Guardian Launches Glass Visualizer
Guardian Industries has introduced the InGlass Visualizer, a new, online tool that enables interior designers and architects to marry interior glass products with applications to see how integrating different types of glass can transform the visual impact of the space. The InGlass Visualizer is the newest component of Guardian InGlass, created to bring together the company’s entire advanced interior glass product line. “We want designers to stretch their imaginations and understand the flexibility of using glass,” says Diane Turnwall, market segment director of interiors. “Our goal is to help designers and architects express their creativity in a way that meshes with our digital society, and the InGlass Visualizer gives them another great tool to do so.” www.guardianinglass.com

Glasswerks Provide Privacy Glass
Los Angeles-based Glasswerks Inc. has begun to work with Sunnyvale, Calif.-based Citala US Inc. to offer customized privacy glass.

Glasswerks now will offer Citala’s Onyx-based smart films in its Voltage Glass products, which will allow users to change the translucency of a window from opaque to transparent with the flip of a switch. “This partnership allows Glasswerks to move into a growing segment of the glass marketplace,” says James Harris, Citala’s vice president of sales and marketing.

Go Frameless— with an Impact
Faour Glass Technologies of Tampa, Fla., offers a new frameless hurricane impact-resistant window system called the Slimpact. The system was developed in close collaboration with DuPont and the company says it has been tested to ASTM E 1886, ASTM E 1996 and AAMA 501- 05 (see related story on page 26). The patent-pending system can be used in both commercial and residential applications in hurricane-prone areas, according to the company. yyä

Spider Fittings in Range of Specs
Rinox Kaufmann Ltd. offers a variety of spider fittings designed to adhere to various engineering specifications. The spider fittings are designed to provide durability along with a stylish design for applications such as glass walls, glass canopies and frameless glass balustrades.
The fittings are available in a variety of sizes, shapes, color, thickness and more.

The Latest in Storage
The Glass Racking Co. has developed a tooth-based storage system for single lites, insulating glass units and window sections and doors. Company officials say the system provides a V-shape for securing the items, so that items with varying widths can be stored alongside each other in the same system, and items are separated with no hard or damaging surfaces. The system also allows individual items to be accessed without sorting through the others, speeding the process and reducing damage and rework.

Swap Safety Eyewear Answers Fog
The new Swap line from Gateway Safety is a unique glasses-to-goggle eyewear solution designed to fight fog. The glasses are equipped with a foam lining that surrounds the one-piece lens to block dust and debris. The lining also includes venting channels that help reduce hot air buildup. The Swap line also features the company’s high-quality anti-fog formula on both sides of the lens. In addition, the glasses can be changed easily into goggles by swapping the temples for a head strap with a simple snap. Both the temples and head strap are included.

Kawneer Adds Sunshade Option for 1600UT
Kawneer Co. Inc., an Alcoa business, recently expanded its Versoleil SunShade platform to fit its 1600UT (Ultra Thermal) System 1 curtainwall. This addition offers a fully pre-engineered and tested solution for applying both Versoleil Sunshade Outrigger and Single Blade Systems to double (1-inch) and triple-glazed (1 3/4-inch) infill versions of 1600UT System 1 curtainwall, according to the company. The Versoleil SunShade is designed to withstand combined wind, snow and dead loads, minimize direct sunlight and reduce solar heat gain. Company officials say it also can contribute to Leadership in Energy and Environmental Design (LEED) certification.

Test IG Units for Failure
When replacing failed insulating glass units (IGUs), a concern to glaziers and their customers is how many more units may soon fail. On-site testing can be done inside or outdoors at any place on the glass to find the near-failure IGUs. Jim Spetz Consulting has developed handheld IGU testers that weigh less than a pound and single suction cup testers that weigh three pounds. According to information provided by the company, these testers are one-third the weight and a quarter of the cost of D-100 ASTM E-576 testers. The new testers come with instructions on their use and how to perform the tests, which are in the process of becoming an ASTM procedure. Jim Spetz explains that sealed IGUs have desiccated air space and the relative humidity in the air space is less than 0.01 percent. If the seal is breached the desiccant becomes fully loaded with moisture vapor and the relative humidity in the air space is 100 percent. The test is designed to get the 1-inch diameter area of the glass very cold. If the air space is dry, no moisture condenses inside the unit at the very cold spot. If there is a seal problem, a combination of ice crystals and water condenses inside the unit at the cold spot. Commercial IGUs made with ¼-inch thick glass require a 5-minute test time. When using three suction cup-attached testers and a handheld tester on the fourth unit, users can average eight to ten sets of four units in an hour, according to Spetz. Test times should be doubled if the glass is laminated, Spetz adds.

“Heat Sheet” Shows Glass Performance
EDTM Inc. now offers the “Heat-Sheet” temperature demonstration card, which is designed to provide a simple, economical demonstration of a glass product’s energy performance. The Heat Sheet temperature demonstration card (HS2050) vibrantly changes color when it encounters heat. It can be used in combination with the company’s heat lamp (HL1040) to illustrate heat passing through a glass sample. As heat passes through an inefficient piece of glass, the sheet displays a dynamic color change. In addition, it demonstrates all three kinds of heat transfer—radiant, conduction and convection; is simple to use and understand; and measures approximately 6 inches by 4 inches tall.
