Simple device helps to determine the correct side
July 1, 2006
Window installation has become more difficult because glaziers must ensure proper orientation of low-emissivity coatings.While fabricators have various means of determining low-e orientation during the manufacturing of insulating glass units, glaziers’ few conventional methods for on-site verification have proven ineffective, until the advent of portable detectors. With these devices,...

Preserving and improving older buildings offer glazing contractors great opportunity and challenge. With new construction projects, aesthetic and performance criteria can be clearly defined by owner, architect and construction team, and window systems can be engineered, fabricated and installed per the specifications. With renovation projects, the glazing contractor and window systems...

An electrician must do part of the job
October 1, 2005
Installing Thermique windows requires a trained glazier to set the insulating glass unit and route the electrical leads correctly into the window frame, and a licensed electrician to terminate the electrical wiring connections.

The play of glass in the preservation of art, history
September 1, 2005
Museums house antiques, treasures and heritage. They conserve history and tell the story of who we are. People visit museums to view exhibits, preferably well lit. Curators and visitors, however, express dramatically opposing views of what kind of light best illuminates exhibits in a museum. The trend runs toward natural light from large expanses of glass. Nearly every current museum renovation,...

A little-known measure, damage-weighted transmittance, emerges as a way to assess fading risks
September 1, 2005
In choosing the most appropriate glass for commercial and residential projects, more architects look at the issue of fading, specifically with regard to fabrics, finishes, carpeting and artwork that will occupy the interior of their finished buildings.In assessing the potential fading risks associated with the glass they specify, most architects look at a single measure on the performance data...

When antiquities, priceless collections, venerable art, fussy curators and deep pockets come into play.
September 1, 2005
Museums and art galleries present challenges to glazing designs, given the tight environmental conditions that must be met. Consideration must be given to many parameters, often conflicting, including the quality and quantity of light, ultraviolet resistance, aesthetics, thermal performance, condensation resistance, strength, security performance, safety and cost. For a best-practice curatorial...

Complex subject made easy
September 1, 2005
Would you want to consider a “climate” inside your insulating glass unit? Probably not. During manufacture, a volume of air is trapped in IG at a certain temperature and relative humidity, then exposed to the forces of nature, heat, cold and pressures. Without a desiccant to dry the air space, the trapped moisture condenses and creates “rain” inside the IG when the...

Owners of The New York Times Co., along with researchers at the Environmental Energy Technologies Division of Lawrence Berkeley National Laboratories in Berkeley, Calif., constructed a 4,500-square-foot mock-up of the paper’s new headquarters in the parking lot of its College Point, Queens, printing facility. The researchers used the model of the southwest corner of the headquarters for...
