Summer Meeting Starts in Minneapolis
The National Fenestration Rating Council's (NFRC) summer meeting
began yesterday morning at the Crowne Plaza Northstar Hotel in Minneapolis.
The meeting opened with discussions held by the tubular daylighting
devices task group, PCP task group, optics implementation task group,
NFRC 101 and 103 standards revision task group and the fenestration
glossary and terminology task group.
The revision task group addressed negative ballots to continue moving
the standards forward.
William duPont of Synergy Consulting had recommended to not approve
the Procedure for Determining Thermo-Physical Properties of Materials,
NFRC 101, unless the group looked into using additional standards,
such as ASTM F 433, to help with testing.
"One of the things I was trying to do was add things to make
this more versatile," said duPont.
After discussion, his comment was withdrawn with a recommendation
for the task group to look into further testing.
With regard to NFRC 103, Verification Program for Thermo-physical
Property Data, the group discussed the cost of the challenge procedure
to the council and reasons for having a peer review of all labs
and manufacturers, as NFRC-accredited labs are not peer reviewed
Following these sessions, the membership filled the Great Lakes
Ballroom to sit in on the component modeling approach road mapping
task group (non-residential), a ratings subcommittee, chaired by
Mahabir Bhandari of Carli Inc. Reports were offered by the three
non-residential working group/task groups, and presentations were
made on desiccant materials and spacer grouping. The group also
discussed new business; among other topics, the members discussed
the procedure for certifying custom walls and the possibility of
simplifying the testing and simulating procedure to keep from putting
custom wall manufacturers at a disadvantage.
Following the membership luncheon and opening session, at which
executive director Jim Benney stressed the council's continuing
goal of simplification, the technical interpretation policy committee,
accreditation policy committee and certification policy committee
offered reports on their activities since the council's last meeting.
Next, the labeling forum opened a discussion of the types of NFRC
labeling-temporary labels, permanent labels and label certificates-and
the information required on each type of label.
Today's meetings will offer reports from the research and technology
The meeting continues through Thursday, July 27.
