AGC’S U4 Coating Delivers R5 Performance in an IGU
AGC Flat Glass North America in Alpharetta, Ga., has introduced U4 4th Surface Technology™, which it says allows double-glazed units to achieve the same levels of efficiency as costlier triple-glazed units.

The U4 4th Surface Technology system incorporates a patent-pending pyrolytic low-E hard coating that can be installed on the fourth surface of the insulating glass unit (IGU). This coating technology enables manufacturers to use two low-E coatings in one IGU, resulting in an R5-rated glass package in a double-glazed unit.

The company reports that adding U4 coating to a double-glazed IGU reduces the center of glass U-factor by as much as 20 percent compared to standard IGU configurations with one low-E coating. The U-factor reduction gained with the coating improves the whole window performance by 16 percent when compared to a standard glass package. With the addition of the new coating to the room-surface of the inner pane (surface #4), the window is able to reflect energy to the inside as well as to the outside. This reduction improves the overall insulating properties by as much as 15 to 20 percent over conventional IGUs.

Pilkington’s Solar-E™ is Now Available in More Colors
Pilkington in Toledo, Ohio, is expanding its architectural line of energy-efficient solar control low-E products. The Solar-E™ coating, with its low solar heat gain coefficients and low reflectivity, is now available on a palette of natural colors—Arctic blue, blue-green and grey—to complement Solar-E on clear and other lines of pyrolytic low-E products.

The Solar-E family of products provides a combination of aesthetics and performance values with the same benefits of the on-line hard coat technology. It can be bent, insulated, laminated and tempered, and edge deletion is not required. It also can have a ceramic or frit applied to the coated surface for spandrels or a silkscreen pattern can be applied for the vision lites. It has an unlimited shelf life, and will not oxidize or change color over time.


Clearwall™ Delivers Monolithic Look for Low-Rise Applications
To provide a monolithic look for low-rise applications, Kawneer Co. Inc. in Norcross, Ga., has introduced its Clearwall™ curtainwall. The four-sided toggle glazed (TG) system features a breakthrough glass retaining mechanism. The company says its new curtainwall is a cost-effective alternative to four-sided systems, and its unique toggle mechanism reduces installation labor, simplifies onsite logistics and enhances safety while providing superior aesthetics.

The toggle mechanically captures the inboard lite of the IGU and is designed to rotate in place and automatically lock when the fastener is installed. Each toggle captures an edge of adjacent lites, increasing the efficiency of installation. Screw spline construction and straight cuts without any notching simplifies fabrication. Clearwall curtainwall features two mullion depths for design flexibility.

Clearwall is offered in two other glazing options, each accommodating 1-inch insulating glass and using the toggle system. Options incorporate an attached interface to the glass with structural silicone or 3M™ VHB™ structural glazing tape.

DuPont™ Structural Safety Glass Interlayer Stands Guard
SentryGlas® ionoplast interlayers from Wilmington, Del.-based DuPont™ are designed to help create light, safe, strong glazing that stands up to greater loads and higher threat levels. The interlayer’s rigidity and toughness are well-suited to structural glass in applications such as floors, stairs, balcony rails and minimally-supported facades and canopies.

Up to 100 times stiffer and 5 times tougher than traditional PVB interlayers, SentryGlas® also is noted for clarity, edge durability and an ability to bring more natural daylight into larger spaces. The interlayers are available in a range of thicknesses.

Vanceva® Creates Color Options
The Vanceva® color system by Saflex®, a part of Solutia Inc. in St. Louis, gives architects and designers the ability to create more than 3,000 colors for architectural laminated safety glass. Glass fabricators can leverage the color system to reduce traditional lead times for custom colored glass simply by stocking nine layers of Vanceva PVB and combining them in up to four layer configurations to achieve the architect’s desired color.

Based on a CMYK color model, the Vanceva color system consists of pink, blue, yellow and grey interlayers in two light transmissions. In addition, Solutia publishes color forecasts each year for the Americas, Europe and Asia Pacific to assist fabricators and designers in understanding color trends around the world.
