USGNN Original StoryNFRC Air Leakage Document to Reference AAMA 101; CMA Subcommittees to Meet Today

Several technical committee subcommittees met yesterday afternoon as part of the National Fenestration Rating Council's (NFRC) Summer Meeting taking place in Chicago. Several ballot issues were handled that will now move forward to committee level.

During the air leakage subcommittee meeting, chaired by Mike Thoman from Architectural Testing Inc., members discussed an action item from the springboard meeting in Nashville (CLICK HERE for that story). Since determining air leakage performance is already covered by other industry programs, the subcommittee has been discussing whether NFRC 400-2004 should be removed from the 2009 documents. The group decided NFRC 400 should remain in the 2009 documents, but would heavily reference the American Architectural Manufacturers Association (AAMA) 101 document in the technical specification.

During the U-factor subcommittee meting, the language being developed for the NFRC 100 section for rating dynamic attachments for swinging doors was again debated, much as it was before during the spring meeting in Nashville (see related article link above). One ballot negative disapproved, saying the rating should be for a general class of products and not a specific single-class product. The motion to find the negative persuasive, however, failed, and the ballot will now return to task group for further review.

In addition, Component Modeling Approach (CMA) subcommittees will also meet later today. Stay tuned to USGNN.com™ for more news from the NFRC's Summer Meeting.
