  • As some of you are probably aware, the International Code Council final action hearings on its Group A+ (non-energy) related proposals took place in May 2010 in Dallas.  What you may not have been aware of is that the final action on some of these proposals had already been determined well before the Dallas hearings began. Although the result was not finalized until the vote was taken on... more »
  • In a recent article in Window & Door Magazine, Lawrence Industries alleged concern about levels of lead in zinc die castings—a material commonly used in the manufacture of window hardware. Included in this claim was the possibility of potentially unsafe concentrations of lead at surface levels of these products. In order to clear up any misconceptions that may have stemmed from these... more »
  • More competitive pricing and focus on ROI also enables more buyers to justify purchase of pultruded products
    Fiberglass framing materials are enjoying more significant market recognition as of late. Although it is not a new technology, the heightened global emphasis on green building and sustainable building practices is highlighting the properties of fiberglass and increasing demand for such products. The strength of fiberglass enable windows and doors to be produced with narrow framing.... more »
  • I am one of those people who tend to not do well when I have a lot of things coming at me at the same time. I am not good at juggling–whether it be trying to keep balls in the air or making sure I don’t miss something when I have multiple business or personal responsibilities. This is why I tend to focus my attention primarily on what the International Code Council is doing. From time... more »
  • This week's WDweekly suggests our industry is getting more colorful. One of our news items this week focuses on Soft-Lite, which has been promoting color options on its vinyl windows and doors for some time, but also seems to be part of a growing trend. Over the past year or so, a growing number of manufacturers have added new color and finish options or capabilities. Much of the activity is in... more »
  • It appears that the other shoe in the Energy Star program for windows, doors and skylights as adopted in April 2009 is poised to drop. On the heels of the March 31, 2010 implementation deadline for transitioning to the newly upgraded requirements, the “Phase Two” tightening of criteria–originally slated for 2012 or 2013–is now folded into a more comprehensive and... more »
  • Last week, I asked about the impact of the DOE's R-5 window program.  One possible effect the program could have–which no one mentioned specifically, but which I have wondered about since DOE first announced it–was a possible shift away from the industry's usual use of U-factors to R-values.  U-factors, as long as NFRC has been around, has been the standard way to rate the... more »
  • Last year, the Department of Energy announced the launch of the R-5 windows and low-E storm windows volume purchase program, designed to find buyers for highly insulated windows and match them with manufacturers that would offer such products at an affordable price. Checking the DOE Web site this week to see if they had announced which companies had been accepted for the program, I learned they... more »
  • Another new code? Yes, now in development at the International Code Council is the International Green Construction Code or IgCC, as it has been dubbed. If you thought the ICC already published a code for green construction, that was actually not a code, but a standard.  ICC jointly published the National Green Building Standard with the National Association of Home Builders in 2008. That... more »
  • New codes expected to spur more development and options
    Over the past several decades, safety advocates, building code officials and the window and door industry have looked for ways to prevent children falling through windows. In recent years, those efforts led to the concept of the window opening control device or WOCD, a new type of hardware that many window and door manufacturers are now studying and some have even integrated into... more »
