  • 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 »

    Niche products are gaining mainstream appeal
    We don’t have to get up off the couch to change channels anymore, very few of us actually slide a key in the lock to open a car door and maps rest neatly in the glove box thanks to the GPS on the dash. This push-of-a-button mentality is making its way into window and door hardware, too, as suppliers introduce high-tech products aimed to make life simpler. These products aren’t just... 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 »

    Manufacturers find success in strict, custom niche
    There’s a spectrum of what constitutes a “historic” window. Depending on guidelines outlined by historical trusts and preservation societies and decision makers involved with the project, historic renovation solutions can range from refinishing and reglazing the original sash and frames to recreating a specific look with a brand new window made to incorporate historic features.... 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 »
  • Recent survey finds high awareness level and eagerness to adopt technology
    The architectural community is increasingly committed to the sustainable design goals of lower energy consumption and greater levels of building occupants’ well-being and productivity. With the emergence of the green building movement, the window, door and glass industries can expect to see increased demands for higher performing products, including, notably, smart glass. The U.S. Green... more »
  • The green building movement is offering us a real opportunity
    When it comes to business today...consumers today...selling today...everything is coming down to a single color: Green. Building greener homes is catching on at a spectacular pace. Homeowners are looking for more and more ways to make their surroundings and living space environmentally friendly by choosing green products. This green movement is the result of a combination of factors: global... 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 »
