28 USGlass, Metal & Glazing | April 2011 www.usglassmag.com

As glass companies pro-vide solutions to more prob-lems, the requirements just

keep getting tougher. “As technology advances, architects

are realizing they don’t have to compro-mise on the design front in order tomeet sustainability and performancegoals,” says Devin Bowman, nationalsales manager for Technical Glass Prod-ucts (TGP). As an example Bowmancites the fire-rated glazing industry. “Ar-chitects want all-encompassing fire-rated solutions. At TGP, this has led toan increased demand for sleek fire-rated frames and ultra-clear glazing,which better integrate with existing de-signs. It’s also led to an up-tick in ap-plications that can pull light in fromadjacent places and open up interiors,like glass firewalls and fire-rated glassfloor systems,” he says.Fire protection, sleek design, lots of

daylighting? No problem. How aboutexcellent performance benefits, struc-tural stability, throw in some blast orimpact resistance and that can go in ahistoric retrofit too, right? Talk about atall order. “This is becoming a much more

common trend in project specifica-tions,” says Michael Castleberry, archi-tectural support for BoydAluminum inSpringfield, Mo. “Currently we all seethe standard qualifications for air, waterand structural performance, along withthe NFRC window thermal perform-ance; lately we have seen a large multi-functional cross-reference for blast andimpact requirements on fenestrationproducts within the same project.”Castleberry adds, “I don’t see this trend

reverting back, as in this market projectowners, architects and customers arelooking to find products that performacross a wide range of market needs.”

It seems that now,more than ever, prod-

uct quality is key. “We feel quality is playing a bigger

role in the future,” Juha Liettyä, seniorvice president of Glaston Services, com-mented during glasstec in October 2010(see December 2010 USGlass, page 64).Geys Gomez with Bridgestone com-

While we all know architects want to set the trends, not follow them,

you just know that at times you’ll see certain products moving more

quickly off the shelf (so to speak, for you custom types). That’s why

we asked readers of the USGNN.com™ daily e-newsletter and members of the

USGlass online community about the trends they’re seeing—and starting—for

architectural glass. Whether you love them or hate them, these are the trends

you can expect to see at the annual AIA Convention (see page 52), industry

trade shows and your next jobsite.

In some cases glass is being expectedto do a little of everything. Still, othersuppliers says they’re seeing a lot moreinterest in glass that does little but lookfantastic. “Design professionals keep finding

new and interesting ways to use glazing.One emerging trend is to use the uniquedepth and shape of specialty glazing ma-terials to create visual focal points,” saysJeff Razwick, vice president of businessdevelopment for TGP. Razwick offers thechannel glass his company distributes asan example. “It can diffuse light, createtight-curving façades, make artisticstatements with various colors and sur-face patterns, and add drama whenbacklit. We’ve even seen it used as thebackdrop of a waterfall.”John Krajewski, sales representative

for Walker Glass, sees opaque acid-etchglass as an example of this hot trend.“All of a sudden it’s been catching onlike crazy,” he says.

mented at that same event,“For added-value [products] the customer is ex-pecting quality because they are payingtop dollar.” That could well be the impetus of this

latest trend. As contractors and otherslook for the lowest bidder, glass productproviders have replied by improving thequality of their products over their low-cost competitors. Machinery manufac-turers are following that same trend withnew offerings that help fabricators en-sure their quality is top of the line. “The demand of the quality glass is

becoming a must as the architects andengineers today are requiring excellentsurface quality and aesthetics of theglass in the buildings they are design-ing. It is very obvious that this trendwill fast explore to all market places,even to those now developing,” Liettyätells USGlass. He adds, “New glass typesare introduced all the time and the en-ergy regulations will lead to tougherquality requirements in the future.” Ac-cording to Liettyä, fabricators able toproduce good quality glass will differ-entiate themselves from others. Bruce Lang, vice president of mar-

keting and business development forSouthwall Technologies, adds, “Manu-facturers that go beyond these mini-mum requirements have a realopportunity to use quality, rather thansimply price, as a competitive differen-tiator. The automotive industry learnedthis long ago and is well ahead of thewindow industry in terms of adoptingcontinuous improvement and totalquality management (TQM) systemsthat focus on serving customers andtransforming front-line workers intosystemic problem solving teams. Theresults are an improved reputation withfewer defects and replacements, lowertotal costs and higher employee morale.Many of the more visionary glass andwindow manufacturers have used therecent downturn in the automotive in-dustry as an opportunity to hire someof this TQM expertise.”

3Looking AtgLAss, notthrough it









It didn’t start at glasstec 2010 (see De-cember 2010 USGlass, page 64) but theshow’s display of a record 59- by 11-footinsulating glass unit certainly got peopletalking. Then earlier this year at BAU, at-tendees saw seele’s self-supporting IGmeasuring nearly 20 feet long, and capa-ble of sizes up to 39 feet (see March 2011USGlass, page 54). It’s human nature tothink that if something is good then moremust be better, but this certainly isn’tmaking the glass professional’s job anyeasier. Not just the installation of these be-hemoths but explaining the challengesthat come with energy performance. Butthere are lots of reasons behind the grow-ing sizes of these units. “We have been seeing extrusion die

size design increasing in curtainwallprojects over the past several years.Thelarger die designs have been driven bybomb-blast mitigation, hurricane pro-tection, tightened building codes andthe increasing need for natural day-lighting in LEED projects,” says BrentSlaton, national sales coordinator forKeymark Corp. in Fonda, N.Y.

“Blast is fueling themarket,” commentedCastleberry during anindustry event last year

(see November 2010 USGlass, page 44),and his mind hasn’t changed since then. “I do believe that the blast-resistant

products and blast-resistant buildingdesigns are still fueling the market.Westill see a high demand for pre-biddingdesign assistance, specification writing,along with quote requests,” he says.“Thedifference in the last six to nine monthsis that more of our customer base (in-stallers and general contractors) are get-ting in the market, and where we usedto see one or two requests for pricing, weare now seeing anywhere from five toeight requests for the same project.” That’s where the work is, after all. “Our estimating level on blast and De-

partment of Defense (DOD) projects isincreasing exponentially because of thepropensity of government and public

funding,” agrees Dave Hewitt, director ofsales and marketing for EFCO Corp.”Castleberry adds, “This market seg-

ment has truly become a very compet-itive component of the fenestrationindustry. If a company is not currentlykeeping up with the evolving protocols(such as UFC, GSA, ASTM & AAMA),actively reading and understanding de-tailed project specifications, or makingsure that bid packages qualify exactlywhat has been priced, it could prove tobe a very costly market segment also.”Hewitt says that’s what helps to set his

company apart. “If you’re a business likeours that’s heavy on the front end as faras engineering services and reps in thefield that have a lot of the engineeringtools required, it helps us because it dif-ferentiates us from companies that don’thave a lot of those assets or can’t affordthose assets,” he says. He adds of thismarket, “It presents a lot of challengesand opportunities.”


“I think [architects] are discoveringthat acid-etch glass offers creativityaway from your typical clear glass. Itoffers the interior light opalescence. Itgives you light harvesting. Whenproperly backlit it gives you a ‘lanterneffect.’ … They’re also using it forspandrel.”

He cites a hospital where the com-pany’s acid-etch glass in blue was recentlyused as a spandrel “because it comple-ments the blue exterior glass without cre-ating the opaque banding line spandrelhas. It blends in better as a spandrel andit still gives you obscurity of the regularopacifiers,” Krajewski says.

Chuck Knickerbockersees two reasons moti-vating more architects

to call his colleagues at TGP for thecompany’s steel-framed curtainwalls,as opposed to conventional aluminumframing: performance and cost. AsKnickerbocker explains, steel providesbetter thermal performance since itdoesn’t conduct or radiate heat the wayaluminum does. In addition, steel is cheaper to

produce; there’s “less embedded en-ergy in turning iron ore into steelthan there is in mining, refining andthen extruding aluminum profiles,”he explains.According to the U.S. Bureau of

Labor Statistics, steel mill products hada producer price index of 159.9 in Jan-uary, up 2 percent since December2010. Aluminum mill shapes mean-while had an index of 182.3 that in-creased 1 percent between Decemberand January. On the other hand, Hewitt says, “It’s

really hybrids. He explains that beinga Pella Co. subsidiary gives EFCO ac-cess to “several pultrusion presseswhere we pultrude material that is re-placing aluminum.” On curtainwallsystems, EFCO offers a pultrudedpressure plate, Duracast®, that he sayshas “gotten a huge reception from ar-chitects and owners in the market-


Guy Charpentier,marketing managerfor Bonnell Aluminum in Newnan, Ga.,offers his assessment based on the cus-tomers and markets Bonnell serves. “Al-though the overall demand for aluminumextrusions has been impacted by thedownturn in the nonresidential buildingand construction, we continue to enter-tain a growing demand for larger profilesrequiring critical surface finish.”

place, because it increases your con-densation resistance factor.” That’sbeen touted lately as a big considera-tion especially for new hospital con-struction, Hewitt says.

“And,” Hewitt adds, “it increasesyour U-factor and thermal numbersdramatically … We have the perform-ance values in the metal to handle

large sizes and large windloads, [but]put with the components and technol-ogy we’re using internally in other ma-terials than aluminum, we’re able toget some very good thermal numbersfor U-factors.”

Regardless, it sounds like additionalmaterials are edging into aluminum’straditional turf.

“We have been seeing alot of call for spider clamp systems herein the Metro New York City area,” sharesRobin Selesky Smith, operations man-ager for ATM Mirror & Glass inBuchanan, N.Y.

Turns out that’s not a regional thing. “There has been a significant increase

in spider clamp fittings over the past fewyears,” agrees Mike Kushner, vice presi-dent of sales for TACO Metals Inc. inMiami. “Architects are specifying spiderclamps and fixed point fastener systemsfor glass façades, canopies and railings.These products have been very popularin Europe for many years and have finally

Today no discussion of glass, andits wonderful ability to let in naturaldaylighting, is complete without a dis-cussion of how to manage all of thatbright light coming into the building.

“Architectural interest in sun-shades, principally driven by energyconscious building design, has beenon the rise for the past three to fouryears. While the aesthetic element ofsunshades is still important to an ar-chitect, the demand for better per-forming sunshades, which integrateseamlessly into curtainwall systems,

gained acceptance in the U.S. as moretesting and engineering data has beenmade available to support their use.”

Andrew Chatfield, director of architec-tural glass systems for The Wagner Cos.,also sees “more and more people inter-ested” in spider systems. He notes,“There’s obviously some reticence in themarketplace always to use spiders be-

cause it’s technology that’s still relativelynew to the market, though [people] havebeen doing it up here in the Northeast fora long time.” The concern, Chatfield says,comes with the exactness required. “Youhave to put the holes in the right place,you’ve got to drill the holes exactly as theyshould be and there’s no room for error,there’s no or very little adjustment.”

Chris Dolan, director of commercialglass marketing, Guardian Industries, of-fers an explanation for this “growing trendin the commercial glass arena” towardpoint-supported glass. “Architects oftenlook for additional ways to make buildingsmore transparent. One way to accomplishthis is by using point-supported glazings.”

Dolan adds, “Because they are made upof more glass and decorative hardware,these buildings allow for improved trans-parency and offer additional architecturalopportunities in the detailing of thebolted connections. Increasingly popularin Europe, these exterior systems havecontinued to make inroads into commer-cial building design in the United States.”

Chatfield agrees that these systemsare garnering interest that matches theincreasing interest in daylighting. “As Ialways say, you sell light. Basically you’rebringing the light from the outside ofthe building to the inside of the build-ing with minimal obstruction.”

Alongside the undeniable push to-ward energy-efficient glass, Chatfieldsays he now is starting to get questionsfrom customers as to how they can im-prove the efficiency of the spider wall byincluding an IG unit … see Trend #1 …

is increasing,” says Jot Chahal, prod-uct manager of curtainwall, sun con-trol and BIPV for Kawneer NorthAmerica.

No kidding. What sunshades areable to do now—besides, obviously,providing shade—is getting morecomplex. For example, Kawneer’s Ver-soleil sunshade can be adjusted by 5degree increments, allowing it to beused in applications across the coun-try. Boyd Aluminum offers a sun-shade attached to an operablewindow. Companies such as Doralcoand Kawneer offer sunshades inte-grated with solar panels.

“Bottom line,” Chahal continues, “isthat sunshades are no longer consid-ered an add-on to the building façadebut have matured into a complete prod-uct line, with outrigger and single bladeconfigurations, horizontal and verticalorientations, and a plethora of blade de-signs, to name a few.”

We’ve been hearing aboutdynamic glazing—which can

turn glass from transparent to opaqueand back again following some sort ofstimulus, be it electrical or sunlight—foryears now as the next big trend.

“I’m not sure the product is com-pletely there yet, but it is a trend with aworthwhile goal,” comments John S.Baxter of Best Solar Glass Consultantsin Perrysburg, Ohio.

But one might say that dynamic glaz-ing manufacturers are becoming moreactive themselves. SAGE Elec-trochromics is constructing a new facil-ity that will allow it to mass-produce itsdynamic glazing product, thanks to sig-nificant contributions from Saint-Gob-ain (see December 2010 USGlass, page

12) and the Department of Energy. So-ladigm, too, has received financing froma variety of sources to put toward a $130million dynamic glazing manufacturingfacility in Mississippi. The company ex-pects to begin producing its insulatingglass units starting in 2012 as well. AndPleotint says it has already installedwhat it believes to be the world’s largestsingle thermochromic window, 5 feetwide by 10 feet tall. The projects usingtechnology such as this are no longerrare, as demanding energy-efficiencyrequirements drive architects to think“outside the box” with glass. Jim Wilson, chief marketing officer

for SAGE, gives credit to the codes. “Forinstance, the 2012 International EnergyConservation Code aims to increase en-ergy savings in buildings by reducingthe window-to-wall ratio to just 30 per-cent (a 25-percent reduction over theprevious level of 40 percent). It’s a codebased on a rather dated conventional

wisdom: fewer windows means betterthermal efficiency. The rapid emer-gence of new dynamic glass technolo-gies that tackle the underlying energyefficiency goals of these codes head-onis a challenge to the conventional wis-dom and offers an opportunity to posi-tion glass as a net benefit to efficiency,rather than a problem to be mitigated.”

Retrofits are expected to remainamong the stronger markets forcommercial glass companies as in-centives such as the proposed Bet-ter Buildings Initiative promote the

many benefits of improving windows and envelopes ofexisting buildings. Some manufacturers are respondingto this trend with the release of products intended to pro-vide a quick fix to outdated windows.

For example, J.E. Berkowitz and Edgetech I.G. partneredon patented technology that uses ex-isting single-pane units to create atriple-pane system without the invest-ment of a full replacement—and with-out the disruption to occupants of afull tear-out.

According to Ed Berkowitz, chair-man of J.E. Berkowitz, “RENOVATE isapproximately 50-percent less expen-sive than a complete tear-out of win-dow systems and is more thermallyefficient.”

Serious Materials in March com-mercialized the retrofit system it usedon the Empire State Building, callingit iWindow. The retrofit glass systemis installed on the inside of the exist-
