GANA Members Spotlight Their Most Memorable Products and Projects

Memorable Projects

Downtown Glass Completes World-Class Project
Oklahoma City-based Downtown Glass Inc. recently completed the Integris Cancer Institute of Oklahoma, a comprehensive and world-class cancer treatment center. The glazing contractor says the variety of glass configurations specified by HKS Architects contributed to the stunning visual appeal of the completed project. Vitro America’s facility in Farmers Branch, Texas, fabricated the glass for the project, which is made up of 1-inch Energy Glaze™ insulating glass units. The units are comprised of PPG’s Z50/clear, Z50/OpaciSpan™ black ceramic frit, Vistacool Azuria/Solarban 60 and Z50/Vitro Pavia™ acid-etched glass. Vistawall supplied the metal.

LCG Creates a Flagship Feel for OC Tanner
The OC Tanner Flagship store is a major renovation of the Salt Lake City old public library. Salt Lake City-based LCG Facades was asked to design, engineer, facilitate and install the point-supported insulating glass wall with first surface ceramic frit, the stainless steel surround and bollards. The stainless steel surround was designed to weep rain water internally and, the glazing contractor points out, has no exposed caulk joints.

On the interior, LCG furnished and installed custom stainless steel metals, all-glass doors and decorative elevator mirrors. The curved stairs also were part of the subcontractor’s scope. LCG reports that it turned to Soheil Mosun Ltd. to design, engineer and install the stainless steel handrail, ½-inch tempered curved glass and the structural steel steps.


EFCO Assists in Creating an Educational Landmark
Morgan State University’s new library features a 3-story atrium-style wall of windows. EFCO System 5600 curtainwall was integral to achieving the scope of this striking instructional space. Available in a wide range of mullion and face cover depths, this system features roll-on horizontals and concealed fasteners for uninterrupted sightlines.

Behind the library’s glass façade, student reading areas are placed against the glass and connect to the rest of the building via bridges that penetrate a wood wall punctuated with windows.


Wheaton & Sprague Chosen for Case’s Complex Curtainwall
Wheaton & Sprague Engineering (WSE) in Stow, Ohio, is completing the system design, structural engineering, detailing, thermal analysis and fabrication drawing process for the custom cladding systems for Case Medical Center at the University Hospital in Cleveland, currently under construction.

The 375,000-square-foot facility by Cannon Design features 92,000 square feet of custom unitized high-performance curtainwall, custom slope-wall, custom windows and standard storefront. It also includes 44,000 square feet of composite panels and 4,000 square feet of louvers. Unitwall and slopewall are both custom systems designed by WSE to meet the project’s rigid requirements. The panel system is a rain-screen system supported by a light gage stud wall anchored to the building. Dominant features include a transition to a slope wall on one elevation; members curved in elevation on another; a “bowed” wall feature on another; and transitions between curtainwall and panel systems.

The Glass Association of North America (GANA) released the 50th anniversary edition of its Glazing Manual this year, a momentous landmark for an association that has changed and grown significantly in that time. As the association has changed, so too have its members, which includes glass retailers, distributors and manufacturers as well as glazing contractors, consultants and others related to the field. These diverse groups have each submitted to USGlass information on some of their landmarks. Some of these “most memorable” products and projects are new, some are industry standbys, but all are worth a second, or third, glance. The results are below.


SCHOTT PYRAN® Platinum Provides Transparent Safety
PYRAN® Platinum glass-ceramics are environmentally friendly fire-rated glass-ceramics, according to SCHOTT of Elmsford, N.Y. These products are produced without the use of hazardous heavy metals and are fire-rated up to 90 minutes (180 minutes in doors), pass the hose stream test and are UL-classified. The glass-ceramic products are transparent, wireless and able to withstand thermal shock. The company reports that they are suitable for use with standard fire-rated frames with the same rating.

For fire-rated and impact-safety locations, SCHOTT offers PYRAN® Platinum F, which has surface applied film, and PYRAN® Platinum L, which is a laminated glass-ceramic.


Solarban Lets in Light, Keeps Out Heat
Pittsburgh-based PPG’s transparent Solarban 70XL glass offers a strong combination of visible light transmittance and solar control. With a SHGC of 0.27 and VLT of 64 percent in a 1-inch insulating glass unit, Solarban 70XL glass produces an LSG ratio of 2.37.

The manufacturer says that independent energy analysis has shown that substituting Solarban 70XL glass for dual-pane tinted glass reduces initial HVAC equipment costs by as much as $125,000 in a prototypical window-walled, eight-story office building and cuts annual cooling costs by as much as 7 percent.

HPP™ Coating Protects Warm-Light®
Warm-Light® warm edge spacer by AZON USA INC. in Kalamazoo, Mich., is now available in a high-performance polymer (HPP) coating. Three new HPP™ colors are now offered; Silver Matte, Stone and Monumental Bronze.

The coating inhibits oxidation on the aluminum surface. The aluminum in Warm-Light is comprised of 78-percent recycled content with the material advantage of complete recyclability at the end-of-use.


DORMOTION Cushions Sliding Glass Door Movement
The new DORMOTION system from DORMA Glas in Millersville, Md., provides assisted closing and cushioning of interior glass doors. When integrated into the AGILE 150 sliding door system, the DORMOTION hardware smoothly draws the sliding panel to its end position as it travels on the roller assembly, much like the spring-aided action of kitchen drawers. DORMOTION system also prevents harsh end-stops that could damage doors or hardware. An end-stop function eliminates uncontrolled fallback and incomplete closure.

The hardware is suitable for single or double doors.


Tem-Pace Molds Its Art
Sculpturlite, the Tem-Pace Inc. brand for the Niles, Mich.-based company’s formed glass product, is proving to be popular in the decorative glass entry door market, the company says. Fashioned with distinctive characteristics, the molded glass allows the consumer to touch and feel the images created.

Among the product’s most popular designs are that of a lighthouse, followed by the image of a leafless oak tree, while numerous other designs also are available.

SteelBuilt Stands Strong
Utilizing the strength of steel, the SteelBuilt Curtainwall Infinity™ System from Technical Glass Products in Snoqualmie, Wash., allows architects and designers to use larger areas of glass, smaller frame profiles and wider free-spans than is possible with traditional curtainwall assemblies. The Infinity Series opens up a new realm of design possibilities by offering back mullions of virtually any profile, including I-, T-, U- and L-shapes, and can use as a back mullion almost any type of framing member, including stainless steel and glulam beams. This flexibility allows the system to be used in a variety of designs, from high-end urban storefronts to facilities that incorporate wood throughout.

ISOPORT Enhances Views and Efficiency
Norcross, Ga.-based Kawneer’s AA®3350 ISOPORT® Window was designed to enhance the views and energy efficiency of any application. Available in fixed, single- or double-hung with a polyamide thermal break design and factory glazing, the company says its versatile window achieves thermal performance at a competitive price. The uniquely shaped polyamide thermal break maintains continuity of the thermal break throughout the window frame and sash, enhancing the window’s performance. AA®3350 ISOPORT® Window is factory assembled and glazed.

Vesuvius Unveils New Tempering Roll
Vesuvius has launched an environmentally—and ergonomically—friendly Smartly Driven® all-mechanical end cap attachment system.

This product eliminates the need for resin bond adhesives for end cap attachment. It is capable of withstanding demanding torque operating conditions.

The Smartly Driven® end cap can withstand operating temperatures up to a maximum of 350° C, compared to 150° C with the resin bonded design.
