Latest Articles in Codes & Standards

  • The Department of Energy is scheduled to release new, more stringent criteria for windows, doors and skylights that carry the Energy Star label this month. As we went to press, DOE was talking about three sets of new requirements, and while I don’t know what the numbers are, I can ask, “Are you ready?” And I’d like to focus that question on the longer term. The first set... more »
  • We have often spoken of the “101” series of international window and door performance standards. The current version of this is AAMA/WDMA/CSA 101/I.S. 2/A440-08, which allows window and door products of different framing materials and operator types to be objectively and fairly assessed for structural performance in response to wind loading, air leakage and water penetration... more »
  • The first priority in the wake of the devastating 2004 and 2005 hurricane seasons along the U.S. Gulf and Atlantic Coasts has been to upgrade construction requirements to prevent damage from excessive winds and wind-borne debris. Stronger code requirements for impact-resistant windows have since been adopted in many jurisdictions, ranging from those that reference current International Code... more »
  • If you have an ache in your belly, who do you go see—a family practitioner, a general practitioner or perhaps someone who specializes in gastroenterology or internal medicine. Medicine today has become so specialized that it is often difficult to know just who to call for help. And it is not uncommon for the recommendations of one specialist to conflict with the recommendations of another... more »
  • Mulled windows are the darling of designers—“the introduction of light and the feeling of space”—you know what I mean. A proliferation of mulls done poorly, however, can represent an “Achilles’ heel” that can cause an otherwise vigorous company to falter. We have struggled with mulls through joinery and sealant concerns, education in the trades regarding... more »

    Demand for higher levels of energy efficiency will continue to push the envelope
    Consideration of daylighting is gaining momentum within energy codes. That was the theme of a column written by Julie Ruth in the March issue of Window & Door, and it is true. This article is designed to serve as a counterpoint, however, to her assertion that “according to the two predominant codes for energy efficient construction currently used in the United States, the ideal energy-... more »
  • Adding laminated glass can significantly enhance a window’s acoustic performance
    For anyone exposed to the hustle and bustle of congested urban or suburban life—from traffic to construction to airport noise to all manner of human activity—the need to keep loud noises outside of one’s living or working area is understood. More window manufacturers today are recognizing this need and looking at how their products can address it. The following is a... more »
  • Publication can help residential and commercial fenestration fabricators avoid potentially costly problems
    Improper glazing is one of the leading causes of premature failure of insulating glass units. Whether it is due to prolonged water exposure, improper glazing clearances, improper use of setting blocks and spacer shims or component incompatibility, problems associated with glazing IG units into a window or door can be costly for manufacturers of all types of products. A new publication from the... more »
  • Report says no reason to penalize use of vinyl in LEED programs
    For years, elements of the environmentalist community have targeted vinyl as an inappropriate material for use in “green” projects. As a result, the U.S. Green Building Council has been under pressure to create a special credit in its LEED rating system against the use of vinyl. Keith Christman of the Vinyl Institute reports that the task group formed to look at the issue has... more »

    Fire officials and others are increasing efforts to protect homes in “WUI” boundary areas, and the industry needs to be prepared with sound recommendations for fenestration products
      If the danger posed by wildfires to populated areas wasn’t on the minds of fire protection officials before, it certainly was after the summer of 2002. This last “fire season” was one of the worst in the nation’s history, with nearly 6 million acres scorched. Some particularly large fires gained headlines: the Biscuit fire in Oregon that consumed nearly 500,000... more »
