Window Replacement Proposals Approved During Code HearingsMay 4th, 2012 by DWM Magazine
The International Code Council (ICC) reviewed two proposed changes to the International Building Code (IBC) yesterday, and two of these deal with window replacements and were approved as submitted. One related to window opening control devices, while the other had to do with the size of the window opening.
The first, G 225-12, proposed that in all windows in group R-2 or R-3 buildings containing dwelling units, window opening control devices (WOCD) complying with ASTM F2090 shall be installed where an existing window is replaced, according to section 3048.1. Julie Ruth, representing the American Architectural Manufacturers Association and Jeff Inks, vice president of codes and regulatory affairs for the Window and Door Manufacturers Association (WDMA), both spoke in support of the proposal, which ultimately passed 10 to 1.
Ruth said the proposal would apply to existing openings and that AAMA has been hearing from its members on this issue.
“We think this proposal achieves the objectives of the code when windows are replaced,” said Inks.
Inks also submitted G227-12 regarding replacement window openings. According to the proposal, which relates to section 3408.1 of the code, where windows are required to provide emergency escape and rescue openings in group R-2 and R-3 occupancies, replacement windows shall be exempt from the requirements of Sections 1029.2, 1029.3 and 1029.5 provided the replacement window is the manufacturer’s largest standard size window that will fit within the existing frame or existing rough opening.
The intent of the proposal is to ensure the IBC does not discourage or prevent improvements in fire safety in older residential occupancies by requiring replacement windows meet all of the provisions of Section 1029 when doing so could require increasing the size of the rough opening or altering the interior wall.
“We proposed this because we are getting calls at the local level as to how egress windows apply to this section of the code,” said Inks. “In many cases this is not an issue but we are proposing language clarifying the intent …The intent is to avoid a situation where a window replacement is avoided because a jurisdiction says a window opening must be bigger.”
The proposal passed as submitted 7-4.
The code hearings are taking place this week in Dallas.
