  • Focus group session makes clear that energy performance far outweighs other priorities, but other green considerations can't be ignored
    Most architects involved in the green building movement think windows, doors and skylights are “green.” That view was expressed at a recent focus group sponsored by Window & Door and Velux-America, although it was also evident that definitions and priorities are not yet firmly established when it comes to choosing green products. Organized by Market Resource Associates,... more »
  • Companies say hurdles remain, but new prototypes are on the way
    Vacuum glazing as a concept is nothing new. Glass researchers have been investigating the idea for years. Nippon Sheet Glass of Japan started offering a vacuum glazing product in the 1990s. Most window and door manufacturers, however, don't see the available technologies to be commercially viable yet. Now, at least two companies say the long-discussed concept could... more »
  • Although it's counterintuitive to think about global warming when a hard winter besieges the upper Midwest, we in the fenestration industry ignore the implications of global warming at our peril–at least in the sense that doing so will likely hamstring our businesses. The human role in global warming is heavily debated, but the political role is hardly questionable. As a result, regulations... more »
  • Window and door companies have been living in “energy efficiency land” for decades. I type “energy efficient” so many times in a month I might as well set a quick key function on my keyboard. Energy efficiency to us is like texting to teenagers—it’s in our blood, it’s what we do, it’s how we communicate with our BFFs. Well, snap, snap, people—... more »
  • Few people in the window and door industry are sorry to say goodbye to 2008. We reported more than enough stories this year on plant closings, lay-offs, restructurings, and even complete shutdowns of companies. I just wish I could say I was starting the new year brimming with optimism. Current forecasts for the economy in general, and the new construction and home improvement markets, don’t... more »

    Boston—While other trade shows may be struggling, the Greenbuild International Conference & Expo held here last week was bursting at the seams. With over 25,000 attendees crowding the aisles of the Boston Convention and Exhibition Center, the show, organized by the U.S. Green Building Council, provided evidence that demand for green is “real,” as one window manufacturer... more »
  • Right now, there’s much talk about the need to bail out U.S. automakers. Those in favor say actions are necessary to save the economy from falling into depression and put the U.S. in a leadership role in next generation energy efficient cars. A stimulus program for replacement windows and doors... ...is needed and the industry should lobby for it. ...might be... more »

    Getting ready for new NFRC and Energy Star mandates set to go into effect by 2010 is critical
    For certification, IG must pass accelerated weathering tests, which simulate weather cycling from -20 degrees F to 140 degrees F with high humidity and ultraviolet radiation exposure over a 63-day period. Based on the recommendation of the Insulating Glass Industry Durability Advisory Group, the U.S. Department of Energy plans to require insulating glass certification as a prerequisite... more »
  • This is a sidebar to the article A Manufacturer's Guide to IG Certification. What is ASTM E 2190? ASTM E 2190 was approved in 2002 as part of a continuing effort to harmonize North American standards for IG testing and performance. E 2190 is a standard specification for IG unit performance and evaluation designed to be equal to or improved over its predecessors ASTM E 774 (U.S.) and CGSB 12.8 (... more »
