Board Moves Forward with IG Certification; Discussing CMA Product
Certification Program in Closed Meeting
A number of issues are being taken under consideration by the National
Fenestration Rating Council's (NFRC) board of directors, which met
yesterday morning to conclude the group's summer meeting in Chicago.
Some items were approved, while others will be reviewed further
in a closed meeting.
One item that will move forward is the Certification Policy Committee's
IG certification program. Roland Temple with AZS Consulting brought
the revised proposal, which calls for an implementation date of
July 2010, to the board where it was approved. This change will
make IG certification mandatory in order for any window to be NFRC-certified.
However, sine NFRC parameters only address energy performance,
some members pointed out that IG certification shouldn't necessarily
be required for units that are not specifically energy efficient,
such as those that are clear glass, air-filled.
John Lewis, technical director with the American Architectural
Manufacturers Association, asked the board to note his statement
that it "reconsider inclusion of factors that have no bearing
on the energy performance of a window."

Component Modeling Approach (CMA), several items were also brought
forward by the Technical Committee, which is chaired by Jeff Baker
of WESTLab. The board approved CMA Frame Grouping Rules and CMA
Spacer Grouping Rules language for NFRC 100. The board also agreed
to provide guidance and "binding direction" regarding
CMA Frame Values language for NFRC 100 and NFRC 200, and whether
the document should include generic values.
The Ratings Committee, chaired by Steve Strawn of Jeld-Wen, requested
the board's approval of the CMA label certification as approved
by the labeling subcommittee. Garrett Stone of Brickfield, Burchette,
Ritts & Stone P.C. spoke out against the motion, saying there
was no rush to approve the label being that the rest of the document
is not complete.
"The new label certificate contains a page of non-certified
values. Do we want [this] to have a page of non-certified values,"
asked Stone. Stone moved and the board carried, to table the decision
until the next board meeting.
"It's the board's responsibility to verify we're doing the
we need time to think about the true impact of
" said board member Mike Thoman of Architectural
Testing Inc. "We're not stalling the process; we're just evaluating
our responsibility as directors."
Wednesday afternoon's hotly debated issue of reference documents
mentioned in the CMA Product Certification Program was brought forward
to the board for guidance. Joe Hayden with Pella Corp. and NFRC
chair, said the issue would be discussed off line.
The NFRC will hold its next meeting November 3-6 in Jacksonville,
