 1-to-1 (“121”) mix ratio and is supplied in a two-part cartridge, complete with a static mixer. The sealant is suitable for both on-site and in-shop structural glazing. It offers a 24-hour cure rate and is backed with an available 20-year structural adhesion limited warranty.
The company’s thin-profile HPI-1000 building insulation blanket was created to provide thermal performance to combat thermal bridging losses in space-limited, hard-to-insulate areas. The new, thin, flexible insulation material uses advanced silicon-based aerogel technology to deliver thermal resistance.

Keralite’s True Colors
Vetrotech Saint-Gobain has added a new, innovative glass ceramic to its Keralite product line. Keralite Select combines patent-pending surface polishing technology with advanced composition to create a sharp, accurate color-viewing glass ceramic.
Keralite Select has a color-rendering index of 97.1 (out of 100). It also has a low haze value of 0.5 percent and bears no cloudy appearance even in variable lighting conditions, according to the company.
Manufactured in both 3⁄16-inch (Keralite Select F) and 5⁄16-inch (Keralite Select L) thicknesses, Keralite Select is recommended for larger glass sizes in impact-rated areas where superior clarity and sharpness is desired. The glass, which installs into standard fire-rated frames and doors, comes in 20-, 45-, 60-, 90- and 180-minute fire ratings.
