Product> Exterior Glass: Eight options with special functions built in

The role of glass continues to expand in architecture as new performance properties and aesthetic qualities come to market in a steady flow. From photovoltaic glazing to printing technologies that address the issue of avian impacts, the material has become an active, dynamic force in buildings. SunGuard SNX 51/23 Guardian For commercial use, this high-performance, low-E glass has a VLT above 50 percent and a solar heat gain coefficient below .25. Solarban z75 PPG Featuring a neutral, cool-gray tint, this low-emissivity glass offers an intelligent combination of visible light transmittance, solar control, and light control. View Dynamic Glass View As the sun intensifies, a nanotech interlayer regulates an electric current that shifts ions in the glass, automatically darkening them. Offered in panels up to 5 feet by 10 feet. Ornilux Mikado Arnold Glas  This bird-protection glass features a patterned UV coating that is visible to birds, but virtually transparent to the human eye. i-Glass Oldcastle BuildingEnvelope  This screenless technology can print multiple colors and complex designs on exterior and interior glass. LightZone SageGlass  Variable tint zones within a single pane of electrochromic glass allows great flexibility for managing solar heat gain and glare. CLASS Sapphire Saint Gobain In sheets up to 9 inches by 26 inches and 12 inches by 24 inches, this transparent ballistic-resistant material achieves a 40 percent lighter and 40 percent thinner system than a glass-only design. DigitalDistinctions Etch Ink Viracon This ink simulates the look of acid-etched or colored-etched glass without high-pressure sand blasting or dangerous acids.

Green Monsters

Isn't it annoying when you're trying to do your part to go green and then things catch on fire? In what some are calling a case of "green on green crime," a low-e glass window has been accused of melting the side-view mirror of a nearby Toyota Prius in Southern California. The Prius owner noticed a concentrated beam of sunlight reflecting off her neighbor's windows, which had been treated with a highly reflective energy efficient coating, after being told by her Toyota dealership that nothing was wrong with her car. It wouldn’t be the first time good windows turned bad: Las Vegas' Vdara hotel made headlines when its "death ray" reflected super-hot beams of light onto its pool deck, allegedly burning some sunbathers. Following reports of melted vinyl siding, pool covers, and car parts across the country, the National Association of Home Builders has launched a study about the amount of concentrated sunlight reflected from energy efficient windows.

Could Low-E Windows Melt Your Neighbors?

Every rose has its thorn, including those supposed holy grails of sustainable products. CFLs contain mercury. Biofuel competes with farmers for topsoil. Now high performance windows, particularly those of the double-pane, Low-E variety, have become the bane of suburbia, as they can apparently melt your neighbors home—or at least their vinyl siding. That was the news from a surprising report on Boston's Channel 5 news, sent to us by Infared New England, who tests for these sorts of things. It turns out that under the right circumstances, the windows work as magnifiers, focusing light on nearby buildings like a rascally child picking off ants. At least two area women have suffered the consequences, and there are plenty of similar videos on YouTube. So let this be a warning to you about the risks of vinyl siding next time you consider using it on a project. (Okay, let's be honest, if you're reading this, god forbid such a thought ever crossed your mind. Still, it's pretty crazy, the unintended consequences of this business of ours. Eh, Frank?)
