Spring Meeting Concludes with Attachment Rating Discussions
National Fenestration Rating Council's (NFRC) spring meeting concluded
yesterday in Nashville, Tenn., with the open board meeting. For
once the Component Modeling Approach (CMA) development wasn't the
meeting's only controversial topic. In fact, no CMA action was taken
during the board meeting, as all of the ballots discussed earlier
in the week were returned to task groups for additional work. Instead,
members debated the development of a means for rating attachments
(i.e. window film, storm windows, blinds, etc.).
The discussions had begun on Wednesday during the attachments subcommittee
meeting. Dave DeBlock from ODL, chair of the dynamic attachments
for swing doors task group, has been heading efforts to develop
an attachments rating system. The system separates the way a consumer
sees the window and the attachment, and provides a lettering scale
rating (i.e., A products, B products, C products, etc.) for the
attachment only; not the performance of the entire system. Designed
as such, if a storm window, for example, was to be rated in the
same fashion as a window, the performance values would be much lower
than those of the windows alone. However, what a consumer might
not understand is that such a rating on a storm window, once installed
into the window system, will result in even greater performance
Concerns arose over one ballot negative, which said having two
separate rating systems rather than one uniform system wouldn't
fall under NFRC's standard procedures. Since the negative was found
persuasive the subcommittee will have to go back and re-create the
Concerned over the fact that the attachment rating system was developed
precisely according to NFRC procedure, DeBlock took the opportunity
to express his concerns to the board during yesterday's meeting.
"We've completed our task. We created a way to rate [attachment]
products," said DeBlock. "Using the NFRC procedure these products
could now be rated and labeled." He explained that the rating system
would allow consumers to assess what they need to do-replace their
windows or incorporate an attachment-given their own resources.
No board action was taken on the matter. As the situation stands,
the intent remains to create a uniform system for rating attachments.
Whether it's the same system NFRC follows for ranking doors and
windows or something different is yet to be determined.
The NFRC's next meeting will take place July 28-31 in Chicago.
