Air Leakage Document to Reference AAMA 101; CMA Subcommittees to
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.
