  • Asymmetric triple-pane construction and advanced gas filling techniques provide new alternatives to improve performance numbers
    Conventional wisdom says R-5 windows are too costly to manufacture. This assumption is largely based on experience employing older technologies for fabricating high-performing triple IG units. Several recent developments challenge the assumption that R-5 cannot be reached affordably. One is the addition of 4th surface low-E glass coatings in dual lite units. Another is the introduction of... more »
  • We knew the day was coming—the Environmental Protection Agency recently released its draft proposal for the future of the Energy Star program for windows, doors and skylights last week. With a plan that calls for changes to take effect in January 2014, the draft includes U-factor requirements that may  lessen the need for manufacturers to pursue triple-glazed products to carry the... more »
  • "We think the future is dynamic windows," said Marc LaFrance, the Department of Energy's technology development manager with oversight over the agency's windows and building envelope programs speaking at a recent Windows Technology Roadmapping Workshop. Dynamic glazing was also high on the agenda at the Window & Door Manufacturers Association Technical Conference, which... more »

  • Biggest challenge for most manufacturers likely to be new U-factor requirements
    The fenestration industry is facing significant changes that will likely increase thermal performance standards by 30 percent to 40 percent within the next few years. Higher performance levels are demanded by the International Energy Conservation Code and the ICC 700 National Green Building Standard, and soon the Energy Star Windows, Doors & Skylight program. The Environmental Protection... more »
