WDMA receives final approval on code amendments

The Window and Door Manufacturers Association (WDMA) was granted final approval of several amendments it proposed to the 2015 editions of the International Residential Code (IRC), International Energy Conservation Code (IECC), and International Existing Building Code (IEBC). Two of the new provisions remove costly impediments to replacing windows and allow manufacturers to use WDMA comparative analysis standards as an alternative to other structural requirements. A proposed amendment that would have required triple-pane windows in much of the country was defeated, as was one provision that would have discriminated against non-metal windows.
