Renovate by Berkowitz, JE Berkowitz
September 2, 2010
Renovate by Berkowitz is a commercial window retrofitting system that combines existing nonoperable single-pane units and insulating glass manufactured by JE Berkowitz, Pedricktown, N.J., to create an energy efficient triple-pane system. The single and double-paned units are joined together using a custom version of Super Spacer TriSeal from Edgetech I.G., Cambridge, Ohio. Installation takes...

Insulating glass unit analysis bolsters independent, third party certification
March 26, 2009
The results are in. A 25-year study of insulating glass units based on long-term analysis of in-the-field building performance indicates that independent, third-party certified insulating glass units tested to the most stringent level of testing perform better than IG units tested to lower levels of testing.

Daylighting with hermetically sealed computer- controlled louvers between lites
August 1, 2007
It’s the middle of June in the Phoenix suburb of Scottsdale, Ariz., and the intense desert sun spurs the mercury’s climb to the 108-degree mark and beyond. Roger Watson, vice president of sales and marketing for Saint-Gobain Glass Exprover NA, peers out one of two windows in the fluorescent-lit building he’s occupied since moving to Scottsdale three months ago....

Last November’s move by the Louisiana legislature to establish and enforce a statewide uniform building code creates new marketing opportunities for fenestration companies.The 11 parishes hit hardest by hurricanes Katrina and Rita already are required to meet the wind and flood provisions of the 2003 International Building Code and International Residential Code, and the rest of the state...

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,...

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...
